Vetur: Vetur 0.17.0 syntax highlighting not working

[davepile]

Windows 10 x64
VSCode 1.32.3

Vue file syntax highlighting stopped working yesterday. I played around uninstalling and reinstalling Vetur current and previous versions and got it working.

Assume it is the 2 day old release of 0.17.0.
0.16.2 works without issue.

I am new to VSCode and plugins, so the auto update extensions and reload features confused me as to which version was actually running.

When I install 0.16.0 and do a reload, syntax highlighting works. Then I notice Vetur auto installs
0.17.0 but requires a reload, so syntax highlighting doesn't continued working until I close and re-open VSCode and 0.17.0 becomes active.

I have disabled auto updates for extensions

That sounds like an issue with VS Code's extension upgrading. You should report to https://github.com/microsoft/vscode. fyi @sandy081

I am curious what makes you say it is a VSCode upgrade issue when installation of 0.16.2 works, yet after install 0.17.0 it doesn't work. The install/ uninstall seem to be working fine.

Is this summary accurate for you?

• Installing 0.16 straight works
• Upgrading from 0.16 to 0.17 doesn't work
• Installing 0.17 straight works

@davepile
my colleague had same issue, and he fixed it with the following steps:

1. uninstall vue-snippets extension (or any other possibley related extensions)
2. uninstall vetur
3. reinstall vetur
4. close and reopen VScode

You could try disabling other extensions, before you uninstall it. I hope this works for you.

@octref I believe the third step 0.17 did not work, but I did a lot of install/ uninstall/ upgrade so I think I did this step and it did not work but cannot say for certain.

I have just uninstalled and re-installed (now 0.17.1) and that works. I guess we'll never know.

Thanks for the help. Thanks @TakahiRoyte.

They contribute a language / grammar *.vue which conflicts with Vetur, so it won't work.

I updated the FAQ.
