I recently upgraded my macbook to yosemite, and am having trouble starting the google app engine. When I try to run any app, I get a yellow clock, and all options are greyed out.
When I look in GAE prefs, the default python path is
/usr/local/bin/python2.7
but yosemite does not use that location
$ which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
I have tried entering that value in the GAE prefs, but I still get the same issue. I also tried installing the newest ver of python, but it installed in the same loc, with no option to install in /usr/local/bin
Do I need to do something in terms of the symlinks? Has anyone else run across this issue?
thanks,
bp

Hello everyone,
So I have been trying to use Jython to connect to an API Rest and retrieve some information. Now I want to use the Flask Framework with it. I have been trying to install the Flask with Jython but it does not seem to work at all. I am working on a Windows 7 machine and the problem for me is also that I can not download directly from the internet. For all other framework I used python wheels and installed these with Jython which worked fine.
I already tried to following commands and got these errors:
First error that I got was that it could not find the 'init.py' file in the flask folder so I changed the path in the file to the total path. But it just continued to give me more errors.
jython -m pip install '*.whl
Screenshot of the command line ouput of the error
pip install '*.whl (same as above)
I am a little stuck here and I hope that someone has an idea on how to solve this problem.
Big thanks already!!
This appears to be a bug with Jython 2.7.0. See this error report in pip and this one in Jython.
The second of those indicates that it is fixed in the 2.7.1 release candidate.
I installed Python 3.4 on my Mac (OS 10.9.3) and my command for running Google App Engine from the terminal via /usr/local/dev_appengine stopped working. I then (stupidly) did some rather arbitrary things from online help forums and now my Google App Engine itself stopped working as well. When I open it, it says:
Sorry, pieces of GoogleAppEngineLauncher.app appear missing or corrupted, or I can't run python2.5 properly. Output was:
I have tried to delete the application and all related files and reinstall, but nothing has worked for me. It now fails to make the command symlinks as well so when I try to run from terminal I get /usr/local/bin/dev_appserver.py: No such file or directory.
App Engine does not support Python 3.x. Do you still have 2.x installed? Go to your Google App Engine Launcher > Preferences, and make sure you have the proper Python Path to your v2.x. It should be something like "/usr/bin/python2.7"
From Terminal, typewhereis python to help find it. If you know you were using version 2.7, try: whereis python2.7
I've recently downloaded from here the Python GAE, version 1.8.9. After a successfull installation, when I run the GoogleAppEngineLauncher, this is what I get:
as you can see it says that I'm not using the latest version.. but I've installed the latest one, 1.8.9!
Any idea? What am I missing?
Thank you
Months ago, I installed Python 2.7 on my MacBook Pro (OS 10.8.5) and was using IDLE to run programs for classes I was taking on Udacity. One morning IDLE would no longer start, it would just bounce around on the dock and then close. I was eventually able to get things working again by installing Python 3.3 and using that IDLE.
A few days ago, I tried to get 2.7 working again by uninstalling all versions of Python and reinstalling using Macports. (To uninstall, I simply deleted the Python folders in my application folder, the Python.framework file in /Library/Frameworks and some symlinks in /usr/local/bin. Got the idea from another post here: How to uninstall Python 2.7 on a Mac OS X 10.6.4?)
Now no version of Python is working for me. When I try to start IDLE, I get the following error message in the Console:
2/7/14 10:28:02.556 PM com.apple.launchd.peruser.502[151]: ([0x0-0xc80c8].org.python.IDLE[819]) Exited with code: 1
The Python in the terminal still works, by the way. I also tried installing another IDE, PyCharm, but that doesn't work either (I get a message saying No Python interpreter selected)
If you are using a MacPorts Python, you will need to install the corresponding py*-tkinter port to use any Tkinter-based Python app, including IDLE. Try:
sudo port install py27-tkinter
I have Django project which uses postgresql 9. I installed psycopg2 and when I run project I receive 'Error loading psycopg2 module: dll load failed'. I met this issue for the first time. I have windows 7 x64 with python2.7. How can I solve this one?
I had the same problem, it was that psycopg2 does not install well in Windows with _easy_install_, I followed the instructions on the follow SO answer:
Installing psycopg2 (postgresql) in virtualenv on windows
You need to manually install the psycopg2 exe file:
psycopg2-2.4.2.win-amd64-py2.7-pg9.0.4-release.exe
I know this is going to haunt me again or as nwcell puts it:
Every time I need to set up psycopg2 on windows, I wind up wanting to shoot something.
I actually have a machine with it working and I've been at pains to setup another machine. I installed Python 3.8 and the old PC has 3.7.4. The main difference was the file:
C:\project\venv\Lib\site-packages\psycopg2_psycopg.cp37-win32.pyd
On the new PC it was showing as AMD64. I eventually uninstalled 3.8 and reverted back to 3.7.4, then I copied the files from the old PC to the new and then I hit this error:

Going to a WayBackMachine version of the stickpeople:
https://web.archive.org/web/20191003103502/http://www.stickpeople.com/projects/python/win-psycopg/
I didn't install the exe, I simply did a pip install -Iv psycopg2-binary==2.8.4 at which point it started working. So I'm thinking the latest version doesn't work, for me 2.8.4 still works: https://pypi.org/project/psycopg2/#files
It's something to do with x64 as everything I tried with AMD64 didn't work and I spent ages on it.
