Virtualenv：出錯

Question

$ virtualenv envv 
Traceback (most recent call last): 
    File "/home/rohit/bin/virtualenv", line 5, in <module> 
    from pkg_resources import load_entry_point 
    File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 2880, in <module> 
    parse_requirements(__requires__), Environment() 
    File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 596, in resolve 
    raise DistributionNotFound(req) 
pkg_resources.DistributionNotFound: virtualenv==1.9.1 

通過突觸包重新安裝，但得到同樣的問題。好心幫

Answer 1

我清除了包在錯誤中提到的特定文件夾，並用命令

pip install virtualenv 

這麼簡單

重新安裝
