python setup.py egg_info错误mysqlclient

Question

我刚刚开始使用Django学习Python，每次似乎都被困在同一地方3天，每次我尝试使用Pycharm在终端中运行以下命令时（是的，我使用的是Mac），我都会收到以下错误消息：

命令：pip install mysqlclient

错误：

Collecting mysqlclient

Complete output from command python setup.py egg_info:

请帮助我了解发生了什么以及如何解决。 首先，我似乎无法运行以下命令：

python manage.py migration（因为我还没有安装mysqlclient）

预先感谢您的协助。

Answer 1

有时在Terminal设置了变量mysql_config ，但在PyCharm未设置，因此这就是为什么您会收到此错误的原因。

解决方案是：

1. 使用以下命令从终端运行PyCharm ：

   /Applications/PyCharm\\ CE.app/Contents/MacOS/pycharm

2. 之后（在PyCharm ）安装所需的软件包（可能它们在您的requirements.txt ，例如mysqlclient ），

3. Close程序，然后re-open

4. 现在应该已经正确安装了所有软件包
