Python Pip Install Module Is Not Found. How to Link Python to Pip Location

Python pip install module is not found. How to link python to pip location?

As a quick workaround, and assuming that you are on a bash-like terminal (Linux/OSX), you can try to export the PYTHONPATH environment variable:

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

For Python 2.7

Unable to import a module that is definitely installed

In my case, it is permission problem. The package was somehow installed with root rw permission only, other user just cannot rw to it!

Why am I getting ImportError: No module named pip ' right after installing pip?

Just be sure that you have include python to windows PATH variable, then run python -m ensurepip

Module not found even if it is in pip

Yes I found myself the solution. Thanks to @user42 for the link. I used this command and it worked.

pip install --upgrade google-api-python-client

I have put the answer because it may help people who are facing or will be facing the same problem.

Python - Module Not Found

All modules in Python have to have a certain directory structure. You can find details here.

Create an empty file called __init__.py under the model directory, such that your directory structure would look something like that:

.
└── project
    └── src
        ├── hello-world.py
        └── model
            ├── __init__.py
            └── order.py

Also in your hello-world.py file change the import statement to the following:

from model.order import SellOrder

That should fix it

P.S.: If you are placing your model directory in some other location (not in the same directory branch), you will have to modify the python path using sys.path.

Module not found error in Python after pip install package --user

You're probably attempting to download package to a system folder where you don't have permission to write or modified, maybe it's due to modification on your pip.ini file which specify by default the packages location ?

Check pip documentation and his topic about configuration here.

Furhtermore, I advise you, if you start learning python and using pip package, to learn fundamental about the principle of virtualenv using venv lib here. VirtualEnv is a recommended practice in python who allow you to compartmentalize project in a specified place with a personal pip package directory and other things, these methods aim to avoid dependancy concurrence between projects and also avoid pip package permissions issue by downloading pip package only for your virutalenv.

• Step by step to setup venv ( you should be in the root folder of your
  projet) :

user@hostname > python3 -m venv venv
user@hostname > source ./env/bin/activate
(venv) user@hostname > python -m pip install foo-packages 

• Or the second option but not recommended is to use sudo to
  install packages to the system folder :

sudo@hostname > sudo python -m pip install foo-packages

pip' is not recognized as an internal or external command

You need to add the path of your pip installation to your PATH system variable. By default, pip is installed to C:\Python34\Scripts\pip (pip now comes bundled with new versions of python), so the path "C:\Python34\Scripts" needs to be added to your PATH variable.

To check if it is already in your PATH variable, type echo %PATH% at the CMD prompt

To add the path of your pip installation to your PATH variable, you can use the Control Panel or the setx command. For example:

setx PATH "%PATH%;C:\Python34\Scripts"

---

Note:
According to the official documentation, "[v]ariables set with setx variables are available in future command windows only, not in the current command window". In particular, you will need to start a new cmd.exe instance after entering the above command in order to utilize the new environment variable.

Thanks to Scott Bartell for pointing this out.
