Vscode-ng-language-service: Language Service not working

[jtsom]

Trying to edit some text, and it looks like the language service isn't doing anything - not syntax checking, not providing popup completion. I don't see any errors in the console log. This is with the latest VSCode Insiders, and the latest Angular Language service extension. Is it dead?

[jtsom]

A small update. I have one project where it seems to work, but more than one where it doesn't. I have noticed in the project where it works (shows popup info while editing), in the Output window, the "getHoverAt" value is > 0. The projects where it does not work, the "getHoverAt" value is always 0ms

I'm also encountering the same issue, working in one project and not in another. I've also gone through and made sure all angular related packages were the same as the working project, but that doesn't seem to help.
I've also gone through tsconfig.json in both projects, but they are identical.

And right after I post that, I seem to have found it.
Doesn't look like this plugin plays well with typescript 2.6. If you revert back to typescript 2.5.3 it seems to be working again.

[jtsom]

Which is a shame, since Angular and the CLI are touting TS 2.6 compatibility with their latest release.

Same here. Had to revert Typescript to 2.5.3.

220 Should fix this issue.

You can work around this issue by removing the @angular/language-service installed in the project directory.

This reason this is failing is that two versions of typescript are being loaded, one from the extensions direction, one from the projects directory. There should only be one copy of typescript in the service and #220 address this.

By removing @angular/language-service you fall back to the version of the language service in the extension that will load the same version of typescript used by the rest of the service.

@chuckjaz that didn't seem to work on my projects.

@chuckjaz chuckjaz Thank you. By removing @angular/language-service worked for me.

I would like to know that if I uninstall the angular language service from my package.json it will not affect my project in any way? since I am working in a large development team

Closing this, since original issue was fixed in https://github.com/angular/vscode-ng-language-service/issues/214#issuecomment-359961369
