每当我尝试使用pip安装任何软件包时,我收到此导入错误:
guru@guru-notebook:~$ pip3 install numpy
Traceback (most recent call last):
File "/usr/bin/pip3", line 9, in <module>
from pip import main
ImportError: cannot import name 'main'
guru@guru-notebook:~$ cat `which pip3`
#!/usr/bin/python3
# GENERATED BY DEBIAN
import sys
# Run the main entry point, similarly to how setuptools does it, but because
# we didn't install the actual entry point from setup.py, don't use the
# pkg_resources API.
from pip import main
if __name__ == '__main__':
sys.exit(main())
它之前工作正常,我不知道为什么它会抛出这个错误.我搜索了这个错误,但找不到任何解决方法.
如果您需要任何进一步的细节,请告诉我,我会更新我的问题.
我安装了最新的python(2.7.9)捆绑了pip和setuptools for windows 32-bit.我已经尝试重新安装pip,但问题仍然存在.
这是pip --version在Administrator cmd中运行后的错误:
Traceback (most recent call last):
File "D:\Python\lib\runpy.py", line 162, in _run_module_as_main
"__main__", fname, loader, pkg_name)
File "D:\Python\lib\runpy.py", line 72, in _run_code
exec code in run_globals
File "D:\Python\Scripts\pip.exe\__main__.py", line 5, in <module>
ImportError: cannot import name main
Pip总是失败,即使我做pip install dedupe或pip install --trusted-host pypi.python.org dedupe
无论如何,输出总是相同的:

重试(重试(总计= 4,连接=无,读取=无,重定向=无,状态=无))连接被"SSLError"破坏后(SSLError(1,'[SSL:CERTIFICATE_VERIFY_FAILED]证书验证失败(_ssl.c: 777)'),)':/ simple/dedupe/

所以我卸载了anaconda并重新安装了它.一样.
你认为问题是我的_ssl.c文件(我不知道它在哪里)必须是腐败的还是什么？为什么pip需要引用,如果我告诉它绕过ssl验证呢？
以前我曾经通过pip安装软件包，但是现在我试图使用pip安装Python库，但遇到SSL错误：
