pip安装MySQL python，命令"；python setup.py egg“u info”；失败，错误代码为1 MacOS | Python 2.7

我想使用MySQLdb。当我跑的时候

pip install MySQL-python

结果是

JourneydeMacBook-Pro:~ JourneyWoo$ pip install MySQL-python
Collecting MySQL-python

    Complete output from command python setup.py egg_info:

它们都很好用，但当我再试一次时

pip install MySQL-python

它仍然存在问题

我没有从谷歌搜索中得到可以解决我的问题的答案，非常感谢你能帮我解决这个问题。

对于linux用户

首先安装python3开发人员

laptop$sudo apt-get install python3-dev # debian / Ubuntu
laptop$sudo yum install python3-devel # Red Hat / CentOS
laptop$sudo apt-get install mysqlclient

如果您以前在虚拟环境中安装过卸载它，它还会删除MYSQLdb，在我的例子中，MYSQLdb是所有问题的根源。 然后重新安装

   (venv)laptop:~/Desktop/app/$ pip uninstall mysqlclient
    Uninstalling mysqlclient-1.3.13:
     Would remove:
    /usr/local/lib/python3.7/site-packages/MySQLdb/*
    /usr/local/lib/python3.7/site-packages/_mysql.cpython-37m-x86_64-linux-gnu.so
    /usr/local/lib/python3.7/site-packages/_mysql_exceptions.py
    /usr/local/lib/python3.7/site-packages/mysqlclient-1.3.13-py3.7.egg-info   
   Proceed (y/n)? y
   (venv)laptop:~/Desktop/app/$ pip install mysqlclient

更多详细信息

sudo apt get install python dev default libmysqlclient dev#Debian/Ubuntu

运行这个解决了我的问题

尝试在虚拟环境中安装。我仍然无法解决这个问题，所以我必须放弃mysqldb，使用pymysql，它是由“conda install pymysql”安装的。这实际上取决于您如何在本地MAC上安装MYSQL。您是否使用BREW安装了它？如果是的话，你最近升级了吗？我在运行brew update时遇到了类似的问题。如果所有这些都是真的，请告诉我，我可以尝试帮助清理。@johnnygasysna是的，但我已经更新了它，此方法不起作用……您也可以尝试清除pip的缓存，如下所述：

   (venv)laptop:~/Desktop/app/$ pip uninstall mysqlclient
    Uninstalling mysqlclient-1.3.13:
     Would remove:
    /usr/local/lib/python3.7/site-packages/MySQLdb/*
    /usr/local/lib/python3.7/site-packages/_mysql.cpython-37m-x86_64-linux-gnu.so
    /usr/local/lib/python3.7/site-packages/_mysql_exceptions.py
    /usr/local/lib/python3.7/site-packages/mysqlclient-1.3.13-py3.7.egg-info   
   Proceed (y/n)? y
   (venv)laptop:~/Desktop/app/$ pip install mysqlclient
