"Cannot find name" and other problems with TypeScript-SFC

• I have searched through existing issues
• I have read through docs
• I have read FAQ

Info

• Platform: Win 10
• Vetur version: 0.22.1
• VS Code version: 1.37.0

Problem

Vetur underlines everything and gives errors like Cannot find name all the time.

Reproducible Case

At the moment I’m not sure how to make a reproducible case. The project is closed source and I’m not the author of most of the code. I mostly hope, that someone has seen this behaviour before.

Just encountered this issue as well, same situation as @msamsel

Steps taken to address:

1. renamed File.Vue to File.vue (did not work)
2. created NewFile.vue and copied code from File.vue over
3. deleted File.vue
4. renamed NewFile.vue to File.vue

@ktsn I hope this description will help you track down the error.

Same issue here. The way how I was able to make such error. VSCode: version: 1.47.1 Vetur: 0.24.0 MacOS: 10.15.5

1. Open VSCode and create new file with button in on left file tree:
2. Name file with anything.Vue important part is to start extension with a capital letter.
3. VSCode will start to produce single error on the closing character of </template> tag:
4. Rename file (inside VSCode) to small later extension anything.vue
5. Fully close and open VSCode again
6. Open file with small letter extension.
7. Please notice that Vetur error still see file as test.Vue not test.vue as it is an actual name of the file. It looks like something somewhere is cached.
