Homebrew installs nvm but nvm can't be found a

2019-03-08 02:59发布

I'm using homebrew and oh-my-zsh on a fresh OSX 10.10.1 install. I got nvm via homebrew and then attempted to run it but says - zsh: command not found: nvm

Any idea what the problem is? I was able to install and use git just fine...

Did you follow the instructions listed in the caveats?

[~] brew info nvm
nvm: stable 0.20.0, HEAD
https://github.com/creationix/nvm
Not installed
From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/nvm.rb
==> Caveats
Add the following to $HOME/.bashrc, $HOME/.zshrc, or your shell's
equivalent configuration file:

  source $(brew --prefix nvm)/nvm.sh

Node installs will be lost upon upgrading nvm. Add the following above
the source line to move install location and prevent this:

  export NVM_DIR=~/.nvm

Without the extra config it doesn't look like it will find NVM by default..

There are TWO things you need to do. Follow the caveats shown after installing nvm via brew, and THEN you need to activate/reload the .bash_profile changes.

  1. Run brew install nvm
  2. Follow caveats shown in console, mine were as follows, yours MAY be different!:

Add the following to ~/.bash_profile or your desired shell configuration file:

export NVM_DIR="$HOME/.nvm"
. "$(brew --prefix nvm)/nvm.sh"
  1. Run . ~/.bash_profile to apply the changes you made to your .bash_profile file

The reason you would need to reload your bash profiles or any other bash files might be because the command nvm may not be a program but a function that is defined and can only be used if the corresponding bash file is sourced.

On a system that I checked

which nvm 

does not work but

nvm list

does. This means that you can use the word "nvm" to invoke something. That something isn't a program. In the current case, it is a function which can be verified by

typeset -F | grep -P ' nvm$'

which outputs

declare -F nvm

which means nvm is a function, whose body can be inspected by doing

type -F nvm

One possibility if brew was used is that the nvm may be unlinked, especially if it was installed by another MAC OS user.

In this case, execute:

brew link nvm
