pip损坏，无法重新安装. EC2 [英] pip broken, reinstall doesn't work. EC2

问题描述

我现在在EC2上使用pip，python版本是2.7. "sudo pip"突然不再起作用.

I am using pip on EC2 now, python version is 2.7. 'sudo pip' suddenly doesn't work anymore.

[ec2-user@ip-172-31-17-194 ~]$ sudo pip install validate_email

推荐答案

首先，which pip不会返回与sudo which pip相同的结果，因此您应该先检查一下.

first, which pip is not going to return the same result as sudo which pip, so you should check that out first.

您还可以考虑根本不将pip作为sudo运行. 是否可以接受&可以在sudo下运行pip install吗?

you may also consider not running pip as sudo at all. Is it acceptable & safe to run pip install under sudo?

第二次，您可以尝试一下吗?

second, can you try this:

easy_install --upgrade pip

如果在此遇到错误(关于pip的滚轮支撑)，请尝试此操作，然后再次运行以上命令:

if you get an error here (regarding pip's wheel support), try this, then run the above command again:

easy_install -U setuptools
