I successfully install different modules using pip and they are shown in the
pip list
such as:
beautifulsoup4 (4.4.1) requests (2.10.0) Scrapy (1.1.0)
However, whenever I try to import it
import beautifulsoup4
/ import bs4
or import Scrapy
or import requests
the following error is shown:
$ python Python 2.7.5 (default, Mar 9 2014, 22:15:05) [GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import requests Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named requests
Update: if I launch python when I am at the correct site-packages directory
$ pwd /usr/local/lib/python2.7/site-packages $ python Python 2.7.5 (default, Mar 9 2014, 22:15:05) >>> import requests >>> import bs4 >>> import scrapy
Then it works. This would solve the issue if writing directly on the Terminal. However, I have no clue about how to make it work inside a file.py, which will be the normal use.
As far as I know, I only have Python2.7 installed.
If I have a file.py saved in some local folder. This contains, for instance
import requests from bs4 import BeautifulSoup
when I try
python file.py
I get the same error.
Same happens with any other module from the list. I would think pip is installing them in a directory that Python is not reading, but as per what I read, it is the correct one.
They are all installed here:
/usr/local/lib/python2.7/site-packages
Output requested by Padraic Cunningham:
$ which -a pip /usr/local/bin/pip $ which -a python /usr/bin/python /usr/local/bin/python
Output requested by leovp:
$ pip -V pip 8.1.2 from /usr/local/lib/python2.7/site-packages (python 2.7)
I have checked the following threads, but unfortunately they did not help me to solve the issue:
Any ideas of what the problem is?
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.
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.
pip when used with virtualenv will generally install packages in the path <virtualenv_name>/lib/<python_ver>/site-packages .
The Python pip utility is used to install a module, but the import command is used to actually import the module. Python includes some built-in standard modules. These modules are part of the Python Standard Library, also known as the Library Reference.
Here the answer that worked, which is basically what has been explained in the comments of the question. However, I thought it would be useful to have it explained as a clear and well structured answer.
As highlighted, the problem was that I was not using the interpreter that pip was installing for. The command which
shows where pip was installing the modules:
$ which -a pip /usr/local/bin/pip
and where the different python versions were located:
$ which -a python /usr/bin/python /usr/local/bin/python
That is, my system/default python was
/usr/bin/python
while pip was installing for
/usr/local/bin/python
Therefore, I could not import anything I installed when I just typed python
, because the /usr/bin/python
interpreter was the one started.
Install pip again specifying the destination of the modules that will be installed. This must be the destination for the system/default python.
This has been done in two steps:
Downloding get-pip.py
from bootstrap.pypa.io/get-pip.py. (You may need to use the deprecated one for Python 2: bootstrap.pypa.io/2.7/get-pip.py)
Installing it with the following command
sudo /usr/bin/python get-pip.py
Note that without the sudo
I got an error and was not able to install pip.
I have just fixed a similar issue.
To give some background, I install pip
with homebrew
by executing brew install python
. One drawback by executing this command, it will install both python2 and python3(maybe not a disadvantage in some case), then
pip install scrapy
but when I try to import scrapy
, it complained ImportError: No module named scrapy
.
My Solution: run brew doctor
, it should report you a link is broken, it asks you to run brew link python
, you might encounter some errors, but follow the prompt suggestion to move forward, after successfully executing brew link python
, everything should work now.
