Python pip – How to get around Fatal error in launcher: Unable to create process using ‘”‘

On some Windows machines pip has a problem caused by spaces in the Python installation path.
When you try:

Note: replace tweepy with the Python package you are trying to install. You will not receive the same output as in this example tweepy is already install via pip!

pip install tweepy

or any other package you get the following error returned:

Fatal error in launcher: Unable to create process using ‘”‘

The first thing you want to do is make sure you update pip:

python -m pip install -U pip

Now if you run:

python -m pip install tweepy

Your package should install.

If that fails, type python into your Windows command prompt to bring up the python command prompt. When you have the python command prompt displaying >>> type:

>>> import pip

Then when the python prompt returns >>> type:

>>>pip.main([‘install’,’tweepy’])

This should workaround the issue an give you back the power of Python pip
