pip not working

Question

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
0 upgraded, 1 newly installed, 0 to remove and 396 not upgraded.

After this operation, 270kB of additional disk space will be used.

Unpacking python-pip (from .../python-pip_0.3.1-1ubuntu2.1_all.deb) ...

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!

Answer 1

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.)

Answer 2

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"
