TSLint: Invalid config file.

[PaulSinnema]

Webessentials nightly build 2.3.5 gives me 'TSLint: Invalid config file.' on rebuild all in VS2013.

Hello @PaulSinnema.

Have you made changes to tslint.json?

If so can you show paste the file here.

If not; you are using the default one, which comes with Web Essentials -- please delete it from %userprofile% directory (this means you might be using the old one). Web Essentials will auto restore the default one from its settings store.

Removed the tslint.json from the %userprofile% directory. Problem remains.

How config files are located by linters: (in this case config file is tslint.json and input file is filename.ts)

• It looks in the current directory of the input file.
  • If found, this config takes the precedence and is used by the linter. If not found, it keeps searching.
• Then parent directory of the above directory.
• Continues till it reaches the root of the current drive.
• Then it looks into the HOME directory (aka %userprofile%).

(those are the standard steps taken by node-based linters, at this point if the config file isn't found anywhere, the linter will throw error: config-not-found)

• As a fallback, Web Essentials preemptively detects the problem and restore a config file in the user-home, if none of the above is found.

Questions:

• When you deleted your tslint.json, WE must have restored one in HOME dir from settings store. Was this the case?
• If no, then it means you have another tslint.config, somewhere in the directory structure of your .ts file till the drives root.
• If yes, then its a weird problem. I just tried with and it showed me tslint errors in Error List.

I encountered the same issue: The warning TSLint: Invalid config file was constantly there.

Removed tslint.json from my user directory. No change

Checked with procmon.exe which tslint.json is accessed. It was the one in the directory set by the %HOME% env variable. There was no tslint.json file. I created one with content "{}", so empty json object.

Restarted VS and warning is away. (Reloading solution was not enough, the error provider of vs often hangs a bit)

I had the same issue with VS2013 Update 3 saying "*.ts compilation failed: TSLint: Invalid config file." for each .ts files in solution. I downloaded the default config file and copied to %userprofile% and it worked.
