pyenv 在 macos 上给出 shopt 命令未找到错误 [英] pyenv giving shopt command not found error on macos

问题描述

一段时间以来，我一直在使用 pyenv 来管理我的 mac 上的 python 版本和虚拟环境.最近我重新安装了 pyenv，从那以后在我尝试运行的每个 pyenv 命令上，我都收到以下错误

/usr/local/bin/pyenv:94:找不到命令:shopt

我的默认 shell 是最新的 MacOS 的默认 shell，即 zsh.
在搜索修复程序时，我发现它与 bash 干扰 zsh 有关系.
我的默认shell是settings中的zsh，~/.bash_profile的内容，/etc/profile &/etc/bashrc 都被注释掉了，但我仍然有这个问题.
我的操作系统版本是:10.15.4.
我也尝试重新安装 pyenv，但我遇到了同样的错误.

我无法运行任何 pyenv 相关命令.

根据文档，我的 .zshrc 中已经有这些行，但是正如您所看到的，即使这样也运行命令 pyenv root 并且这给了我相同的shopt 错误.

export PYENV_ROOT="$HOME/.pyenv"export PATH="$PYENV_ROOT/bin:$(pyenv root)/shims:$(pyenv root)/completions/pyenv.zsh:$PATH"

解决方案

根据您的信息和评论，您的问题似乎有 3 个原因:

1. pyenv 是一个 bash(和 bash-only)脚本，带有一个 shebang 行 #!/usr/bin/envbash
2. /usr/local/bin 在你的 PATH 中出现在 /usr/bin 或 /bin 之前，所以其中的可执行文件首先被选中通过 /usr/bin/env(期望的行为，尤其是在使用 homebrew 时)
3. /usr/local/bin/bash 符号链接到 /bin/zsh!?!

所以最后你用 zsh 运行 pyenv，虽然它是 bash 的替代品，但不知道shopt，因此窒息.我不知道为什么符号链接到位，但它不应该，因为 zsh 不是 bash 的完全兼容的替代品.

我建议

1. (如果您使用的是自制软件)
   检查您是否通过 homebrew 安装了 bash(后来不知何故被 zsh 的符号链接替换):

   # 只显示顶级包(直接安装)冲泡叶子# 显示带有依赖树的*所有*包brew deps --tree --installed

   如果不再需要，则卸载 bash(应该然后删除 /usr/local/bin/bash).

2. 删除或至少重命名罪魁祸首:

   mv/usr/local/bin/bash/usr/local/bin/bash_link_to_zsh

   或者，如果某些程序需要 /usr/local/bin/bash 到位，只需让它指向 /bin/bash.

I have been using pyenv for managing python versions and virtual environments on my mac for some time now. Recently I reinstalled pyenv and since then on every pyenv command I try to run, I get the following error

/usr/local/bin/pyenv:94: command not found: shopt

My default shell is the latest MacOS's default shell i.e. zsh.
On searching for the fix, I found out it has something to do with bash interfering with the zsh.
My default shell is zsh in settings, the contents of ~/.bash_profile, /etc/profile & /etc/bashrc are all commented out but I am still having the issue.
My OS Verion is: 10.15.4.
I tried reinstalling pyenv as well but I am getting the same error.

I am unable to run ANY pyenv related command.

Edit 1

I already have these lines in my .zshrc as per the documentation, but as you can see, even this run a command pyenv root and this gives me the same shopt error.

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$(pyenv root)/shims:$(pyenv root)/completions/pyenv.zsh:$PATH"

Run env and add the output in your question

解决方案

According to your info and comments it seems your issue has 3 causes working hand in hand:

1. pyenv is a bash (and bash-only) script with a shebang line #!/usr/bin/env bash
2. /usr/local/bin comes before /usr/bin or /bin in your PATH, so executables therein are picked up first by /usr/bin/env (desired behaviour, especially when using homebrew)
3. /usr/local/bin/bash is symlinked to /bin/zsh!?!

So in the end you are running pyenv with zsh, which, albeit being a close replacement for bash, doesn't know about shopt and therefore chokes. I don't know why the symlink is in place, but it shouldn't, because zsh is not a fully compatible drop-in replacement for bash.

I'd suggest to

1. (in case you are using homebrew)
   Check if you have/had bash installed through homebrew (which was later somehow replaced by a symlink to zsh):

   # shows only top-level packages (directly installed)
   brew leaves        
   
   # shows *all* packages with dependency tree
   brew deps --tree --installed
   

   And uninstall bash if not required anymore (which should then remove /usr/local/bin/bash).

2. Either delete or at least rename the culprit:

   mv /usr/local/bin/bash /usr/local/bin/bash_link_to_zsh

   Or, if some program requires /usr/local/bin/bash to be in place, just have it point to /bin/bash.
