The ESLint server crashed 5 times in the last 3 minutes. The server will not be restarted.

I got this message "The ESLint server crashed 5 times in the last 3 minutes. The server will not be restarted." on .jsx file save.
There is no explanation why was it crashed 5 times and how to fix this issue.

Is there any way to understand how to fix this issue and see more explicit error?

Some details:

@artyomtrityak do you have a repository I can clone that shows the behavior. Usually when crashing the client doesn't have a lot of information why.

I was able to reproduce a case where a eslint plugin call process.exit() which in the case of the server shutdowns the server. It was basically a misconfiguration of the eslint / eslint plugin setup.

I added code on the server that detects that case and shows a corresponding message to the user.

See #114.

I will keep this issue open until a new version of ESLint is publish to see if the exit is really causing this.

Ok not I can see the ERROR in output:
Error: Cannot find module 'estraverse-fb'

After installing it globally next error appears:

TypeError: Cannot read property 'visitClass' of undefined
at monkeypatch (/usr/local/lib/node_modules/babel-eslint/index.js:199:40)

Workaround: Upgrade babel-eslint (babel/babel-eslint#243)

@abalmus good to see that you get better error messages now. At the end there is little the eslint extension can do if the eslint library has problems with a certain setup. What is always a good thing to do is to run eslint from the command line to see if it works.

Any objections to close this issue.

[abalmus]

Yeah good point, thank you! I think this one can be closed.

[dbaeumer]

Closing.
