New commands don't completing

[mhalano]

Zsh is unable to complete new commands. Example: If I install (or purge) a package, I need to reload the shell (hit enter, ctrl-c, etc.).

That's a normal thing, not related to oh-my-zsh. The appropriate command to run once you've installed a new command is hash -rf. See http://unix.stackexchange.com/a/2180

[mhalano]

I found the answer via zsh mailing list. 'hash -rf' is still not the
answer. The correct command is:

zstyle ':completion:*' rehash true

Why this option is not defined by default on oh-my-zsh?

[mcornella]

That's a good question, I think it could be set. There could be a performance cost though [1] [2], but for the most part it will be fine.
We could add that line in lib/completion.zsh, care to submit a PR?

[mhalano]

Already send the PR. Please let me know if PR is fine or not... Is my first
pull request for another project. :)

Tested the PR on my machine (Fedora 22), it works as expected! Please pull this request in master.

after i install o-m-z,
zsh:command not found:npm(or node)

[mcornella]

@MightyCreak we decided not to merge it because it could be a significant performance hit on systems with network drives in $PATH, and a setting wouldn't be a good solution since it's a oneline change and it can be added to zshrc as easily.

@Lyuuuu that seems to be a separate issue. If you just installed node or npm, just run rehash to refresh the commands from $PATH. If that's not the case or the solution doesn't work, you might have to change the $PATH in the zshrc file ($HOME/.zshrc). If it worked before have a look at PATH modifications in the rc file for your last shell; this will most commonly be $HOME/.bashrc or $HOME/.bash_profile.
