How to install Python module on Ubuntu

Question

I just wrote a function on Python. Then, I wanted to make it module and install on my Ubuntu 11.04. Here is what I did.

Created setup.py along with function.py file.
Built distribution file using $Python2.7 setup.py sdist
Then installed it $Python2.7 setup.py install

All was going fine. But, later I wanted to use the module importing it on my code. I got import error: ImportError: No module named '-------'

PS. I searched over google and didn't find particular answer. Detailed answer will be much appreciated.

Are you trying to install to global python?. Then you need root permission for "$Python2.7 setup.py install" — Jayesh

But do you have write permission to its lib?. Try "$which python2.7". If that shows /usr/bin/python2.7, you might need root access. — Jayesh

Are you sure the setup.py install command didn't error? You WILL need to call sudo for it to write the compiled modules to the python library directory in Ubuntu. — jyore

"Last line message is this". That's not 'site-packages'. Your code needs to be installed in site-packages. Please include the actual log with the actual commands and actual output in your question. — S.Lott

Most installation requires:

sudo python setup.py install

Otherwise, you won't be able to write to the installation directories.

I'm pretty sure that (unless you were root), you got an error when you did

python2.7 setup.py install

I could not install any modules or eggs until I used the package manager to install (for my version) python2.6-dev

 sudo apt-get install python2.6-dev

After that, I was able to run the setup.py file that was included in the downloaded and unpacked module without gcc errors. I assume python2.6-dev is the "development package".
