Visual Studio cannot find Typescript declaration file 'source-map' #449
Description
Activity
For me, this issue was occurring because @babel/generator still uses source-map@^0.5.0. They actually bumped the version two years ago, but then reverted it due to a regression (rather than fixing their codebase to work with the new version of source-map).
See: babel/babel#12025
If you run
npm ls source-mapyou can see the tree of which packages are dependent upon it. Here's what mine looks like:└─┬ [email protected] ├─┬ [email protected] │ └─┬ @babel/[email protected] │ ├─┬ @babel/[email protected] │ │ └── [email protected] deduped │ └── [email protected] ├─┬ [email protected] │ ├─┬ [email protected] │ │ └─┬ @babel/[email protected] │ │ ├─┬ @babel/[email protected] │ │ │ └── [email protected] deduped │ │ └── [email protected] │ └─┬ [email protected] │ └── [email protected] └─┬ [email protected] └── [email protected]Maybe the fix can be backported into ^0.5 and ^0.6. I think this repo would need to create a branch for each of those minor versions before I could create a PR for them though.
I'm getting this error in Visual Studio 2019 :
The cause of this error seems to be this line in package.json:
"typings": "source-map",If i change it to
"typings": "source-map.d.ts",then everythings works fine.
