[英]Typescript / Eslint throws "Cannot read file tsconfig.json" in every project I start
In other threads I read that the issue might come when eslint and tsconfig.json are not in the same working folder, but I have all the files in the project's root folder.在其他线程中,我读到当 eslint 和 tsconfig.json 不在同一个工作文件夹中时可能会出现问题,但我在项目的根文件夹中拥有所有文件。 Somehow, after initializing the project, the thrown error seems to try to find tsconfig.json in the parent folder of the project (so, outside the project):
不知何故,在初始化项目后,抛出的错误似乎试图在项目的父文件夹中找到 tsconfig.json(所以,在项目之外):
Let's say the project is in: '\parentFolder\ProjectRoot' tsconfig is in the route: '\parentFolder\ProjectRoot\tsconfig.json假设项目位于:'\parentFolder\ProjectRoot' tsconfig 在路径中:'\parentFolder\ProjectRoot\tsconfig.json
The eslint error I get (at the top of index.ts) is the following:我得到的 eslint 错误(在 index.ts 的顶部)如下:
Parsing error: Cannot read file ' parentFolder \tsconfig.json'解析错误:无法读取文件“ parentFolder \tsconfig.json”
The contents of \parentFolder\ProjectRoot are: \parentFolder\ProjectRoot 的内容是:
The steps to get to this point have been:达到这一点的步骤是:

index.ts (I get implicity errors here in req and res, I imagine caused by the fact that tsconfig can't be found). index.ts (我在 req 和 res 中得到隐含错误,我想是由于找不到 tsconfig 的事实造成的)。
const express = require('express');
const app = express();app.use(express.json());
const PORT = 3000;
app.get('/ping', (_req, res) => {
res.send('pong');
});
app.listen(PORT, () => {
console.log(`Server running on port ${PORT}`);
});
edit:编辑:
I had typescript installed globally (and also as a dev dependency in these projects).我在全球范围内安装了 typescript(也作为这些项目中的开发依赖项)。 Thinking this might be the issue, I uninstalled the global version of typescript.
考虑到这可能是问题所在,我卸载了 typescript 的全球版本。
When checking all global packages with npm list -g --depth 0, I get the following:使用 npm list -g --depth 0 检查所有全局包时,我得到以下信息:
I don't know if that would be related to the issue.我不知道这是否与这个问题有关。
What worked for me was on the.eslintrc of the folder you are on to add:对我有用的是您要添加的文件夹的.eslintrc:
parserOptions: {
project: 'tsconfig.json',
tsconfigRootDir: __dirname // <-- this did the trick for me
}
I'm putting this answer here as an idiot-proofing measure.我把这个答案放在这里是为了防止白痴。 This can also happen if you open the project in the wrong folder.
如果您在错误的文件夹中打开项目,也会发生这种情况。 I got this error when I opened the parent directory of the project instead of the project directory itself.
当我打开项目的父目录而不是项目目录本身时出现此错误。 I had a project in
GitLab -> projectFolder
and opened GitLab.我在
GitLab -> projectFolder
中有一个项目并打开了 GitLab。 I got the error saying tsconfig.json
could not be read.我收到错误消息说
tsconfig.json
无法读取。
