When you install a package globablly either with yarn (or npm)
$ yarn global add vercel
It places the binaries for that package in the bin
directory of your package
manager's configured path prefix.
The absolute path to this bin
directory can be found with:
$ yarn global bin
/Users/jbranchaud/.asdf/installs/nodejs/15.4.0/.npm/bin
You can ensure that everything located in that bin
directory is on your
shell's path by adding the following line to your shell's config file (e.g.
.bashrc
or .zshrc
).
export PATH="$PATH:$(yarn global bin)"
Once you've updated your shell config, make sure you source the file or restart your shell.
