如何在 mac 上使用 pipenv？

Question

通过pip(pip install pipenv)安装时，在zsh上shell找不到命令pipenv。

如果通过brew安装：brew install pipenv，然后运行 pipenv shell，出现错误

没有路径命名 /use/bin/zsh。为什么不稳定？

shell路径是

echo $SHELL
/bin/zsh

你真的在问两个问题。我将在下面的单独部分中回答每个问题：

如何修复该错误

The command was not found or was not executable: /use/bin/zsh.

看起来像 in your .env file，你有 PIPENV_SHELL=/use/bin/zsh。那是不正确的。相反，它应该是

PIPENV_SHELL=/bin/zsh

甚至只是

PIPENV_SHELL=zsh

或者您也可以将其删除。然后 pipenv shell 将简单地使用与您调用它相同的 shell。

如何在 macOS

上正确安装 pipenv

在 macOS 上安装 pipenv 的正确方法有点复杂，但如果您不想运行在升级 [=53] 时遇到问题，这是唯一的方法=]版本：

撤消到目前为止所做的操作：

% pip uninstall pipenv
% brew uninstall pipenv

将以下内容添加到您的 .zshrc 文件中：

eval "$( brew shellenv )"
export PYENV_VERSION=3.9.5  # Set your preferred Python version.
export PYENV_ROOT=~/.pyenv
export PIPX_BIN_DIR=~/.local/bin
export -U PATH path         # -U eliminates duplicates
path=( 
    $PIPX_BIN_DIR
    $PYENV_ROOT/{bin,shims} 
    $path
)

打开一个新的终端window（所以上面的更改生效）并执行以下操作：

% brew install pyenv
% pyenv install $PYENV_VERSION # Install your preferred Python.
% pyenv global $PYENV_VERSION  # Make it your default Python.
% pip install -U pip           # Update pip.
% pip install -U --user pipx   # Install pipx into ~/.local/bin
% pipx install pipenv          # pipx is like brew but for Python.

将以下内容添加到您的 .zshrc 文件中：

eval "$( pyenv init - )"
eval "$( pip completion --zsh )"
eval "$( register-python-argcomplete pipx )"
eval "$( pipenv --completion )"

重新启动您的 shell（通过键入 exec zsh 或打开一个新终端 window）以使上述生效。
