lately using 9.0.1, I have been using Project Interpreter to import modules for my files. I opened up a new project in PyCharm today to try and test 10.0.1. Using the Pip version of 10.0.1, I couldn't install packages into my file.
The command output was :
Traceback (most recent call last):
File "C:\Program Files\JetBrains\PyCharm Community Edition 2017.3.3\helpers\packaging_tool.py", line 192, in main
retcode = do_install(pkgs)
File "C:\Program Files\JetBrains\PyCharm Community Edition 2017.3.3\helpers\packaging_tool.py", line 109, in do_install
return pip.main(['install'] + pkgs)
AttributeError: module 'pip' has no attribute 'main'
I googled this and it said that installing modules through pip was now unsupported, especially for
pip._internal.main
After looking at this site : https://pip.pypa.io/en/latest/user_guide/#using-pip-from-your-program for a while, it says to use :
subprocess.check_call([sys.executable, '-m', 'pip', 'install', 'my_package'])
I tried executing it and command prompt said that subprocess.check_call is not an internal or external file.
i also tried executing the commands through Command Prompt and downgrading my pip to 9.0.1 but none of this worked. When I changed Pip to 9.0.1 in Command Prompt, it had no effect on PyCharm.
Can anyone help with trying to import modules into PyCharm because I am currently trying to make a webcrawler using modules beautifulsoup4 and it is not letting me import it.

I use QGIS 3.6 and Python 3.7 and I try to install a package with pip in command line tool under Windows 7 but I have the following message :
Fatal Python error: initfsencoding: unable to load the file system codec
ModuleNotFoundError: No module named 'encodings'
Current thread 0x0000188c (most recent call first):
My path and PYTHONPATH are well configured with link to QGIS' Python folders. The problem appeared recently with use of Python 3.7.
At least for Mac recent QGIS versions seem to support only Python 3.6, not 3.7, see https://qgis.org/en/site/forusers/download.html
So I've installed scons via Anaconda's conda install scons under Windows 10 (Python 3.6) and could not execute it via the command line so I've added C:\Users\D\Anaconda3\envs\py36\Scripts\ to my Path (even tough C:\Users\Dominik\Anaconda3 was already in there).
Now I can execute it in the Powershell, but I get an error, because it is unable find engine files:
scons
SCons import failed. Unable to find engine files in:
C:\Users\D\Anaconda3\envs\py36\Scripts\..\engine

Traceback (most recent call last):
File "C:\Users\D\Anaconda3\envs\py36\Scripts\scons.py", line 192, in <module>
import SCons.Script
ImportError: No module named 'SCons'
Does someone know how to further investigate/fix this problem?
I found it thanks to nekomatic.
If you use the anaconda prompt (with the correct environment activated or in my case the correct shortcut leading to anaconda prompt in that environment), scons runs just fine.
See this link explaining how anaconda uses the path on windows and whats the advantage of using the anaconda prompt (mainly it dynamically manages PATH correctly for that session only with full knowledge of conda environments).
I have some difficulties trying to install Scipy for Python 3.5 on a Windows 10 machine and I hope I can find some help here. So here is what I have done so far.
I have downloaded the numpy+mkl for python 3.5 and 64bit version as well as the scipy0.18.1 for the same versions, from Gohlke's website
I installed the numpy+mkl whl with:
python -m pip install numpy-1.11.2+mkl-cp35-cp35m-win_amd64.whl
all goes well.
then I install the scipy package the same way like:
python -m pip install scipy-0.18.1-cp35-cp35m-win_amd64.whl
This also completes.
However, when I try to run python afterwards I get the following error:
Fatal Python error: Py_Initialize: can't initialize sys standard streams
Traceback (most recent call last):
File "C:\Python35\Lib\site-packages\scipy\io\__init__.py" , line 97, in <module>
File "C:\Python35\Lib\site-packages\scipy\io\matlab\__init__.py", line 13 in <module>
File "C:\Python35\Lib\site-packages\scipy\io\matlab\mio.py", line 8 in <module>
ImportError: No module named 'numpy'
I also get a pop-up that Python has stopped working.
I have tried a different order in which I installed the packages, but all lead to the error mentioned when Scipy is installed.
I also installed did this on a windows 7 machine and there it works.
Does anybody have any idea what causes this issue?
I also had some issues. So I just installed Anaconda3 insted of python directly.
I am a complete newbie at Python. I wanted to try to see if Pyomo (a Python package for mathematical modeling) could work under IronPython because all my code for generating the data needed for Pyomo is in C#.
I installed IronPython 2.7.5, then tried as an administrator the advice found in http://blog.ironpython.net/2014/12/pip-in-ironpython-275.html#disqus_thread on how to run "pip" for IronPython. I used the exact example they gave (installing html5lib):
ipy -X:Frames -m ensure pip
ipy -X:Frames -m pip install html5lib
The first line worked, and I see in the Lib/site-packages directory a folder called pip-6.1.1-py2.7.egg with lots of python code in it.
For the second line, I received the error:
Unhandled exception:
Traceback (most recent call last):
File "C:\Program Files (x86)\IronPython 2.7\Lib\runpy.py", line 170, in run_module
File "C:\Program Files (x86)\IronPython 2.7\Lib\runpy.py", line 111, in _get_module_details
ImportError: No module named urllib; 'pip' is a package and cannot be directly executed
At this point, I'm stuck. Any help would be appreciated.
Just in case this helps, printing out the sys.version gives:
2.7.5 (IronPython 2.7.5 (2.7.5.0) on .NET 4.0.30319.34209 (32-bit))
I encountered the same problem. It seems that IronPython can't deal with more recent versions of pip. What I did was:
remove all traces from pip and setuptools from IronPython's Lib\site-packages folder
run from a commandline: ipy.exe -X:Frames -m ensurepip
this installed an old version of pip, one that IronPython understands. Verify this by checking that a folder pip-1.5.6.dist-info appears in IronPython's Lib/site-packages
Moral of the story; don't upgrade to a newer pip version when using IronPython
Hello I am trying to install python-twitter and one of the dependencies HTTPLIB2 is giving me a lot of problems. I have searched the internet up and down but maybe I do not know what the right key words are. Here is the problem.
I am installing python-twitter. I install the requirements either by "pip install -r requirements.txt" or doing them one by one through for example "pip install httplib2". Then I run "python setup.py install". It's happy but then "python setup.py test" fails as followed with an error on import HTTPLIB2.

But I thought the print error was an incompatibility between python 2 and 3. Why am I getting this while I clearly have python 2.7 (I checked and uninstalled and reinstalled HTTPLIB2).
Thanks much for your help
i had a same issue. It seems to be python2.7 and 3.x version conflict issue and resolved by
python2.7 -m pip install -t lib/ -r requirements.txt
Just in case, this happens when you install httplib2 with a python3 version of pip and then execute it with python2.
This happens for example when creating manually an environment with:
pip install -t lib/ -r requirements
As it happens when creating an AppEngine standard environment vendor folder.
This happens because contrary to most of the libraries, httplib2 has completely different versions for python2 and python3.
