Mac OS X issue on install

[cattmallahan]

When I run npm install --global yo, I receive the following response:

npm WARN deprecated @npmcli/move-file@1.1.2: This functionality has been moved to @npmcli/fs
npm WARN deprecated readdir-scoped-modules@1.1.0: This functionality has been moved to @npmcli/fs
npm WARN deprecated @npmcli/move-file@2.0.1: This functionality has been moved to @npmcli/fs

changed 734 packages in 35s

82 packages are looking for funding
run npm fund for details

After that, if I run yo --version, the response is: zsh: command not found: yo

Any help solving this issue is much appreciated!
