问题
I am trying to install python-shapely with pip in Ubuntu 10.04. I got "Unknown or unsupported command 'install'" while I tried,
user@desktop:~$ pip install Shapely
I tried installing pip and got the following error:
user@desktop:~$ sudo apt-get install python-pip
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following NEW packages will be installed:
python-pip

Unpacking python-pip (from .../python-pip_0.3.1-1ubuntu2.1_all.deb) ...
dpkg: error processing /var/cache/apt/archives/python-pip_0.3.1-1ubuntu2.1_all.deb (--unpack):
trying to overwrite '/usr/bin/pip', which is also in package pip 0:0.13-1
Errors were encountered while processing:
/var/cache/apt/archives/python-pip_0.3.1-1ubuntu2.1_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
I'd appreciate any comment/solution.
Thanks!

Did you install pip first, then get this error, then try to install python-pip?
If so, first remove pip (apt-get remove pip), then install python-pip instead and try again.
(I just had the same problem, not sure if python 2.7 uses pip and 2.6 uses python-pip? That might be the issue.)

Same happen to me, I'm running Ubuntu Lucid Lynx, 10.04 and there's a packaging conflict. Package pip (pearl installation software) has a conflict with the python-pip package. Both of them try to put a pip binary at /usr/bin/pip. You could do several things to solve the problem so choose the one that fits your needs:
1.- Remove "the pearl pip" if you don't use it and install the python pip
2.- Force installation of python pip with some "dpkg -f" or so, but this way your pip binary file will be overwritten
3.- Manually install ether of the packages changing the binary name, i.e. you manually install the python pip and instead of pip you just call the binary "python-pip"

Seems to be broken download. Did you try easy_install?
sudo easy_install pip
回答4:
The problem raise because pip is in strawberry perl and Python both, if Perl's pip hit this error comes
$ which pip /cygdrive/c/strawberry/perl/bin/pip
Solution 1. C:\Python27\Scripts\pip install south or 2. Keep python path before strawberry perl or 3. remove strawberry perl path from path variable...
回答5:
Leave everything, Install latest version of python from its https://www.python.org/downloads .It already contain PIP, so open CMD from start and give him path to reach folder where python is installed and open "Script" folder where pip is build-in installed e.g. c:\Python36-32\Script And then write pip install module_name and enjoy,,,
Possibly you will have to open Administrator CMD, SO after typing cmd in start when you see CMD is on list press CTRL+SHIFT+ENTER and press OK in pop-up dialog and you will have administrative CMD.
