Parsing Error: Cannot read file ‘tsconfig.json’ #

To solve the error «Parsing Error: Cannot read file ‘tsconfig.json'», update your .eslintrc.js file to set the tsconfigRootDir option to __dirname to force eslint to resolve your project configuration relative to the folder where .eslintrc.js is located.

Open your .eslintrc.js file and add or update your parserOptions object to look like:

By setting the parserOptions object we tell ESLint which JavaScript language options we want to support.

The sourceType option is set to module to indicate that we want to support ES6 Modules.

Once you’ve updated your parserOptions object, you might get an error:

If you got the «parserOptions.project» has been set for @typescript-eslint/parser error, create a tsconfig.eslint.json file in your root directory, right next to your tsconfig.json file.

Make sure to add all of the directories you want to lint in the include array.

Now open your .eslintrc.js file and update the project property to point to the eslint-specific tsconfig file.

Your error should be resolved, if it isn’t try restarting your IDE.

This is needed because adding the parserOptions.project option to a TypeScript project causes ESLint to throw an error if we try to lint files that aren’t included in our TypeScript project.

In short, add all the files that you want to lint, but are not included in your tsconfig.json file to the include array in your tsconfig.eslint.json file. These will most likely be config files that are located in your root directory.

Alternatively, you can add any of the files in which you see the error to your .eslintignore file if you don’t want to lint them.

If the error «Parsing Error: Cannot read file ‘tsconfig.json'» is still not resolved and you use the VSCode IDE, create a .vscode folder in the root directory of your project.

Add a settings.json file in the .vscode directory and paste the following contents.

This file assumes that you want to lint an src directory.

If your project has 2 directories that you want to lint, e.g. frontend and backend , update the workingDirectories array to look like this:

The setting instructs ESLint how to resolve config files ( .eslintrc.js and .eslintignore ) relative to our working directory.

For example, if your project is in a user/typescript/ directory and you open your code editor in the user/ directory, you might get the error.

Instead, try to navigate to the user/typescript/ directory first and then open your code editor.

«Cannot read file» with lowercase name in mac #2213

Comments

I’m using eslint on mac. I have a large React project in js, and I’m trying to start using ts. I’ve changed only one file to ts (in my shared/utils/ folder) and tested eslint.

Expected to pass, but got this error:

What’s weird is that /Users/* folder became /users/* folder — so I assume this is what caused the file to be not found.

This is what running with —debug showed me:

Most of the eslint config ( .eslintrc.js ) is this:

Versions

package version
@typescript-eslint/parser 3.2.0
TypeScript 3.9.5
ESLint 7.2.0
node 12.6.2
npm 6.14.4

The text was updated successfully, but these errors were encountered:

macos is case INsensitive for filenames, which is why typescritpt lowercases the paths.

I’m not able to repro this — could you please provide a repro repo to help investigate?

Solved it thanks to the idea to create repro repo. When I succeeded recreating it I discovered the problem.
It was in the eslintrc portion that I omitted because it was related to internal code.
I had this code, using an object called appsMapping that has the names of all apps in our repo:

What I haven’t noticed is that we did there join to a string, and then spread operator on the string. The path was invalid.

Bug Report

I installed nest and start new project. and there is a problem with eslint: in .eslint.js I got error

eslint in code also not working, and command npm run lint doesn’t find any problems.

Current behavior

Input Code

I didn’t change anything actually.

Environment

is it reproduced or is it just me?

ok, but what should I looking for? looks like I don’t get relevant result when I google Parsing error: «parserOptions.project» has been set for @typescript-eslint/parser.

edit: well, I did some researches. first, eslint is working. I can’t understand where is the bug. web storm says that:

but

but if I do something like that: project: ‘../tsconfig.json’, , then

so, eslint really trying to find the tsconfig file, and he can found it, but ide is showing error. how to fix that? or it doesn’t matter? lint works anyway.

@OlegBrony, looks like this happened because webstorm automatically tries to apply eslint to .eslintrc.js file and parse it with typescript config (which is not working with js files). You can safely ignore it.

I believe this issue should be a bug.. I am having the same error. The script lint runs but doesn’t fix or complain about any of the many linting errors I left in the code.

@BrenoGO can you provide a minimum reproduction?

Just run «nest new my-project» («@nestjs/cli»: «^7.0.0»,). The .eslintrc will show the error of this issue’s title.
I ran the eslint —init, now I will configure it. I thought it would start already configured.

I am using the nest 7.4.1.
Using the git clone https://github.com/nestjs/typescript-starter.git, it’s the same..
Does anyone does these procedures and the eslint works fine?! Could be something with my VSCode?
In other projects I always use it configuring from beginning with eslint —init and is working fine..

@BrenoGO using the latest version of the Nest CLI I created a new project

Once the installation finished I moved into the new project’s directory

And then I ran the linter

Just to be sure, I then ran eslint directly

Not sure what you’re facing, but the configuration setup is fine in terms of running the lint command. It sounds like the problem is with the IDE, as in eslint trying to lint the .eslintrc.js file. As that doesn’t really happen from the lint commands, I don’t really see it being an issue. If you want to fix it though, you can create an .eslintignore file and add all .js files or specific ones, just like you would for a .gitignore

The problem is when we go to a file and leave some code out of pattern, the eslint does not report any errors..

I thought this should be not happening as expected because of the error in the .eslintrc below:

Solved by replacing filename from .eslintrc.js to .eslintrc and removing module.exports etc.

Doing that the error in .eslintrc will be gone. But still some basic rules like «semi», «comma-dangle» and «quotes» are not being reported by the eslint. It seems like we have to configure it all by ourselves..

You should install this dependencies
yarn add eslint-config-prettier eslint-plugin-prettier —dev or npm install eslint-config-prettier eslint-plugin-prettier —save-dev
And replace extends object in .eslintrc by this

«extends»: [
«plugin:@typescript-eslint/eslint-recommended»,
«plugin:@typescript-eslint/recommended»,
«prettier/@typescript-eslint»,
«plugin:prettier/recommended»
]

After VsCode reload should work

Does not worked for me

@lucasluca , did you also did that?

Solved by replacing filename from .eslintrc.js to .eslintrc and removing module.exports etc.

what did not work for you?

I did exactly the same thing. Added the packages and extended what was recommended. I still have the same issue.

I had to change the extension of the .eslintrc.js to ts . Then it was resolved.

SO. all the fix was about

  1. changing name from ‘.eslintrc.js’ to ‘.eslintrc’.
  2. making json from object (and fix all json syntax errors).

Adding «createDefaultProgram»: true to the tsconfig, after doing #4900 (comment) fixed it for me.

In my opinion, NestJS creates an erroneous configuration.

The file .eslintrc.js shoud look like this:

By adding ignorePatterns: [‘.eslintrc.js’] eslint is told to ignore the .eslintrc.js file itself.

Otherwise it results in an error, because eslint tries to lint the .eslintrc.js file, even though it is not included in the tsconfig.json configuration.

The lint command that Nest provides in the package.json works fine, and I can’t reproduce this on VSCode unless I open up the .eslintrc.js file. However, I do see where this is coming from, so if you’d like to create a PR to the typescript-starter to add that line in, please feel free to do so. I’ll double check if any other locations would need it as well.

Ошибка анализа: не удается прочитать файл ‘… / tsconfig.json’.eslint

Ошибка Parsing error: Cannot read file ‘. /tsconfig.json’.eslint отображается во всех .ts файлах в src папке, включая index.ts .

Понятия не имею, как настраивать конфиги. Проблема просто показывает красную линию и делает файл красным. Однако все компилируется и работает нормально. Весь проект Node был создан с использованием интерфейса командной строки firebase.

Я попытался перезапустить VScode, очистить кеш, и все безрезультатно. Я предполагаю, что мне нужно изменить некоторые пути, но я не очень хорошо умею изменять файлы конфигурации, поэтому я не хочу случайно сломать весь проект.

По умолчанию project s (in parserOptions ) разрешаются относительно текущего рабочего каталога. Если вы запустите eslint в другом рабочем каталоге, чем содержащая его папка tsconfig.json , @ typescript-eslint / parser не сможет найти файл.

Чтобы исправить это, вы можете установить tsconfigRootDir значение __dirname , которое заставит парсер разрешить конфигурацию проекта относительно .eslintrc.js :

Подход, специфичный для VSCode, который сработал для меня, заключался в создании .vscode папки в корневом каталоге проекта и добавлении следующего свойства в settings.json файл внутри нее:

Это «src» может быть любой каталог, который должен находиться в области видимости eslint.

обновите файл eslintrc.json следующей строкой:

Ошибка анализа: не удается прочитать файл ‘d: \ test \ testproject \ tsconfig.app.eslint.json’.eslint Одна из основных проблем, с которыми я столкнулся здесь, из-за способа открытия папки проекта в коде vs.

Предположим, что структура папок — d: \ test \ testproject, где testproject — это проект angular, который вы используете.

если вы открываете тестовую папку в vs code, переходите к testproject, как показано ниже
