no module found PIL but it is installed and up2date

Question

I am trying to download images with scrapy on mac os X and it returns the following error msg:

ModuleNotFoundError: No module named 'PIL'
$ pip install image
Requirement already satisfied: image in /Library/Python/2.7/site-packages (1.5.27)
Requirement already satisfied: django in /Library/Python/2.7/site-packages (from image) (1.11.16)
Requirement already satisfied: pillow in /Library/Python/2.7/site-packages (from image) (5.3.0)
Requirement already satisfied: pytz in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python (from django->image) (2013.7)

Lets try to install the image package:

$ pip install image
Reqfuirement already satisfied: image in /Library/Python/2.7/site-packages (1.5.27)
Requirement already satisfied: django in /Library/Python/2.7/site-packages (from image) (1.11.16)

Requirement already satisfied: pytz in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python (from django->image) (2013.7)

Update pip?

pip install --upgrade pip
Requirement already up-to-date: pip in /Library/Python/2.7/site-packages/pip-18.1-py2.7.egg (18.1)

Python ist installe via homebrew

PIP via sudo: sudo pip install image

Which version of Python do you want to use? You seem to claim you installed Python via homebrew but you are using Python 2.7 as supplied by Apple in /usr/bin/python and that is why pip is installing in /Library/Python/2.7.

If you want to use homebrew Python and pip you need to be running /usr/local/opt/python/libexec/bin/python. You can see all this information if you run:

brew info python

In general, anything that looks in or is installed in /anywhere/LOCAL/anywhere will be homebrew. Anything that uses /usr/bin or /Library/anywhere will be Apple-supplied.

If you want to know which actual command you are running, use type like this:

type python
python is hashed (/usr/local/opt/python/libexec/bin/python)

So that tells me that, on my machine, python is the one in /usr/local/... which must be from homebrew because it contains /.../LOCAL/...

Your python is currently /usr/bin/python. If you want to use the homebrew one, you need to change your PATH in you login profile and put /usr/local/opt/python/libexec/bin before /usr/bin. E.g.:

export PATH=/usr/local/opt/python/libexec/bin:$PATH

Then start a new Terminal so that you are running with the new profile.

Note the difference:

# Run the old Apple-supplied Python
/usr/bin/python -V
Python 2.7.10

# Run the shiny new homebrew Python
/usr/local/opt/python/libexec/bin/python -V
Python 3.7.1

# Run the homebrew pip - that installs into /something/LOCAL/something - sure sign it is not Apple's
/usr/local/opt/python/libexec/bin/pip show pip

I did the export command and now I get the 3.7.1 version in the same terminal. However if I open a new terminal, I am getting the old version. Within the terminal running 3.7.1 the same problem occures, I posted the output as addtional info to the question. Looks OK to me, but still the same errror. — merlin, Nov 30 '18 at 12:09
You need to edit your login profile, and do the `export` in there too - it is probably `$HOME/.profile` then it will set the PATH every time you log in. When you get `python -V` and `pip -V` telling you the **homebrew** version, you will need to run `pip install pillow` because, at the moment, you have installed Pillow for Apple Python v2.7 — Mark Setchell, Nov 30 '18 at 13:05
