问题描述
今天在使用以下命令时,出现了奇怪的错误:
pip install -e .
错误如下:
Directory '.' is not installable. File 'setup.py' not found.
You are using pip version 9.0.1, however version 23.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
通过查找资料及阅读错误说明,猜测是pip版本过低所致。
按照错误提示运行
python -m pip install --upgrade pip
出现了以下错误,似乎是镜像网站上没有找到合适的下载源。
Cache entry deserialization failed, entry ignored
Could not fetch URL https://pypi.tuna.tsinghua.edu.cn/simple/pip/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:748) - skipping
解决方案
换个下载源继续更新pip:
python -m pip install --upgrade pip -i https://pypi.douban.com/simple
成功安装!
可用以下命令查看当前pip版本:
pip -V
