"Parsing error: File 'tsconfig.json' not found" when path has any caps and is on non-system drive (C:).

[matracey]

What code were you trying to parse?

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "module": "esnext",
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es2015",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2018",
      "dom"
    ]
  },
  "angularCompilerOptions": {
    "fullTemplateTypeCheck": true,
    "strictInjectionParameters": true
  }
}

What did you expect to happen?
I expected the tslint.json file to be parsed and for the eslint results to be returned.

What actually happened?
I received an Parsing error: File 'tsconfig.json' not found.

I have created a repository where the issue can be easily reproduced by cloning on Windows to a drive that isn't your system drive (C: in most cases).

Versions

package	version
@typescript-eslint/parser	^2.19.0

i'v tried to reproduce this issue with repo that you provided and i don't see any issues when executing eslint in D:\Projects\typescript-eslint-caps-path-issue-repro\ANGULAR\

$ eslint . --ext .ts,.js
Tried to lint D:\Projects\typescript-eslint-caps-path-issue-repro\ANGULAR\e2e\protractor.conf.js but found no valid, enabled rules for this file type and file path in the resolved configuration.

there can be one issue, that your path is to long, (windows by default support only 260 chars in full path), you can change this easily in group policy if you are pro/enterprise user or in registry if you have home version

I don't think it's a MAX_PATH issue - my path to the tsconfig.json file is only 74 characters long. TSLint works just fine in the same folder also. As a side note, I'm running eslint using node_modules\.bin\eslint - I don't have it installed globally, but installing globally still sees the same issue.

Strangely enough, adding the --ext .ts,.js switch doesn't work for me either - I'm not matching any files.

Oops! Something went wrong! :(

ESLint: 6.8.0.

No files matching the pattern "." were found.
Please check for typing mistakes in the pattern.

I'm thinking I can try to debug the part of typescript-eslint/parser that loads the tsconfig.json file to see if I can see any reason why it isn't working. Not sure where that is right now, but I'll look through the source for it and try to debug.
