我正在使用mysql-connector 2.1.8一段时间,突然之间,它不再可用。
Could not find a version that satisfies the requirement mysql-connector==2.1.8 (from versions: 2.2.8)
我尝试安装一些较新的版本,例如2.2.5。从字面上工作一次,然后不在服务器上。
最新版本2.2.8给出了这样的错误:

答案 0 :(得分:1)
pip install -U setuptools wheel
较新的软件包版本可能需要setuptools或wheel的较新功能,因此这是--single-version-externally-managed not recognized
的原因
使此类核心软件包保持最新是一件好事,而且它们几乎始终向后兼容。
