pip3失敗，但點子與virtualenv正常工作

Question

我想爲python3安裝virtualenv。 我一直試圖找出過去一小時，沒有運氣。

root@XXXX:~# pip3 install virtualenv 
Downloading/unpacking virtualenv 
    Cannot fetch index base URL https://pypi.python.org/simple/ 
    Could not find any downloads that satisfy the requirement virtualenv 
Cleaning up... 
No distributions at all found for virtualenv 
Storing debug log for failure in /root/.pip/pip.log 
root@XXXX:~# vim /root/.pip/pip.log 
root@XXXX:~# pip install virtualenv 
Downloading/unpacking virtualenv 
    Downloading virtualenv-13.1.2-py2.py3-none-any.whl (1.7MB): 1.7MB downloaded 
Installing collected packages: virtualenv 
Successfully installed virtualenv 
Cleaning up... 

正如您所看到的，pip工作得很好，但pip3超時。

據失敗輸出pip.log，PIP3超時試圖從PyPI將要求：

/usr/bin/pip3 run on Wed Dec 2 08:45:51 2015

    raise DistributionNotFound('No distributions at all found for %s' % req) 
pip.exceptions.DistributionNotFound: No distributions at all found for virtualenv 

任何提示，我怎麼能解決這個將是巨大的。提前致謝。

沒有virtualenv中的PIP 3，但它很容易建立一個新的環境中使用python3

1. 您與正常PIP安裝

pip install virtualenv

配置新virtualenv使用python3

virtualenv -p python3 envname
