MySQL-Python (MySQLdb) is known to work with PyPy. How do you make it work?
I tried downloading it and installing:
C:\dev\Installs\MySQL-python\MySQL-python-1.2.3>pypy setup.py install
Traceback (most recent call last):
File "app_main.py", line 51, in run_toplevel
File "setup.py", line 15, in <module>
metadata, options = get_config()
File "C:\dev\Installs\MySQL-python\MySQL-python-1.2.3\setup_windows.py", line 7, in get_config
serverKey = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, options['registry_key'])
WindowsError: [Error 2] The system cannot find the file specified.
Then I tried to download the ctypes implementation which seemed to have installed ok, however trying to use it gave:
...
File "C:\pypy-1.7\site-packages\django\db\backends\mysql\base.py", line 14, in <module>
raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e)
ImproperlyConfigured: Error loading MySQLdb module: Can't find a libmysqlclient
I'm at a loss at this point. How do I make it work
Regarding your second error with mysql-ctypes, the answer is that the line
ctypes.util.find_library('mysqlclient')
can't find the library on windows. Changing it to:
ctypes.util.find_library('mysqlclient.lib')
works on my system - but that only gets you to the next error (windows error 193) on my system.
you're right, the original MySQLdb is known to not work on PyPy.
I never tried to install mysql-ctypes on a windows maschine as I do not have one, but do you have libmysqlclient installed in your PATH?
If so, you may try my (sadly not yet merged) fork on https://github.com/EnTeQuAk/mysql-ctypes which has support for a bit more versions of libmysqlclient.
I had no issues with the MySQLdb package in pypy after installing it using pip.
You can find instructions for installing pip for pypy in the second section of the following link: http://doc.pypy.org/en/latest/getting-started.html#installing-pypy
Once you have pip installed, it's just a matter of running
pip install MySQL-python

I'm trying to follow/modify these instructions to get matplotlib compiled on pypy3, but when I try to compile wxpython-cffi with pypy3 build.py dox I get this error:
Traceback (most recent call last):

File "build.py", line 422, in __init__
os.chdir(newDir)
FileNotFoundError: [Errno 2] No such file or directory: '/Users/user/tmp/docs/doxygen'
The steps I followed are:
installing pypy3 with brew: brew install pypy3
trying to install matplotlib with pip_pypy3 but getting this long error message
trying to install wxpython with pip_pypy3 install wxpython and getting another very long error message
Download wxpython-cffi: hg clone https://bitbucket.org/amauryfa/wxpython-cffi
installing wxWidgets with brew: brew install wxWidgets
which doxygen --> /usr/local/bin/doxygen
export DOXYGEN=/usr/local/bin/doxygen
and finally pypy3 build.py dox which results the error above
changing the line 657 of build.py from pwd = pushDir(posixjoin(wxDir(), 'docs/doxygen')) to pwd = pushDir('/usr/local/bin') results in a completely different error:
Running command: dox
./regen.sh xml
/bin/sh: ./regen.sh: No such file or directory
Command './regen.sh xml' failed with exit code 127.
I would appreciate if you could help me know what is the problem and how I can solve it. the final goal is to get the matplotlib installed on pypy3, so out of the box solutions also would do.
P.S. I'm not sure if my tags are appropriate. I would appreciate if the moderators could let me know if they need to be modified/removed
Matplotlib and PyPy is a known pain point on OSX, we have had multiple reporters but since the PyPy team does not have an OSX developer we cannot fix it on our own. See https://bitbucket.org/pypy/pypy/issues/2327 or any of the other matplotlib issues on the PyPy issue tracker.
It would be great if someone capable of working through this with us would step up and help us fix it, reach out with a response to any of the multiple issues or on IRC at #pypy
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\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 used to install python (2.7.6) packages using sudo pip install [...] until I recently decided that this was a bad idea and I should use: pip install --user [...] instead.
Since I am using Mac OS X (10.10.3), my python modules had been installed into /Library/Python/2.7/site-packages. Now, with the --user option enabled, they are being installed into: /Users/USER/Library/Python/2.7/lib/python/site-packages
I have since moved all packages (including pip/setuptools) into this destination, adjusted my $PYTHONPATH and changed the file ownership to my local user. I expected that I would now be able to call pip install --user [..] and everything should go smoothly.
Unfortunately, this is not the case. For any pip install (or pip install --upgrade) command I receive the same error (below). The same is true when using a virtualenv - the same error shows up and I have no clue why.
However, everything does work "fine", when I use sudo pip install --user, which is why I assume that it is somehow related to a file-permission error I can not see. (It's not exactly fine, as the newly installed package will be in the right location, but all files are owned by root.)
Any idea what I am doing wrong or how to debug this?

I also checked the location of pkg_resources and deleted pkg_resources.pyc, which is located in /usr/local/lib/python2.7/site-packages for some reason, but it didn't change anything. (My local user also has full access rights in this location.)
[UPDATE:]
For some reason I was able to install virtualenv without root (pip install --user virtualenv), but all other packages I tried still fail. Also, if I switch to a new virtual environment, I still receive the same error. I am now thinking this is related to my $PYTHONPATH variable, which appears to not be updated for my virtualenv, but I haven't found the real solution, yet.
Alright, so I found the actual problem and solution. My $PYTHONPATH contained an invalid directory. I setup my $PYTHONPATH a long time ago and wrote it into a .bashrc (or more accurately .bash_profile) script.
pip was probably looking through all directories in $PYTHONPATH, although I don't know what it is doing in each of them that causes the above error, but removing the invalid directory fixed my problems.
I also now highly recommend to just use virtualenv instead of a static setup.
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.
I'm a total python newbie. I installed python 3.3.1 on a 32 bit windows 7 professional. I'm trying to install RapidSMS, and it should be as easy as "pip install rapidsms" and it does start the process, but it doesn't complete and I'm left with the below error message.
I've been trying to google it, but I haven't been able to find this specific problem, for the error I find fixes for people who have written the code themselves, and I haven't seen anyone mention this problem about rapidsms themselves. Since it stops in Django-tables, I wonder if I messed up that installation somehow or if there's a problem with the python version compatibility. I've used pip when installing some other software, so I don't think that's the problem.
So if anyone's encountered this error when installing pyhton packages or really have any idea what the cause might be I'd really appreciate it! (I also plan to post this in the RapidSMS mailing list when I get approved, but wanted to see if this was a more general problem that might have a fix.)

Django-tables2 fails to install in Python3 because of the following code from line 7 of setup.py in the traceback:
version = re.search('__version__ = "(.+?)"', f.read()).group(1)
This should work if the search pattern was a bytes object. A byte literal can be created by simply pre-pending the string literal with a b like the following:
version = re.search(b'__version__ = "(.+?)"', f.read()).group(1)
This is why Python is throwing a TypeError with the message "Can't use a string pattern on a bytes-like object". The file contents are being read in as bytes.
I don't think RapidSMS currently supports Python3 yet based on its list of environments that are tested. This can be seen in the tox environments list of the project seen here, in which only Python 2.6 and 2.7 are listed: https://github.com/rapidsms/rapidsms/blob/develop/tox.ini#L2
To solve the immediate problem, you'll want to install RapidSMS in a virtual environment with Python 2.6 or 2.7. The documentation for RapidSMS describes virtual environment setup briefly here: http://www.rapidsms.org/en/develop/topics/virtualenv.html
You'll want to install Python 2.6 or 2.7 on your system and specify which Python for the virtualenv to use, using the -p or --python argument. The following is taken from the RapidSMS docs linked above, but ammended to specify using Python 2.7:
mkvirtualenv --distribute --no-site-packages rapidsms --python=python2.7
