代码收藏家 如何解决Python中的”setup.py egg_info did not run successfully”问题
在安装pycurl库时遇到了这个问题：
pip install pycurl
Collecting pycurl
Using cached pycurl-7.45.2.tar.gz (234 kB)
Preparing metadata (setup.py) ... error
error: subprocess-exited-with-error
× python setup.py egg_info did not run successfully.
│ exit code: 10
╰─> [1 lines of output]
Please specify --curl-dir=/path/to/built/libcurl
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed
× Encountered error while generating package metadata.
╰─> See above for output.
note: This is an issue with the package mentioned above, not pip.
hint: See above for details. 在搜索之后猜测是不是版本不匹配问题，先升级了pip包：
pip install --upgrade pip
pip install --upgrade setuptools
pip install ez_setup再重新pip install pycurl还是不行，又尝试了以下命令：
pip install pycurl==7.43.0.5 -i "https://mirrors.bfsu.edu.cn/pypi/web/simple/"这次可以了，成功安装pycurl库之后运行结果是这样的：
