py2exe ImportError: No module named cssselect - py2exe

Question

I used pyquery in my App, when I run main.exe in the dist directory, the error occures:
Traceback (most recent call last):
File "main.py", line 4, in <module>
File "zipextimporter.pyo", line 82, in load_module
File "f2.pyo", line 4, in <module>
File "zipextimporter.pyo", line 82, in load_module
File "pyquery\__init__.pyo", line 11, in <module>
File "zipextimporter.pyo", line 82, in load_module
File "pyquery\pyquery.pyo", line 6, in <module>
File "zipextimporter.pyo", line 82, in load_module
File "pyquery\cssselectpatch.pyo", line 6, in <module>
ImportError: No module named cssselect
But as you can see, pyquery uses cssselectpatch not cssselect, how to fix it?

Answer 1

Make sure you can run your program without py2exe, i.e. as a Python script with python main.py.
Use py2exe.
If you still get an error add import cssselect to main.py and try to use py2exe again.

I have the same problem with cssselect, but before that
it was with html5lib, what I did to solve the problem was to install
html5lib manually ex: python setup.py install and a directory was created
and the error regarding html5lib didn't show, then came the error with cssselect,
I did the same thing but the installer creates a egg file not a directory
with all the structure inside, because py2exe only imports the libs with the
directory structure the binary doesn't work.
To solve the problem we have to install cssselect in the tree structure:
download cssselect from github, decompress and copy the dir cssselect that's inside cssselect-master
to your python site-packages.

On Windows (similarity can apply to Linux) you can just install it and the installer will find your local installed python to add cssselect module in. the source info taken from https://pypi.python.org/pypi/cssselect.
Here is how:
pip install cssselect
Now your python will NOT complain for csselect module missing.
If you do not have pip command then install pip.
Tested, Works!
