rbenv: `yarn` shim can't seem to find installed `yarn`

I’ve had this problem for a bit. It seems that rbenv can’t seem to figure out where yarn is. I realize it’s a js dependency so i’m not quite sure why rbenv even wants to have a shim for it.

I’m in a directory that is a JS only project - so there is no .ruby-version, i have the following config:

$ rbenv --version
rbenv 1.1.0
$ ruby --version
ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-darwin15]
$ brew list
...
yarn
...
$ which yarn
/Users/jon/.rbenv/shims/yarn
$ yarn -v
rbenv: yarn: command not found
$ brew list yarn
/usr/local/Cellar/yarn/1.2.1/bin/yarn
/usr/local/Cellar/yarn/1.2.1/bin/yarnpkg
/usr/local/Cellar/yarn/1.2.1/libexec/bin/ (5 files)
/usr/local/Cellar/yarn/1.2.1/libexec/lib/ (2 files)
/usr/local/Cellar/yarn/1.2.1/libexec/package.json
$ /usr/local/bin/yarn -v
1.2.1

This has also occurred in ruby project directories where there is a .ruby-version and I’m using yarn for webpack and other stuff.

Any ideas?

The yarn shim was added to rbenv because one of the Ruby versions has, for some reason, a yarn executable. To remove it, do the following in bash:

for ver in $(rbenv whence yarn); do
  RBENV_VERSION="$ver" gem uninstall -ax yarn
  rm -f "$(rbenv prefix "$ver")/bin/yarn"
done
rbenv rehash

# now check the yarn executable again:
which -a yarn

Unless you have some rbenv plugins that I don’t know about.

I faced this problem too and check installed plugins. I removed https://github.com/ianheggie/rbenv-binstubs and solved it.

But I just want to make sure if this is expected. When i run which yarn command in non-ruby / non-bundler directory, it will still point to rbenv shims

Yes, that is expected behavior. You will notice though, that if you run rbenv which yarn, the yarn will be pointed back to your system yarn (if there is one) or otherwise yarn from nenv or similar environment manager.

For what it’s worth, I was able to fix this issue by running rm -rf /Users/$(whoami)/.rbenv/shims/yarn. Don’t know if that’s recommended but I tried everything here and nothing worked.

@akashani62 you have a typo in your comment: it should be .bundle/bin/yarn (without the first slash!).

You can also copy ./bin/yarn to ./bundle/bin/yarn inside your rails app and keep rbenv-binstubs

In my environment, this happens not only rails project directory but anywhere globally.
