How do I list my pip-installed packages inside a venv?

Question

I have successfully activated a virtual environment and installed packages there, but when I try to list those packages with pip list I get the list of global packages, not those in the activated venv.

$ source ./venv/bin/activate
[venv] pip list
# ... global 2.7 packages are listed
[venv] pip3 list
# ... global 3 packages are listed

but

$ cd venv/lib/pythonXX/site-packages
$ ls
# ...venv's installed packages are listed

even though python -version correctly lists the venv's Python (and not any global version).

How do I list my pip-installed packages inside a venv?

Solution

I resolved this problem by creating a new venv for my project and switch to it. Then, when I activate the venv and "pip list" into it, I list only venv packages. I think this problem happens when you rename project folder or venv folder or move those files maybe to reorganise your project structure.
