Installing npm package with prepare script from yarn produces only index.js

I have this sample typescript package with prepare script running tsc: https://github.com/richard-ejem/tspackage

When I install it with npm using npm add git+https://github.com/richard-ejem/tspackage.git#master to a project, node_modules/tspackage/dist contains 4 files as expected:

However, when installed with yarn using yarn add git+https://github.com/richard-ejem/tspackage.git#master, the dist folder contains only index.js.

Am I missing something, or is this a bug in yarn? Is there some possible workaround/other way to build typescript git dependencies on yarn install?

Try add through ssh, yarn add ssh://github.com/richard-ejem/tspackage#master

Don't know why, but it worked for me, yarn -v 1.22.15

Finally found a solution - the trick is to add empty .npmignore file to the repository.

It is probably related to this problem: https://github.com/yarnpkg/yarn/issues/5235#issuecomment-571206092

if there is no .npmignore, npm/yarn removes everything matching .gitignore on install, and in case of yarn, this somehow conflicts with prepare script. It is still weird that dist/index.js is not removed since it is ignored by .gitignore too, however the empty .npmignore solves the problem.
