ImportError: No module named PIL

问题:

I use this command in the shell to install PIL:

easy_install PIL

then I run python and type this: import PIL. But I get this error:

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

I've never had such problem, what do you think?

回答1:

On some installs of PIL, You must do

import Image

instead of import PIL (PIL is in fact not always imported this way). Since import Image works for you, this means that you have in fact installed PIL.

Having a different name for the library and the Python module is unusual, but this is what was chosen for (some versions of) PIL.

You can get more information about how to use this module from the official tutorial.

PS: In fact, on some installs, import PIL does work, which adds to the confusion. This is confirmed by an example from the documentation, as @JanneKarila found out, and also by some more recent versions of the MacPorts PIL package (1.1.7).

回答2:

In shell, run:

pip install Pillow

Attention: PIL is deprecated, and pillow is the successor.

回答3:

On a different note, I can highly recommend the use of Pillow which is backwards compatible with PIL and is better maintained/will work on newer systems.

When that is installed you can do

import PIL 

or

from PIL import Image

etc..

回答4:

At first install Pillow with

pip install Pillow

or as follows

c:\Python35>python -m pip install Pillow

Then in python code you may call

from PIL import Image

"Pillow is a fork of PIL, the Python Imaging Library, which is no longer maintained. However, to maintain backwards compatibility, the old module name is used." From pillow installed, but "no module named pillow" - python2.7 - Windows 7 - python -m install pillow

This worked for me on Ubuntu 16.04:

sudo apt-get install python-imaging

I found this on Wikibooks after searching for about half an hour.

Sometimes I get this type of error running a Unitest in python. The solution is to uninstall and install the same package on your virtual environment.

Using this commands:

pip uninstall PIL

and

pip install  PIL 

If for any reason you get an error, add sudo at the beginning of the command and after hitting enter type your password.

回答7:

On windows, try checking the path to the location of the PIL library. On my system, I noticed the path was

\Python26\Lib\site-packages\pil instead of \Python26\Lib\site-packages\PIL  

after renaming the pil folder to PIL, I was able to load the PIL module.

回答8:

you have to install Image and pillow with your python package.

type

python -m pip install image 

or run command prompt (in windows), then navigate to the scripts folder

cd C:\Python27\Scripts

then run below command

pip install image

回答9:

instead of PIL use Pillow it works

easy_install Pillow

or

pip install Pillow

回答10:

You will need to install Image and pillow with your python package. Rest assured, the command line will take care of everything for you.

Hit

python -m pip install image

回答11:

if you use anaconda:

conda install pillow

回答12:

On Windows, you need to download it and install the .exe

https://pypi.python.org/pypi/Pillow/2.7.0

回答13:

I had the same issue while importing PIL and further importing the ImageTk and Image modules. I also tried installing PIL directly through pip. but not success could be achieved. As in between it has been suggested that PIL has been deprectaed, thus, tried to install pillow through pip only. pillow was successfully installed, further, the PIL package was made under the path : python27/Lib/site-packages/.

Now both Image and ImageTk could be imported.

I recently installed Leap. I Tried openshot and it didn't start. So came here and found a suggestion to start from the Terminal to see if there were any error.

The error I had was error missing mlt. So I installed the python-mlt module from Yast and imported it, tried to start but next openshot said missing pil.

I Followed the Pillow suggestion to install because Yast couldn't find any pil and imported pil. That went ok but did not start and showed Error missing goocanvas.

The I installed goocanvas with Yast, imported it in python, and Openshot fired up !!

With a lot of errors in the terminal like missing Vimeoclient and lots of attributeerrors. Well, will see if it is of any influence working with it.

I used conda-forge to install pillow version 5, and that seemed to work for me:

conda install --channel conda-forge pillow=5

the normal conda install pillow did NOT work for me.

回答16:

I had the same problem and i fixed it by checking what version pip (pip3 --version) is, then realizing I'm typing python<uncorrect version> filename.py instead of python<correct version> filename.py

回答17:

You are probably missing the python headers to build pil. If you're using ubuntu or the likes it'll be something like

apt-get install python-dev
