`pipenv install` 无法正确安装 mysqlclient，而 `pip install` 可以正确安装

Question

brew install mysql-client
mkdir foo && cd foo
export PKG_CONFIG_PATH="/opt/homebrew/opt/mysql-client/lib/pkgconfig"
pipenv install mysqlclient
pipenv run python -c 'import MySQLdb'

退出并出现错误：

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/Users/foo/.local/share/virtualenvs/foo-cSg51m4-/lib/python3.12/site-packages/MySQLdb/__init__.py", line 17, in <module>
    from . import _mysql

和

brew install mysql-client
mkdir foo && cd foo
export PKG_CONFIG_PATH="/opt/homebrew/opt/mysql-client/lib/pkgconfig"
pipenv run pip install mysqlclient
pipenv run python -c 'import MySQLdb'

以零退出。

这是不直观的。为什么

pipenv

的工作方式不同？这是有意的行为吗？

环境：macOS 14.4 arm64 (M3) / Python 3.12 (Homebrew)

我不知道从哪里开始调查。 Python 的依赖管理对我来说太复杂了。

请这样做。

brew install mysql-client

将以下内容添加到您的 shell 配置文件（.zshrc、.bashrc 等）：

export PATH="/opt/homebrew/opt/mysql-client/bin:$PATH"
export LDFLAGS="-L/opt/homebrew/opt/mysql-client/lib"
export CPPFLAGS="-I/opt/homebrew/opt/mysql-client/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/mysql-client/lib/pkgconfig"

然后，获取文件：

source ~/.zshrc  # or source ~/.bashrc

然后，

mkdir foo && cd foo
pipenv --python 3.12
pipenv install mysqlclient
pipenv run python -c 'import MySQLdb'
