缺少正确的命令。 使用RVM之前请确保已安装

Question

I think I install Magnet in Mac and remove better touch tool, then my terminal suddenly gets this:

Last login: Tue Aug 15 16:23:47 on ttys000

ERROR: Missing proper 'which' command. Make sure it is installed before using RVM!

WARNING:
      Errors sourcing '/Users/kenpeter/.rvm/scripts/base'.
      RVM will likely not work as expected.

ERROR: Missing proper 'which' command. Make sure it is installed before using RVM!

WARNING:
      Errors sourcing '/Users/kenpeter/.rvm/scripts/base'.
      RVM will likely not work as expected.

When I type which in terminal, it works.

My question is that, how do I get rid of this warning?

Answer 1

I did yarn global install xxxx . It causes rvm to complain.

yarn global remove xxxx

Fix the issue.

Answer 2

I also received the

Missing proper which command. Make sure it is installed before using RVM

issue when starting my shell.

I use nvm , avn , and rvm and had grunt-cli , karma-cli , typescript , and typings installed globally via yarn when I started getting the error. After removing all of the global packages, the error disappeared.

I cannot reproduce the issue now, go figure. Just thought I'd share in case anyone has a similar issue.

Same issue, but I finally got it working by reinstalling RVM .

I didn't have much luck trying the solutions posted in the issues for this:

Nor with (re)installing RVM through Homebrew . I'm on macOS High Sierra 10.13.4 (17E199). Here are my notes:

# uninstalling RVM: https://stackoverflow.com/a/4747195/539149
rvm implode
# then delete all mentions of RVM in ~/.bashrc ~/.bash_profile ~/.profile ~/.zshrc

# installing RVM: http://usabilityetc.com/articles/ruby-on-mac-os-x-with-rvm/ https://rvm.io/rvm/install

brew tap --repair
curl -sSL https://get.rvm.io | bash -s stable --ruby
# add RVM to bash profile (usually in one of ~/.bashrc ~/.bash_profile ~/.profile ~/.zshrc)
nano ~/.bashrc
###
# Add RVM to PATH for scripting. Make sure this is the last PATH variable change.
export PATH="$PATH:$HOME/.rvm/bin"
# Load RVM into a shell session *as a function*
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
###
# reload shell settings
source ~/.bash_profile

# upgrading RVM: https://rvm.io/rvm/upgrading
rvm get stable

I realize this isn't the greatest solution if you're in the middle of a project that's on fire (or maybe it is?). But I think it's helpful to always have idempotent snippets that you can apply to remedy a situation, then optimize things later.

brew install node为我修复了它，执行\\which时出现一些节点错误。
