RVM / rbenv / 终端 $PATH 错误：(eval):18: `PATH=/usr/local/opt/...' 附近的解析错误

Question

I noticed the following error in my Mac (Monterey version 12.4) terminal upon opening it today:

(eval):18: parse error near `PATH=/usr/local/opt/...'

I suspected that it was related to my installation and removal of Ruby Version Manager (RVM - https://rvm.io/ ) last week. When I tried using RVM to install Ruby 2.6.1, the installation failed, and upon doing some research, it looked like RVM has issues with install older versions of Ruby on Macs. Therefore, I removed RVM and installed rbenv instead, which worked. Anyway, to uninstall RVM, I ran:

rvm implode

I also removed an RVM line from my bash_profile. This was all done last week.

Upon seeing this new error in my terminal, I ran echo $PATH , which output this:

/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/francoortega/.rvm/bin

I'm guessing that the .rvm part of this $PATH may be part of the problem.

Next I ran open ~/.bash_profile and open ~/.bashrc , which had this info:

bash_profile

[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*eval "$(rbenv init -)"

bashrc

# Add RVM to PATH for scripting. Make sure this is the last PATH variable change.
export PATH="$PATH:$HOME/.rvm/bin"

I tried deleting the rvm info from these files, but that didn't have any effect, so I undid those deletions. Also, it seemed odd that the bash_profile had a line that include rvm and rbenv info

Then, I ran open ~/.zshrc , which output this:

# Add RVM to PATH for scripting. Make sure this is the last PATH variable change.
export PATH="$PATH:$HOME/.rvm/bin"

eval "$(rbenv init - zsh)"export PATH="/usr/local/opt/ruby/bin:/usr/local/lib/ruby/gems/2.6.10/bin:$PATH"

I tried deleting the .rvm line, but that had no effect, so I undid that deletion. Then, surprisingly, when I deleted the rbenv file, this removed the terminal error.

1. However, I don't want to delete rbenv, so I'm not sure what would be the proper way to fix this error.

2. Additionally, I wasn't able to find the path listed in the error ( /usr/local/opt/ ) either.

3. And since I no longer have RVM, should I delete the rvm lines from the bash_profile bashrc, and .zshrc files?

Answer 1

It looks like the following steps solved my issue:

1. Removed this line from .zshrc:

eval "$(rbenv init - zsh)"export PATH="/usr/local/opt/ruby/bin:/usr/local/lib/ruby/gems/2.6.10/bin:$PATH"

2. Removed this line from .bash_profile:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*eval "$(rbenv init -)"

3. Removed these two lines from .bashrc and .zshrc:

# Add RVM to PATH for scripting. Make sure this is the last PATH variable change.
export PATH="$PATH:$HOME/.rvm/bin"

My .bashrc and .zshrc files are now empty, and my .bash_profile only contains:

[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile

My terminal now open without any error message.

Also, I found it strange that the line in my .bash_profile mentioned both rvm and rbenv (see original post above), but reading the rbenv docs, it turns out that I was supposed to remove rvm before installing rbenv, so maybe having rvm on my machine when I install rbenv is what led to this mashup.

Finally, as I mentioned in my original post, I had already removed rvm, but today I removed rbenv with the following two commands (it had been installed via Homebrew):

rm -rf `rbenv root`
brew uninstall rbenv
