I have read a lot of posts about this error, and the reason I am posting this is because I get the error when trying to install statsmodels package, and not one of my programs.
how do I correct the error when installing a package?
$ sudo pip3 install statsmodels

----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_root/statsmodels
Reading the suggested response, I ran:
sudo pip3 install numpy --upgrade
Requirement already up-to-date: numpy in /usr/local/lib/python3.2/dist-packages
Cleaning up...
Uninstalled matplotlib and numpy and then upon installing it again, I get the following message:
sudo pip3 install matplotlib
Requirement already satisfied (use --upgrade to upgrade): matplotlib in /usr/local/lib/python3.2/dist-packages
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.5 in /usr/lib/python3/dist-packages (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): python-dateutil in /usr/local/lib/python3.2/dist-packages/python_dateutil-2.2-py3.2.egg (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): tornado in /usr/local/lib/python3.2/dist-packages (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): pyparsing>=1.5.6 in /usr/local/lib/python3.2/dist-packages/pyparsing-2.0.2-py3.2.egg (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): nose in /usr/local/lib/python3.2/dist-packages (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): six in /usr/local/lib/python3.2/dist-packages/six-1.7.2-py3.2.egg (from python-dateutil->matplotlib)
Cleaning up...
For numpy, the reinstall returns the following:
sudo pip3 install numpy
Requirement already satisfied (use --upgrade to upgrade): numpy in /usr/lib/python3/dist-packages
Cleaning up..
