Hi,

On MacOS in a project using yarn and workspaces, every time i run yarn (install) i have to rebuild mediasoup because of this error :

Error: spawn …/node\_modules/mediasoup/worker/out/Release/mediasoup-worker ENOENT

Then i have to run `npm rebuild mediasoup` to fix this error.

Any idea ?

Thanks

As told in GitHub, no idea about “yarn workspaces”. Can you reproduce the issue using yarn to install the mediasoup-demo project? If so, please describe the steps and I’ll try to reproduce.
