I am having a problem installing the Python MySQL connector (MySQL-python-1.2.3c1) on my Mac OSX Snow Leopard.
System State
I have manually compiled an installed:
mysql-5.1.41
This seems to work fine, as I can create and query a database from the commandline.
I have compiled:
MySQL-python-1.2.3c1
I first set the following in the site.cfg file:
mysql_config = /usr/local/mysql/bin/mysql_config
I then built and compiled MySQL-python-1.2.3c1 following their guide:
sudo python setup.py build
sudo python setup.py install
I now test the installation with Python:
python -c "import MySQLdb"
Error Message
This then gives me the following error, and I'm stumped as to how to fix it:
Traceback (most recent call last):

Things I've Tried
I've looked at this blog antoniocangiano.com but it is for an older version of MySQL-python and is not really applicable. But I tried adding the soft link it mentions.
I then looked at this blog post: http://blog.some-abstract-type.com/2009/09/mysql-python-and-mac-os-x-106-snow.html. And tried building compiling with the ARCHFLAGS settings - but no joy.
Please Help
If you have any ideas please let me know.
Many thanks
Ben...
First, I would suggest using the MySQL binaries for MacOS X 10.5 64-bit (x86_64). The tar ball works on MacOS X 10.6.
You said you used ARCHFLAGS.. however, try it again like this:
shell> ARCHFLAGS="-arch x86_64" python setup.py build
shell> sudo python setup.py install
Thus building as normal user, installing as root. (It's good to remove the source, and unpack correcting the site.cfg file again).
What does
otool -L /Users/username/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so
report?

I am writing because I am having trouble installing Pyomo using pip on Python 3.6 on Mac OSX 10.14
I'm following the installation instructions here.
I can successfully execute the first command:
pip install pyomo
But when I run into trouble when I'm supposed to run the following command to install additional dependencies:
pyomo install-extras
Running this command produces the following error:
Traceback (most recent call last):
File "/usr/local/bin/pyomo", line 11, in <module>
sys.exit(main())
File "/usr/local/lib/python3.6/site-packages/pyomo/scripting/pyomo_main.py", line 82, in main

th.join()
UnboundLocalError: local variable 'th' referenced before assignment
There is a post about this here on Google Groups but no solution yet.
This is a documented issue on the github for Pyomo: https://github.com/Pyomo/pyomo/issues/243
They don't appear to have solved the pip installation of pyomo extras.
However, if you have conda installed - https://docs.conda.io/en/latest/
You should be able to use the terminal commands from:
https://pyomo.readthedocs.io/en/latest/installation.html
run this in terminal after conda has been successfully installed:
conda install -c conda-forge pyomo.extras
I know this isn't pip, but it's at least a workaround until pyomo fixes their documentation.
confirmed working on python 3.x and ubuntu 18.04
I got the problem too (in Ubuntu 18.04).
Try installing it from the git project (https://github.com/Pyomo/pyomo):
In Ubuntu 18.04:
git clone https://github.com/Pyomo/pyomo.git
python3 pyomo/scripts/get_pyomo_extras.py
Use the corresponding commands for Mac OSX (I had never used it).
I hope that it works for you.
I would like to use cx_freeze to change my hello_world.py into exe file.
When I run cxfreeze like this:
cxfreeze hello_world.py
And I run the exe file, it comes the error:

Fatal Python error: Py_Initialize: Unable to get the locale encoding

zipimport.ZipImportError: can't decompress data; zlib not available

Does anyone know how to solve this?
Run the below code which will install zlib:
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
Thanks to the answer at https://stackoverflow.com/a/52756409/9162193
On MacOS the issue is often that an XCode update has removed zlib. The solution in these cases would be running:
xcode-select --install
On Linux machines you would need to install zlib, see for instance this answer.
I've looked at quite a lot of related questions here - no help for me. I need to repair easy_install, so that I can update distribute to a version >=0.6.28, so that I can update python matplotlib using pip and not yum.
In the process of trying to update python matplotlib from 0.99 (the default with Centos64) to 1.4.x, I got into this trouble:
pip install --upgrade matplotlib tells me this:
Complete output from command python setup.py egg_info:
The required version of distribute (>=0.6.28) is not available,
and can't be installed while this script is running. Please
install a more recent version first, using
'easy_install -U distribute'.
(Currently using distribute 0.6.10 (/usr/lib/python2.6/site-packages))
So I followed the suggestion and saw that some 0.7.x version of distribute was installed (so it seemed). Re-ran the pip command and got the exact same complaint.
Trouble with easy_install?
It was either now, or maybe after performing yum remove, then install python-setuptools that I discovered easy_install is thoroughly broken. Now when I try to run easy_install, I get this stacktrace:
Traceback (most recent call last):
File "/usr/local/bin/easy_install", line 9, in <module>
load_entry_point('distribute', 'console_scripts', 'easy_install')()
File "/usr/local/lib/python3.3/site-packages/setuptools-18.2-py3.3.egg/pkg_resources/__init__.py", line 558, in load_entry_point

File "/usr/local/lib/python3.3/site-packages/setuptools-18.2-py3.3.egg/pkg_resources/__init__.py", line 2681, in load_entry_point
raise ImportError("Entry point %r not found" % ((group, name),))
ImportError: Entry point ('console_scripts', 'easy_install') not found
Look at that - why is it referring to python3.3? I don't think I've got that installed. My default python is 2.6.6.
Any ideas? TIA.
Fixed it. The python3.3 bit was my clue. I found the python script for easy_install, in /usr/local/bin. The very first line designated /usr/bin/python3.3 to execute the script. Changed to 2.6 and then was good to go.
In the end I was not able to upgrade matplotlib from 0.99 to 1.4.3, because I could not upgrade basemap from 0.99 and some conflicts arose. Rather than punish myself with trying to build from source, I think I should simply upgrade my entire VM to Centos7 and I will then have much newer matplotlib.
I have installed Python via Homebrew. I also installed pygtk via Homebrew
I went to install gtimelog via pip but it tells me it's already installed, it appears to have come down with Python in Homebrew
When I attempt to run gtimelog I get ImportError: No module named pygtk
It appears to be a $PYTHONPATH issue but I can't seem to resolve it.
I run into the same issue. Read the Homebrew log:
==> Installing pygtk
==> Downloading http://ftp.acc.umu.se/pub/GNOME/sources/pygtk/2.24/pygtk-2.24.0.tar.bz2
######################################################################## 100.0%
==> ./configure --prefix=/usr/local/Cellar/pygtk/2.24.0
==> make install
==> Caveats
For non-Homebrew Python, you need to amend your PYTHONPATH like so:
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH
==> Summary
The problem is that even with the right PYTHONPATH I'm getting an error when running gtimelog:
$ gtimelog
Traceback (most recent call last):
File "/usr/local/bin/gtimelog", line 8, in <module>
load_entry_point('gtimelog==0.8.0dev', 'gui_scripts', 'gtimelog')()

TypeError: <gtk.Window object at 0x10b443cd0 (GtkWindow at 0x7fe09aacd1d0)>: unknown signal name: style-updated
**Update:
For Mountain Lion you need to install XQuarks as apple doesn't ship X11 with their OS anymore..
As per why gtimelog wasn't opening, It is a gtimelog bug and if you edit ~/.gtimelog/gtimelogrc and set show_tray_icon to False you will get it working!
Easy_install and Pip doesn't work anymore on python 2.7, when I try to do:
sudo easy_install pip
I get:
Traceback (most recent call last):

And when I try:
sudo pip install [package]
I get:
Traceback (most recent call last):

I've already install both of them (and yes, first deleted them), but no result...
Thanks!
(I tried already this post)
I had this issue where python's distribute package wasn't installed for some reason. After following the instructions on python-distribute, i got it working.
install the distribute package as follows:
$ wget https://web.archive.org/web/20100225231201/http://python-distribute.org/distribute_setup.py
$ python distribute_setup.py
EDIT: http://python-distribute.org/distribute_setup.py no longer works:
hopefully this will resolve your problem with running
$ sudo easy_install
Happy Coding!
If you installed a new version of easy_install through Distribute, the new command may have been installed in another directory, most likely /usr/local/bin/. But the traceback shows you were using /usr/bin/easy_install. Try this:
sudo /usr/local/bin/easy_install ...
Try
sudo easy_install Distribute
and if that exists, but is too old
sudo easy_install -U Distribute
Looks like either Distribute/setuptools (it's old name) is messed up or Python package settings. If either of these do not help, try removing the full Python 2.7 installation and reinstall everything from the scratch.
Possible reasons for the mess is that you have used both sudo easy_install / sudo pip and Linux distribution packages to mix and match system-wide installation packages. You should use virtualenv instead if you use pip/easy_install (no sudo needed)
http://pypi.python.org/pypi/virtualenv
I had a similar problem, but things were working fine as root. In my case, I found that the permissions on the python packages were not readable by the ID I was running the command under.
To correct it, I ran the following command to open the permission for read and execute to all users:
sudo chmod o+rx -R /usr/local/lib/python2.7/dist-packages/*.egg
I had similar issue when trying to install package via pip with python 3.6 on windows. (pip is supposed to work out of the box with this install)
The problem was not running as administrator.
Running cmd as administrator and then installing my package worked:
python -m pip install pylint
I was trying to get pip to work on the 2.7.0 version, but it seems like it doesn't come with the easy_install/pip files (Script folder in main directory), installing 2.7.13 solved the problem for me.
