Mac Terminal重新启动后无法运行大多数命令 [英] Mac Terminal can't run most commands after restarting it

问题描述

我正在使用Mac.我有一个自定义的终端zsh，一段时间没问题.但是，当我重新启动计算机后，它的行为开始有所不同:

I am using a mac. I have a customised terminal zsh, and it was fine for a while. But after I restarted my computer, it started to behave differently:

• 终端停止运行诸如rake或rails的命令.

• 我已经使用rails创建了应用程序，但是现在使用rails -v这样的rails命令可以使我做到这一点:

• The terminal stopped running commands such as rake or rails.

• I have already created applications using rails, but using a rails command like rails -v now gives me this:

Rails is not currently installed on this system. To get the latest version, simply type:

用于显示波浪号~而不是我的用户名的终端，该终端也已停止.现在，它将显示完整的用户名:

The terminal used to display a tilde ~ instead of my username and that has also stopped. It now displays the full username:

Gustaves-MacBook-Air% $ sudo gem install rails

我什至不知道为什么它不起作用，以及为什么重启计算机会破坏它，即使我之前已经做过.

I have no idea why it doesn't work, and why restarting the computer would break it, even though I've done it before.

我什至无法重新下载rails:

I can't even re-download rails:

$ sudo gem install rails
zsh: command not found: $

因为我很早以前就已经在在线设置之后自定义了我的终端机.

because I have customised my terminal long ago following an online setup.

推荐答案

这是我通过其他人的帮助解决此问题的方法:

Here is how I fixed this problem, through other people's help:

首先，我使用

rm -rf ~/.oh-my-zsh
rm ~/.zshrc

然后我运行以下命令以重新下载zsh

Then I ran the following command to re-download zsh

sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

最后，我用文本编辑器打开了隐藏的.zshrc文件，以添加我需要的插件

Finally, I opened the hidden .zshrc file with text editor to add the plugins i needed

plugins=(
  git
  bundler
  dotenv
  osx
  rake
  rbenv
  ruby
)

重启终端后，一切又恢复正常了

After restarting the terminal, everything was working again
