当我尝试使用oursql在虚拟环境下安装pip install oursql时出现以下错误：

然后我使用MySQL C++ connectors安装了sudo apt-get install libmysqlcppconn-dev，但仍然出现错误。
所以，我尝试了sudo pip install oursql并获得了以下输出：
The directory '/home/raghav/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

出了什么问题？我无法找到。

the directory '/home/raghav/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
我认为您使用sudo pip在virtualenv中安装了一些库。所以现在一些文件归root用户所有，你的用户无法在那里写。你永远不应该以root身份使用virtualenv。
如果您有一个requirements.txt文件，我认为最简单的方法是创建一个新的virtualenv并重新安装所有内容。如果您不想/不能这样做，请尝试使用chown

您没有安装python开发库。首先尝试安装它，然后运行pip。
sudo apt-get install python2.7-dev
答案 2 :(得分：0)
试试这个 -
$ sudo apt-get install libmysqlclient-dev
$ sudo pip install oursql
