Why does pip fail when installing local egg repository?

I am working on Windows 7.I have created a python egg using distutils. Now I try to install this egg in a virtual environment using pip 1.0.2 using the following command:

Then I create a virtual environment myVirtualEnv I activate it using activate.bat then execute the following command:

pip install path_to_my_local_folder#eggName

This creates a copy of my egg in my myVirtualEnv\build directory but I have the following error:

I开发者_如何学运维OError: [Errno 2] No such file or directory: path_of_my_virtualEnv\build\PyEqdR\setup.py

Do you know why pip is looking for the setup.py file. Should I include it in the egg ?

pip doesn’t do everything that easy_install does. Specifically:

It cannot install from eggs. It only installs from source.

I just came across this page and since I had the same exact problem, I thought to post the solution that worked for me.

This is an issue with the older versions of pip. My version of pip was 1.5.4. I was not able to find the first version of pip that was able to do it but the current version 6.0.6 does the job.

To update to latest pip version, simply run the following command:

pip install --upgrade pip

Needless to say if you want this to only take effect inside your virtual environment, run it inside the environment. Otherwise, run it globally.
