TSServer --globalPlugins not working for inferred projects

[mjbvz]

TypeScript Version: 2.5.2

Steps to reproduce
In a folder with no tsconfig or jsconfig and a single ts file

Start the tsserver with --globalPlugins ts-css-plugin --pluginProbeLocations /Users/matb/projects/css-template-plugin

Bug
I don't see the plugin being loaded unless I create an empty tsconfig.json file

@mjbvz I have a tentative fix up at https://github.com/RyanCavanaugh/TypeScript/tree/fix18322 but I'm not sure how to test it. Can you give it a spin or provide some user-side instructions?

[mjbvz]

Try installing this vscode extension: https://github.com/mjbvz/vscode-styled-components-extension by manually installing the vsix from the repo

Make sure you are using VSCode's version of typescript. We currently disable global plugins if you use the workspace versions

@RyanCavanaugh I don't see this working properly in VS Code 1.18 with TS 2.6.1.

To test:

1. In VS Code 1.18, install the vsix from this repo
2. Open a empty folder in VS Code
3. Create a single ts file with the contents:

styled`

`

4. Try requesting completions inside of the template string

I do not see any css completions. However after creating a tsconfig.json—even without setting the plugins—I start seeing the expected css completions

starting from WS2017.3 we use ts-plugin for providing the Angular LS support in WebStorm and the issue also affects us. Rel. https://youtrack.jetbrains.com/issue/WEB-30045
