缺少适当的命令。在使用RVM之前确保已安装它

Question

我想我在Mac上安装磁铁并删除更好的触控工具，然后我的终端突然得到这个：

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.

当我在终端输入哪个时，它可以工作。

我的问题是，如何摆脱这种警告？

Answer 1

我做了yarn global install xxxx。它导致rvm抱怨。

yarn global remove xxxx

解决问题。

参考：

https://github.com/yarnpkg/yarn/issues/2064

Answer 2

我也收到了

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

启动我的shell时出现问题。

我使用nvm，avn和rvm并且当我开始收到错误时，通过grunt-cli在全球安装了karma-cli，typescript，typings和yarn。删除所有全局包后，错误消失。

我现在无法重现这个问题。只是想我会分享以防任何人有类似的问题。

Answer 3

同样的问题，但我终于通过重新安装RVM来实现它。

我没有太多运气尝试在这个问题中发布的解决方案：

也没有（重新）通过Homebrew安装RVM。我在macOS High Sierra 10.13.4（17E199）上。这是我的笔记：

# 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

我意识到如果你正处于一个火上浇油的项目中（或许它是？），这不是最好的解决方案。但我认为总是有一些幂等片段是有帮助的，你可以应用这些片段来纠正一种情况，然后再对事物进行优化。

brew install node为我修复了它，我在做\which时遇到了一些节点错误。
