Info

• Platform: Windows 10

Updating tsc manually (#682 (comment)) with 0.11.7 works fine.

Problem

0.11.8:

No type information:

No hover hints:

0.11.7:

I cannot reproduce.

Can you provide a repro repository?

[KaelWD]

I can prepare one in a couple hours.

Does that still work for you if you use <script Lang="ts"> and export default Vue.extend({?

[HerringtonDarkholme]

It still works. The problem probably is vetur crash. Otherwise in lang="ts" property at least will have any hover tip. And the completion list suggests no single vetur feature is working.

You can see vetur's log in output panel.

[KaelWD]

Nothing in the output panel, but I do see ERR Language client is not ready yet: Error: Language client is not ready yet at LanguageClient.sendNotification in devtools, twice for every keypress.

[KaelWD]

I'm still getting this with 0.12.1, even with all my other extensions disabled.

I get this error a few seconds after opening a .vue file, then the "language client is not ready" if I try to do anything afterwards:

@KaelWD Sorry about that - It seems language server is not started properly for you.

What's the output from Output -> Vue Language Server?

[octref]

Also, would be helpful if you turn on "vetur.trace.server": "verbose" and show me the output from Vue Language Server.

[KaelWD]

Looks like it's working now for some reason, would the 0.12.3 changes have anything to do with that? I'll let you know if it starts breaking again.

[HerringtonDarkholme]

We only removed chokidar.

The probable cause might be chokidar throw an exception that prevents language server from starting.

[KaelWD]

I guess that's fixed it then, I downgraded back to 0.12.1 and it started crashing again.

@octref Output shows vue initialized for the few seconds before the crash, but then the tab switches back to tasks. vetur.trace.server isn't recognised in 0.12.1.

[KaelWD]

This seems to have regressed in 0.12.4

[KaelWD]

I can't tell what the vue language server outputs with trace.server, the log disappears as soon as it crashes

[octref]

Just to make sure the extension source is not corrupted - can you run the command Developer: Reinstall Extensions for Vetur?

[KaelWD]

Done, same problem still. Updating vscode to 1.24.0 with vetur 0.12.5 seems to be working again though.
