'Error starting TypeScript language service in WebStorm 2018

I'm new to using WebStorm (v2018.2 on Windows 7) and trying to work with TypeScript. And I am getting following error, despite trying many combinations of the TypeScript configuration settings in WebStorm.

Error:Timeout on starting language service process

As a result, I'm unable to compile my .ts files within the IDE.

TypeScript is working fine from command line (i.e. successfully able to run tsc to compile .ts files).

I have thoroughly reviewed the WebStorm help documentation and other tutorials, but nowhere have I seen this error mentioned or how to resolve it.

I've encountered this error a few times myself, and in my case it seems to be a problem with the node interpreter WebStorm is trying to use.

Earlier this week something I had installed via mac's homebrew package manager added a new/broken build of node to my system as a dependency. When I started having issues with webstorm, I opened preferences > Languages & Frameworks > TypeScript and saw that the Node interpreter was set to /usr/local/bin/node instead of my usual nvm path. I opened a terminal and tried running the node executable it was pointed to, and found that it was throwing an error.

A lot of the specifics aren't really comparable to your situation since you're on Windows, but I think it's probably a similar root cause, a bad node executable is the only thing I've ever seen cause this error message.

Just go to Typescript in settings sidebar, and you reference the correct path of node interpreter in node interpreter input that you see there

I had same issue. Problem was setting current node interpreter version in intellij (Settings->Languages&Frameworks->NodeJS and NPM)

I got this error in an Angular TypeScript project. ESLint was linting .ts files obviously. However, I also had some HLS video chunks in my project which also use a .ts extension. When I deleted the HLS chunks, the problem disappeared. I tried adding the folder containing the HLS chunks to .eslintignore but no joy. I'm still refining how to deal with the issue without deleting the HLS chunks. I may be forced to change the extension of the chunk files but hoping I can find a better solution.

Had this problem. Found out the reason was that I had a package.json file in my home folder that node used by default and it messed things up. Had to delete ~/package.json file and problem was solved.
