Installing pip using easy_install

问题:

I don't have root access and i want to install python from scratch. So I downloaded the python source code and compiled it. Next I wanted to install pip. But when I ran python get-pip.py I got this error:

ImportError: cannot import name HTTPSHandler

Not having root access then I couldn't install stuff needed. So I thought maybe I can install pip with easy_install so I went and installed setuptools which has easy_install. But when I run easy_install pip I get this error:

Searching for pip

Download error on https://pypi.python.org/simple/: unknown url type: https -- Some packages may not be found!
No local packages or download links found for pip

So now how to install pip? I'm really going crazy!

Edit: I can't use virutalenv

回答1:

try this to install pip : "easy_install-2.7 -U --user pip"

**another important info** 

To install pip on Ubuntu, Debian or Linux Mint:

$ sudo apt-get install python-pip

To install pip on Fedora:

$ sudo yum install python-pip

To install pip on CentOS, first enable EPEL repository, and then run:

$ sudo yum install python-pip

To install pip on Archlinux:

$ sudo pacman -S python-pip

This isn't precisely answering original question but if you're unfortunate enough to be trying to install pip with easy_install on centos6, I hope this helps.

This used to work but now fails with below error:

$ docker run -ti centos:6 bash -c 'yum install -y python-setuptools && easy_install pip'
...
Installed:
  python-setuptools.noarch 0:0.6.10-3.el6                                                                                                                       

Complete!

I guess http://pypi.python.org got serious about requiring https. If you make this little hack then easy_install pip works. sed --in-place 's#http://pypi.python.org#https://pypi.python.org#g' /usr/lib/python2.6/site-packages/setuptools/command/easy_install.py

For those who have no root access, here is how I solved the issue.

1. Download Python (Gzipped source tarball).

2. Unzip and cd to the Python source directory.

3. Configure with the "--with-ensurepip=install" flag, e.g.,

   ./configure --prefix=[your-specified-dir] --with-zlib-dir=/usr/lib64 --with-ensurepip=install
   

4. make & make install

5. Now you should have a working but out-dated pip. To get the latest pip, download the get-pip.py file and run python get-pip.py

Now you should have the latest pip. Enjoy. :)

Virtualenv to the rescue! It comes with pip, doesn't require root access, and allows you to have different environments each with their own copy of python, pip, and modules. The installation docs list several installation methods, you want the last one called "Use locally from source". Please also have a look at virtualenvwrapper, which is just a set of shell scripts that makes working with virtualenv easier. Google will produce ample tutorials on both of these.
