I am working in Ubuntu 14.04 and I have multiple versions of Python on my machine (they include python2.7 and python3.4). Few days back, I installed simplejson on my system. I don't remember how I did that but I guess it must be similar to pip install simplejson. However, now a strange problem has started appearing when I try installing any python package. For example, just now I tried installing Tkinter using sudo pip3.4 install Tkinter and it throws the following error:
Traceback (most recent call last):

ImportError: No module named 'json'
Sometimes I can fix this if the error tells me that in one of the files I have:
import json
which I simply convert to
import simplejson as json
I tried uninstalling simplejson:
sudo pip uninstall simplejson
but it gives me the same error: json not found.
Can anybody please help me fix this so that I would happily be able to install python packages? Thanks in advance.
Note: I do not have a definitive answer but will offer a series of steps you can try:
The first thing is see if you can import json from the usual python interpreter:
import json
print(json.__file__) #this would be important to know if it works
If that does work (as well as commenting what json.__file__ is) you would then want to try to use pip from the interpreter.
If you can't import json normally:
This is not surprising, I did not expect pip to be looking in a non-standard place for modules. You will want to figure out where the json package should be located on your computer, you can do this by importing another module from the standard library and looking at it's __file__:
>>> import fractions
>>> fractions.__file__
'/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/fractions.py'
This will obviously be different for you but I'd expect there to be a json folder in the same folder as fractions.py
if you can't import fractions or queue or datetime etc.
If you can't import anything from the standard library you will probably want to just reinstall python.
If the json folder is there and contains an __init__.py
Use the rename function of your file browser to make sure there are no weird special characters, but other then that I'm not sure, if you can import fractions.py but not a package from the same folder that would imply there is something very wrong with the import mechanics of your python version.
If the json folder is not with the rest of the standard library
It is possible that your python distribution has a different structure then I'd expect, it at least can't hurt to take a look for it.
You can search for the json folder amongst your various python files using the find command, not really sure how it works but just another thing to try. If you do find it with the __init__.py, encode.py, decode.py, scanner.py, and tool.py (at least those are the ones in my version) you'll probably want to figure out how it got there, but maybe just move it to the same folder as the rest of the standard library.
If you can't find the json package or you find it and it is corrupted
Well then you will need to replace it! Don't worry, this isn't too hard, just grab a source release of python from the site and extract the json package from it, once it is uncompressed the json folder should be in the Lib folder. Simply copy/move it to the rest of the standard library and you should be good to go!
I hope this helps you debug what is going on, This covers all the scenarios I could imagine happening and I would be interested in which one fixed your issue (or what you were able to figure out so I can come up with more options)
I am guessing that you install it using either pip install simplejson to download from PyPI or using apt-get install python-simplejson to download from ubuntu repositories.
It is possible that you downlaoded the library for the Python2 if you used any of the commands above and it won't be available for Python3 (which pip3.4 will use). Can you try these commands and help debug yourself?
$ python -c "import simplejson"
$ python3.4 -c "import simplejson"
This would tell you which version of the python did you install simplejson for last time (my guess in python2). If the 2nd command errors out with ImportError try:
$ pip3.4 install simplejson
and then install your libraries.

I am attempting to install ckan on my system and I'm following the install from package directions (http://docs.ckan.org/en/latest/maintaining/installing/install-from-package.html). All the dependencies were installed correctly and the ckan package itself downloaded without error. When I went to run the install I got a module missing error for what to me looks like a trivial python module that should be there.

I've confirmed that datetime is installed with a quick python -c 'import datetime' run. At this point I have done a little bit of digging and haven't been able to find anywhere else where this is duplicated nor exactly how to resolve this. Any help or advice is greatly appreciated.
Looking around for the error from plistlib it looks like the same error affecting https://bugs.launchpad.net/ubuntu/+source/python2.7/+bug/1368144
Unfortunately I'm not sure how this would have come about. I'll continue digging and see if I can find out more, but it isn't anything I've seen before but it definitely appears virtualenv related.
I would like to know if there's a way that I can put Scrapy into a subdirectory and import it. I did this with BeautifulSoup, rather than installing it, I just drop the bs4 directory into the directory of my app, and import it:
from bs4 import BeautifulSoup
In the source that I downloaded from scrapy.org there is no scrapy.py so I tried importing
from scrapy import *
This returned a bunch of errors.
Traceback (most recent call last):
File "C:\Users\Kat\Desktop\linkscrape\cookie.py", line 1, in <module> from scrapy import *

from six.moves import copyreg
ImportError: No module named six.moves
Is there any way that I can simply include this to make it easy to migrate the app from computer to computer, or does this have to be installed? Thanks.
Don't do that. You will hurt yourself.
To achieve easy portability, use virtualenv - it's a golden standard of Python development.
Create a file named requirements.txt in a root directory of your project, and write all necessary dependencies, like this:
python-dateutil==2.4.2
Scrapy==1.0.4
XlsxWriter==0.7.7
When you are setting up the environment, create a fresh virtualenv and then simply:
pip install -r requirements.txt
Voilà! You have a working environment.
In case of Scrapy, it's even more important because in production Scrapy is typically deployed using scrapyd, where having a correct package with a version number and fixed requirements is absolutely necessary.
I am trying to import the spherical harmonic toolbox (SHTOOLS) in python. I have the files downloaded and unzipped and am using RedHat.
I added the package's path to my python system path and when I go to import the package, I get this error:
>>import pyshtools
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pyshtools/__init__.py", line 49, in <module>
load_documentation()
File "pyshtools/__init__.py", line 27, in load_documentation
from . import _SHTOOLS
ImportError: cannot import name _SHTOOLS
I can not seem to figure out what the issue is. I checked that the path to this folder was actually added to the system path and it was.
Is this an issue on my end? Or is it possible that I have something downloaded incorrectly? If so, how would I go about fixing this issue?
The SHTOOLS package needs to be built with make first to compile the Fortran libraries. The wiki on Github gives directions on which libraries are required - libblas-dev, liblapack-dev, g++, gfortran, and libfftw3-dev (these are the Ubuntu packages, they may have slightly different names on Redhat). Once these are installed, you need to run make, then sudo make all to install the Fortran and Python components. The Makefile has a lot of good comments in it, I'd recommend reading through it before running make.
My script was running well before. I had a series of crashes on some scripts where I had to fix some things. However, all of a sudden, I can't even run a script and my sublime text shell is displaying this error. I tried chasing down the files in my /Library/...python... files to see if any files got renamed or any part of the module scripts got renamed or something, but have yet to figure it out. What can I try. Or better question, what did I do all of a sudden to cause this, and how would I undo it? It was literally working fine less than an hour ago not to mention all day.

EDIT:
Thanks to the comments! I had tried re-installing pandas, numpy, and Quandl. But it was all due to the fact I had renamed a helper script numbers.py, when it needed to draw that from within. Hint to all future users: Do not rename python scripts to existing module types.
I've had a similar error that was caused by installing a package while I had IPython running. Try reinstalling Pandas using pip (make sure all Python instances are closed) and maybe you'll have to reiinstall hashtable as well, I can't remember.
try to reinstall this Quandl library
File
"/Users/peter/Documents/Trading/Code/AlphaModelVer1/numbers.py", line

pip uninstall Quandl
pip install Quandl
This problem occurred with me in spite of not naming the script name to the existing module name. I tried the following and it worked.
Instead of "import Quandl", I did "from Quandl import Quandl" and it worked for me!
I searched a lot and did not find any answer to this problem =(

I do not understand python and have no idea how to fix this issue, I'm trying to install OSQA to run a phpBB support forum for another country.
Thanks for any help, best regard's.
My guess having had a similar issue on CentOS before, is that the ld path for the new Python isn't set, and it can't find its loadable modules folder.
The 3rd code block on this blog post shows setting an ld path for an opt Python (though it is 2.7): http://toey.tc20.net/2010/08/04/install-python-2-7-gevent-on-centos-5-x86_64/
I would assume that an installer would have done this as part of the install step, but maybe the blog post above will be of some help.
I had the same problem and found that the issue is unrelated to _md5.so, but instead that hashlib is failing to import _hashlib.so within a try block, then getting to a different and normally unused section of code (where the _md5 problem shows up). Try:
import _hashlib.so
I got something like:
ImportError: <PATH>/lib/python2.7/lib-dynload/_hashlib.so: cannot restore segment prot after reloc: Permission denied
I googled that and found http://www.quantumwise.com/forum/index.php?topic=16.0 which says you need to do:
chcon -t texrel_shlib_t <PATH>/lib/python2.7/lib-dynload/_hashlib.so
This worked for me.
Activepython 2.6 seems to have some problem in their latest build. please check for its former release.
I also encounter the same issue like you, I fix it after I add the lib path of python where the module will be installed.
It is really caused by LD_LIBRARY_PATH, please try to add "/opt/ActivePython-2.6/lib" into your LD_LIBRARY_PATH.
setenv LD_LIBRARY_PATH /opt/ActivePython-2.6/lib:$LD_LIBRARY_PATH

I met the similar problem on Redhat 6.4, python binary (2.7.x) packages is copied from other already installed system (which is built from source).
The problem is the _hashlib.so, which miss the libssl.so.0.9.8
bash-4.1# ldd /proj/application/tools/python2.7/lib/python2.7/lib-dynload/_hashlib.so
linux-vdso.so.1 => (0x00007fff51d6f000)
libssl.so.0.9.8 => not found
libcrypto.so.0.9.8 => /usr/lib64/libcrypto.so.0.9.8 (0x00007f9a69746000)
libpython2.7.so.1.0 => /proj/application/tools/python2.7/lib/libpython2.7.so.1.0 (0x00007f9a6936b000)
I just install missed package and soft link to the library.
bash-4.1# yum install -y tar openssh-clients
bash-4.1# ln -s /usr/lib64/libssl.so.0.9.8e /usr/lib64/libssl.so.0.9.8
Then the setuptool installation is successful
