It seems to be a permissions issue, you can try using nvm or fnm to manage node.

Or install to the global system via cargo and then execute the rsw command.

# step 1
cargo install rsw

# step 2
rsw -h

Hey @lencx, thanks for the quick response!

I am already using fnm, and rsw is already installed globally.

[hs] rsw --version
rsw 0.7.3
[hs] fnm current
v17.7.1
[hs] yarn

As for permissions, it seems to me that it tries to mkdir in /node_modules/binary-install/bin? That part I still don't fully understand.

rsw is an executable binary implemented by rust, and binary-install/bin is responsible for pulling the binary. I guess it may be caused by this reason. How to fix npm throwing error without sudo

[alaadotsol]

It seems it's a problem with yarn's pnp with rsw. After switching the nodeLinker it worked fine but I had to opt out from pnp :/

Workaround

1 - Create a .yarnrc.yml file
2 - Add this line: nodeLinker: pnpm

Overall you can change the nodeLinker to be anything other than the default pnp.
