无法在mac上安装python3的pip

Question

当我跑步时

curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py
sudo python3 get-pip.py

它给了我这个错误：

Downloading/unpacking pip
  Cannot fetch index base URL https://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement pip
Cleaning up...
No distributions at all found for pip
Storing debug log for failure in /var/root/.pip/pip.log

但是，如果我只是运行：

sudo python get-pip.py

没有问题：

Downloading/unpacking pip from https://pypi.python.org/packages/py2.py3/p/pip/pip-1.5.2-py2.py3-none-any.whl#md5=445a893564065937c0f31ac2cc8e2f35
  Downloading pip-1.5.2-py2.py3-none-any.whl (1.2MB): 1.2MB downloaded
Installing collected packages: pip
  Found existing installation: pip 1.5.1
    Uninstalling pip:

有人可以帮忙吗？谢谢！

这是一个简单的权限问题。如果您要安装到系统Python安装，则应该需要root，这是sudo提供的。

如果您需要安装没有root权限的东西，则需要查看Python virtual environments。
