Can't load Python modules installed via pip from site-packages directory

I am trying to install and use the Evernote module (https://github.com/evernote/evernote-sdk-python) . I ran pip install evernote and it says that the installation worked.

I can confirm that the evernote module exists in /usr/local/lib/python2.7/site-packages. However, when I try to run python -c "import evernote" I get the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named evernote

This is the contents of my .bash-profile:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

# Setting PATH for Python 3.3
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.3/bin:${PATH}"
export PATH
export PATH=$PATH:/usr/local/bin/

I am having this same problem with other modules installed with pip. Help?

EDIT: I am a super newbie and have not edited that .bash-profile file.

EDIT: python -c 'import sys; print "\n".join(sys.path)' Outputs the following:

/Library/Python/2.7/site-packages/setuptools-1.3.2-py2.7.egg
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC
/Library/Python/2.7/site-packages

EDIT: I seemed to have made progress towards a solution by adding export PYTHONPATH=“/usr/local/lib/python2.7/site-packages” to my .bash_profile file. However, now when I run python -c 'from evernote.api.client import EvernoteClient' it tries to import oauth2, which fails with the same error. The ouath2 module is present in the module directory.

People also ask

Why can't I import Python modules?

This is caused by the fact that the version of Python you're running your script with is not configured to search for modules where you've installed them. This happens when you use the wrong installation of pip to install packages.

How do I fix pip module not found?

The Python "ModuleNotFoundError: No module named 'pip'" occurs when pip is not installed in our Python environment. To solve the error, install the module by running the python -m ensurepip --upgrade command on Linux or MacOS or py -m ensurepip --upgrade on Windows.

Why is pip install not working?

This error usually means there's a problem with the Python installation or the system variable PATH is not set up correctly. Try reinstalling Python and all its components to fix the problem. The easiest way is via the Python executable installer.

Where are Python site-packages?

there is a site package directory in a virtualenv. You can get the directory for site-specific modules inside/outside virtualenv using python -c "from distutils. sysconfig import get_python_lib; print(get_python_lib())" (it works on both Python 2 and 3 too). This should be in any basic tutorial on using python.

/usr/bin/python is the executable for the python that comes with OS X. /usr/local/lib is a location for user-installed programs only, possibly from Python.org or Homebrew. So you're mixing different Python installs, and changing the python path is only a partial workaround for different packages being installed for different installations.

In order to make sure you use the pip associated with a particular python, you can run python -m pip install <pkg>, or go look at what the pip on your path is, or is symlinked to.

I figured it out! I added this line:

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/site-packages

to my .bash_profile and now I can import modules stored in that directory. Thanks for everyone who answered.
