Hi, I've found out that the rosinstall in my robot is not working, basically it says the following:

$ rosinstall
ERROR Cannot find rosinstall libraries, check your installation. One frequent cause is that rosinstall 0.5 is still installed in /usr/local/lib. Check the rosinstall wiki for solutions.
cannot import name get_vcs_client

I don't have any rosinstall library in /usr/local/lib
I've reinstalled rosinstall
I've done #easy_install vcstools (with no change since they were already there)
Computer data
- OS: Ubuntu Server 12.04
- ROS: Fuerte 1.8.10

I've been googleing and the only page I've found with the same problem is this one. But It couldn't help.

Any ideas?

Thanks in advance!

Hi, I had the same problem. first, I updated the packages using $ sudo apt-get update

then, I installed python-vcstools by $ sudo apt-get install python-vcstools

I don't know what happened with 'python-vcstools', but the rosinstall works well now. Hope it will work for you too! :)

Have a nice day!

Thank you, this worked! (I uninstalled everything first)

This also happens when python-vcstools is at an older version than python-rosinstall. Just updating both should solve this. The error message will be changed soon.

Do not mix apt-get installs with easy_install/pip stuff. Please remove all vcstools from /usr/local/lib/..., because it interferes with the apt-get install of python-vcstools.

apt-get installs rosinstall and vcstools to /usr/share/... easy_install/pip install them to /usr/local

If you install both, the binary from /usr/share will attempt to load the libraries from /usr/local, so all kinds of problems occur.

Adding a little more concrete workaround steps I had to take in addition to @KruseT's answer.

Ubuntu Quantal 64b, Groovy

sudo rm /usr/local/lib/python2.7/dist-packages/rosinstall-0.6.17-py2.7.egg/rosinstall -fR
sudo rm /usr/local/lib/python2.7/dist-packages/rosinstall-0.6.17-py2.7.egg/EGG-INFO/scripts/rosinstall 
sudo rm /usr/local/lib/python2.7/dist-packages/vcstools-0.1.18-py2.7.egg/ -fR

I never used easyinstall/pip on this machine at my office so they might have been installed by adminitrators.
