Can you help me finding a repro? Try it on some public vue projects like https://github.com/vuejs/vue-hackernews-2.0 or https://github.com/vuejs-templates/webpack and see if the server crashes? If not, can you try to put some code from your codebase to a template project and manage to crash vetur's Language Server?

This is what @The-Smallest did and was extremely helpful for me to fix the previous crash:

It's crashing for me too on startup, let me see if I can reproduce.

It's happening to me as well. I just created a stock asp.net core web api project using the yeoman generator and as soon as I opened the project it it started crashing.

npm install -g yo bower
npm install -g [email protected]
yo aspnet

@octref
I find the crashed reason.
If in a vue file script tag write import Vue, that will cause crash.
writeimport vue do not cause crash.

@jing2si

Thanks! I'm able to repro it. Will look into a fix soon.

[sandersn]

It's because vetur 0.6 inserts a hidden import Vue from 'vue' for you. I forgot that people might still want to write it explicitly. In that case, it should not insert a hidden one.

[octref]

@jing2si Thanks for the repro.

For people having this problem, 0.6.2 is published with @sandersn's fix. Please give it a try.
@jing2si's case is resolved by 0.6.2 at least.

0.6.2 fixed it for me too, thanks! 👍

It seems to be fixed but I am experiencing abnormal performance issues. For example, if auto-complete is triggered it shows a loading sign which stays for some seconds until the auto-complete dialog shows up. Is anyone else experiencing this?

It used to be really fast (Instant completion-info) for my project which hasn't changed in a few weeks.

Also is it normal that the vetur server process uses like 1-2 GiB ram?

[octref]

@cynecx That's not normal. I'm looking into that in #131.
