zsh：找不到命令：npm

Question

I have just installed Node and Yarn using the following commands:

brew install node
brew install yarn --without-node

node -v       
v11.8.0

-a node  
node is /usr/local/bin/node

yarn -v       
1.13.0
type -a yarn
yarn is /usr/local/bin/yarn

However, if I write in terminal npm is says "zsh: command not found: npm"

In my: ~/.zshrc I have:

ZSH=$HOME/.oh-my-zsh

# You can change the theme with another one:
#   https://github.com/robbyrussell/oh-my-zsh/wiki/themes
ZSH_THEME="robbyrussell"

# Useful plugins for Rails development with Sublime Text
plugins=(gitfast last-working-dir common-aliases sublime zsh-syntax-highlighting history-substring-search)

# Prevent Homebrew from reporting - https://github.com/Homebrew/brew/blob/master/share/doc/homebrew/Analytics.md
export HOMEBREW_NO_ANALYTICS=1

# Actually load Oh-My-Zsh
source "${ZSH}/oh-my-zsh.sh"
unalias rm # No interactive rm by default (brought by plugins/common-aliases)

# Load rbenv if installed
export PATH="${HOME}/.rbenv/bin:${PATH}"
type -a rbenv > /dev/null && eval "$(rbenv init -)"

# Rails and Ruby uses the local `bin` folder to store binstubs.
# So instead of running `bin/rails` like the doc says, just run `rails`
# Same for `./node_modules/.bin` and nodejs
export PATH="./bin:./node_modules/.bin:${PATH}:/usr/local/sbin"

# Store your own aliases in the ~/.aliases file and load the here.
[[ -f "$HOME/.aliases" ]] && source "$HOME/.aliases"

# Encoding stuff for the terminal
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8

I tried to uninstall and reinstall Node and Yarn using this guide: How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)

But I still get the same error.

Answer 1

It worked for me when I added source ~/.bash_profile at the beginning of my ~/.zshrc and I had to also remove

test -e "${HOME}/.iterm2_shell_integration.bash" && source "${HOME}/.iterm2_shell_integration.bash"

in ~/.bash_profile . This was the shell integration I accidentally installed from iTerm2.

Answer 2

通过完全卸载Node并通过网站（而不是通过终端）安装来解决它

Answer 3

通过运行brew uninstall node并从他们的网站下载安装 .pkg 的最新节点来解决它。

Answer 4

solved by selecting a node version using nvm.

nvm ls

then

nvm use _version_code
