这是错误。我一直试图找出错误。我做了一些搜索，但没有用。我正在运行Fedora 22.我检查了是否可以安装MySQL。但是已安装mysql-devel和mysql-libs。请帮忙。

编辑：我试过了：

easy_install mysql-connector==2.1.3

它有效。但为什么pip失败？

Answer 1

您的setuptools版本可能已过时。尝试升级pip：

pip install --upgrade setuptools

您可以在此主题中找到有关此错误的信息：

Answer 2

我认为这是一个老问题，但错误似乎在每次mysql-connector升级时重复，我从以下位置下载源代码：

https://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-2.1.6.tar.gz

解压缩并进入该文件夹并应用：

sudo python setup.py install

恕我直言，我认为问题，至少在我使用macOS的情况下，是最近安装的Xcode。

pip install mysql-connector == 2.1.3失败
