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

[presto-wei]

first of all , I have globally instanlled eslint by npm

[dbaeumer]

@iosky anything special in the ESLint Output channel. What happens if you execute eslint from a terminal on the same file / project. Does it work correctly ?

[presto-wei]

this has been tested ,and it works.

[dbaeumer]

Anything in the ESLint Output Channel (e.g. OUTPUT tab -> ESLint drop down). Can you provide the sample as a GitHub repository I can clone so that I can investigate ?

Does ESLint work for you on other projects or does it always fail ?

[presto-wei]

once the vscode is restarted, it will report this problem, but in terminal, eslint works normally

[presto-wei]

during this time, I also completely uninstall be vscode and then reinstall it, but it will also report this error.

[presto-wei]

this is my a test library for my local installation of eslint, but it's still wrong.
git@github.com:iosky/eslintTest.git

[dbaeumer]

The link in this comment #437 (comment) doesn't point to a valid GitHub repository. Can you please provide the correct link.

And is there anything in the ESLint Output Channel.

[presto-wei]

eslint does not run, so nothing appears in the output box

[presto-wei]

git@github.com:iosky/eslintTest.git
isn't this repository ok ?

[dbaeumer]

Now the link doesn't work. The correct one is https://github.com/iosky/eslintTest :-)

[dbaeumer]

The repository doesn't work for me. It contains a references to

[presto-wei]

Now, the repository is work, but eslint doesn't run in vscode
https://github.com/iosky/eslintTest.git

[dbaeumer]

I cloned the repository again and I still get

[dbaeumer]

After removing the eslint options from the setting everything works for me as expected:

[dbaeumer]

Is there anything in the ESLint Output Channel? And can you enable logging to see when the server crashes "eslint.trace.server": "verbose"

[presto-wei]

I set, but no thing in the output channel, I wonder if my local setting affects eslint server. Is there a requirement on node's path setting? I have changed the global installation path of node before

[coyle5280]

I am having the same issue with vs code and eslint. Eslint server crashes everytime I open VS code. I have added eslint.trace.server": "verbose to settings and unfortunately when the eslint server crashes the output channel also disappears. I have no other eslint options in settings. I have tried uninstalling and reinstalling eslint, vscode, eslint vs code extension. Same error appears every time. This problem surfaced very recently. Was working only a few days ago. .eslintrc.js is working for others in VS Code with same versions. Any help would be appreciated.

[dbaeumer]

I created a special vsix that disables the disposing of the output channel to see if we get better tracing when the server crashes. To install the vsix do the following:

• download this zip:
  vscode-eslint-1.4.8.zip
• change the extension to vsix
• uninstall the eslint extension
• install the eslint extension from the downloaded vsix. To do so open VS Code and the F1 > Install from VSIX
• provide me with the output when the server crashes.

@coyle5280 can you think of anything that makes your machine different to others. As said I am not able to reproduce this.

[presto-wei]

I did，But，when the server crashes， there is nothing in the output panel except the error alert

[dbaeumer]

@iosky strange. Could you do the following: before opening the JS file open the developer console via Help > Toggle Developer Tools. Then open the JS file that makes the server crash. Is there anything in the console of the developer tools ?

[presto-wei]

[coyle5280]

@dbaeumer I can't think of anything that I have changed or installed over the last few days that would make my machine different from my colleagues.
Here is the output from ESlisnt:

My console output is the same as @iosky

Here is a little info on what I am running. Maybe it will help maybe not...

ESLint Version: v4.19.1
Global node version: v8.11.1

[rheng001]

I am having the same problem with the same setup as @iosky and @coyle5280

[dbaeumer]

Actually I have no idea why this is happening. Could someone of you try to debug this ? Do the following:

• clone this repository
• cd into the directory
• npm install
• npm run compile
• open the workspace with VS Code.
• go to client\src\extension.ts
• on line 361 change inspect to inspect-brk
• Run Task > npm run watch:client
• open debug panel and select Lanuch Extension. Press the run button
• in the start Code instance select the workspace the makes the eslint server crash
• go back to the Code instance that contains the eslint code
• debug panel
• select Attach to server and press the run button. This should break in electronForkStart.js
• open server/out/eslintServer.js
• set a breakpoint at the top of the file
• press continue
• step through the eslintServer.js

I guess it bails out pretty early on one of the require calls. Let me know where it happens.

[coyle5280]

@dbaeumer Sorry I have not been able to get to those steps yet but I will soon. Hopefully tomorrow the 11th. Will post back then. Thanks!

[coyle5280]

@dbaeumer I followed the steps you have listed above and was able to step through the file eslintServer.js. Unfortunately I did not come across any errors. Everything seems to proceed correctly as I step through the program. Any ideas? Or anything that I need to look for that i might be missing.

[dbaeumer]

@coyle5280 thanks for doing this. That indicates that it doesn't fail when the initial modules are loaded. Can you try setting a breakpiont at line 244 (content library = require(path);) and see if something wired happens there?

[dbaeumer]

And do you have any special firewall or proxy setup which might terminate the connection between the extension host and the ESLint server?

I got the same problem with that while I update my vscode-insider version coincidentally.
I try to install eslint locally but still crash like this.

my setting refer eslint:

my vscode info:

ESLint Version: v4.19.1
Global npm version: v6.1.0
Global yarn version: v1.8.0-20180525.0727
Global node version: v10.3.0

[dbaeumer]

@nic611 do I understand you correctly:

• the workspace worked before
• you updated VS Code
• now ESLint always crashes when you open it on that workspace

[nic611]

@dbaeumer yes, but only happened when I work with vscode (win), not happened in mac.

[dbaeumer]

@nic611 would you be able to share the project with me, best in a cloneable GitHub repository.

[nic611]

@dbaeumer I try it in vscode stable version, no problem with that. So I guess the insider version cause that.Hope it will be sovled soon(^_^).

[dbaeumer]

@nic611 since everything works for me without problems in the insider and the ESLint extension is independent of insider / stable I would be still interested in being able to reproduce this. Any chance you could share your code.

[majesnix]

I also got this problem.

I had a pair programming / debugging session with @coyle5280 last night (thanks again for doing this with me) and we were able to track this down. The ESLint server process basically crashes in the native npm module child_process when the server calls spwanSync. I have no idea yet why this is happening on your machines (since it doesn't on most of the others) but I will prepare a small test program to see if we can get more output about why this is happening.

[dbaeumer]

Attached a new version of the eslint extension. Follow the steps from here #437 (comment) on how to install it. Can all of you give it a try and let me know if ESLint works for you again:

vscode-eslint-1.4.11.zip

[majesnix]

Works for me 👍

[nic611]

it works!! Thanks a lot @dbaeumer 👍

[dbaeumer]

Great to hear that this fixes your problem. Will release a new version this week.

[coyle5280]

@dbaeumer Working here again.....thanks!!

[dbaeumer]

@coyle5280 thank you for helping me to track this down.

[joshunger]

@dbaeumer what version is this fixed in? I'm seeing this in 1.4.12. 😢

[dbaeumer]

My fix is in 1.4.12

Can you enable tracing to see if the server crashes at a comparable location for you. Set "eslint.trace.server": "verbose" and provide me with the content of the ESLint output channel.

[dbaeumer]

Additional question: are you using npm or yarn?

[joshunger]

I'm using yarn. If you want me to create a separate issue please let me know. Thanks.

@joshunger actually the server crashes at a different location for you. Would you be willing to debug this since I am not able to reproduce this.

[joshunger]

Yes you bet where can I find debugging instructions? Contributing.md?

[dbaeumer]

Thanks. Here are the instructions:

• clone this repository
• cd into the directory
• npm install
• npm run compile
• open the workspace with VS Code.
• go to client\src\extension.ts
• on line 340 change inspect to inspect-brk
• Run Task > npm run watch:client
• open debug panel and select Lanuch Extension. Press the run button
• in the started Code instance select the workspace that makes the eslint server crash
• go back to the Code instance that contains the eslint code
• debug panel
• select Attach to server and press the run button. This should break in electronForkStart.js
• open server/out/eslintServer.js
• set a breakpoint at the top of the file
• press continue
• open server\node_modules\vscode-languageserver\lib\files.js
• set a breakpoint at line 133
• press run
• now step through the code

Let me know where the process actually crashes.

When I select Attach to server and press the run button I see the following dialog -

That is strange. Did you see the server crash output before connecting.
