如何通过简易安装安装特定版本的pip？ -Mac OS小牛

Question

I am constantly getting the

Cannot fetch index base URL https://pypi.python.org/simple/

whenever I try to pip install anything with the most recent pip version.

I read on some other questions that pip was having SSL related issues in its latest version and recommended to install pip 1.2.1.

How do I install a specific version of pip via easy_install for example?

Answer 1

您应该可以使用pip安装pip：

pip install --upgrade pip==1.2.1

Answer 2

Based on your context, you can uninstall as above and then run:

sudo easy_install pip==1.2.1

No more pesky SSL errors.

Answer 3

Uninstall any previous installation of pip . Considering you are using system wide installation,

sudo apt-get remove python-pip

and also,

pip uninstall pip

Now,

sudo apt-get install python-setuptools
sudo easy_install pip==<specific version>
sudo pip install virtualenv

It's preferred to use virtual environment though.
