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\Scripts\pip.exe\__main__.py", line 5, in <module>
ImportError: cannot import name main
我找到了几个关于这个问题的网页,但没有一个解决了我的问题.
即使我做了:
pip show
我明白了:

from pip.vcs import git, mercurial, subversion, …我的最终目标是下载并安装awscli
http://docs.aws.amazon.com/cli/latest/userguide/awscli-install-linux.html
为了实现我的目标,似乎需要python和pip.
通过yum安装python对我来说不起作用,所以我手动下载并安装了python3,如下所示:
wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz
tar xf Python-3.6.1.tar.xz
cd Python-3.6.1.tar.xz
./configure
make
sudo make altinstall
当我做
pip3.6 --version
我明白了:
Traceback (most recent call last):
File "/usr/local/bin/pip3.6", line 7, in <module>
from pip import main
ImportError: cannot import name 'main'
环境: RHEL 6.6通过ssh访问
到底是怎么回事？如何在我的linux机箱上正确安装pip和python3.6？
编辑:
当尝试通过yum安装它失败所以我试图避免使用yum:
[asemani@rcdc9pfda5r Python-3.6.1]$ sudo yum -y install python-pip
[sudo] password for asemeani:
Loaded plugins: security
Setting up Install Process
No package python-pip available.
Error: Nothing to do
另一个编辑:
导入sys后再调用sys.path这是我得到的:
