Mac OS X /bin/bash: python: command not found in some IDE

When I compiled test.py(a very simple Python file) in Sublime Text or CodeRunner, I got the error:/bin/bash: python: command not found. Then I input python test.py in the Terminal app, it worked. Later I downloaded Pycharm and compiled the file again, it worked too!
So I assume there is some kind of path setting or something else that was not set correctly. I've searched for quite a long time on the internet but no use. Please help or try to give some ideas how to solve the problem.
Here are some details:
I've tried inserting #! /usr/bin/python at the top of test.py file but no use
The output of echo "$PATH" in Terminal is /usr/local/sbin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin:/Users/chenyang/Downloads/android-sdk-macosx/platform-tools
I've found several versions of Python in my macbook :2.6, 2.7, 3.2, 3.3, 3.5. Under the folder /System/Library/Frameworks/Python.framework/Versions I found 2.6, 2.7. Under the folder /Library/Frameworks/Python.framework/Versions I found 3.2, 3,3, 3.5.
I've solved the problem myself and post the answer below

The Terminal loads a number of files that can modify your PATH variable, including ~/.profile, ~/.bashrc, ~/.bash_profile, etc. These do not get loaded when the Mac OS X system UI is started / when you login to your user profile via the Finder app. Consequently, apps started via Finder do not inherit the PATH and other environment variables set in these files.
Different versions of Mac OS X have different solutions for setting environment variables such that they are loaded by Finder. Older versions of Mac OS X supported a file called ~/.MacOSX/environment.plist that could be used to specify the environment. Newer versions of OS X use the launchctl tool to set environment variables that are seen by apps started with launchctl (which is responsible for starting the system UI and other system services).
In short, use the command:
launchctl setenv <variable-name> <variable-value>
To set this environment variable for the current user. Apps run as the current user will inherit the variables that are specified. So, for example, you could do:
launchctl setenv PATH "$PATH"
... from the Terminal to apply your current PATH value to the system for your account.

Thank everyone who helps. I've solved the problem myself.
I've always been using zsh instead of bash. After updating CodeRunner to the newest version, the app uses bash by default. So I just need go to Preference>Advanced menu and untick the checkbox invoke bash in login mode when running code to solve the problem.
In Sublime Text3, the solution is in this link:https://stackoverflow.com/a/38574286/6631854

django-admin.py startproject mysite is not doing anything

It worked when I did the poll tutorial in linux, but I'm doing it again in Windows 7, and it does nothing.
I already set the environmental variables, and set the file association to my python27.exe
When I run django-admin.py startproject mysite from the DOS command prompt, it executes, but it's showing me all the information (Like the options, etc) as though I typed the help option instead. It's not actually creating project files in my directory. I appreciate the help.
also, I tried the solution found here (it appears to be the exact same problem).
It did not work
django-admin.py is not working properly

I ran into the same problem.
Never having worked with Django before but having worked with Python 2.7 a fair bit, all on a windows 7 platform. I downloaded the latest version of Django and unpacked it on my desktop.
After mucking around a bit managed to get it to install itself. I found could not just follow the tutorial thats provided in the docs googled the problem and found this thread, now I was able to get it to work by doing the following things,
I work with a dos command window open. I navigate to the root of where I want the project file to be set up. I then ensure that the django_admin file has been editted as per wynston's instructions and then typed the following.
python c:\location of django_admin.py startproject projectname
and it executed beautifully.
*Thanks to wynston for the edit to the django_admin.py file.

Try to run python27 django-admin.py startproject mysite from the command line,maybe a different (older) python.exe executes the django-admin.py file. If there's a program associated to the .py files, things mixes up, and your path environment variable doesn't matter.
I suggest you to use virtualenv. When you use it, you should put the python.exe before every .py file you want to run, because the install of python will associate .py files to the installed python.exe, and will use that, whatever is in your path. :(

Change the first line of django-admin.py #!/usr/bin/env python to for example
#!D:\Program Files\Python\python.exe (Where you install your python.exe,that's my directory), it works.

Use python django-admin.py startproject mysite. That worked for me some time ago when I had the same issue.

The solution is simple in Windows:
1-Go to C: \ Python34 \ Scripts
2-Right click on django-admin.py
3-Select open with
4-Select default program
5-Select Laucher Python for Windows (Console)
6- Run the command in CMD Windows python django-admin.py startproject mysite

Great answers. But unfortunately it did not work for me. This is how I solved it
Opened django_admin.py as #wynston said. But the path at first line was already showing #!C:\ correctly. So did not had to change it
I had to put "..." around django-admin.py address. Navigated to the project directory in cmd.exe and ran this
python "C:\Users\ ......\Scripts\django-admin.py" startproject projectname
It worked only with the quotation marks. I am using Anaconda Python 2.7 64 bit, on Windows 7, 64 bit. Hope it helps

Django is not accepting arguments in Windows

I have installed django on my windows vista computer and can add the django library to a python script, but cannot seem to ge teh following to work correctly from the command line:
django-admin.py startproject mysite
When I try to run this or the help command I always get the default message that shows all the commands as if I did not send it the second argument.
Any ideas on how to resolve this issue?

try
python django-admin.py startproject mysite
you may cd to the dir which the django-admin.py in

The biggest headache I've run into with developing on Windows is path issues. I use virtualenv and David Marble's port of virtualenvwrapper As such, I fully qualify the path to django-admin.py. Of course, the virtualenv's site-packages could get added to my PATH, but I find it just as easy to just paste in the path.
Try fully qualifying the path to django-admin.py and see if that gets you going.

If python variable environment is set you should try something like
python Path\to\django\installation\bin\django-admin.py startproject mysite

FYI, I figured out the issue based on another thread I found here:
Windows is not passing command line arguments to Python programs executed from the shell
The issue was about how the registry was handling my calls to admin.py and the fact that it was dropping the arguments I passed.
Hope this helps others who run into this issue.

How to make Python knows the path to look for .py files?

Just started trying to learn Python and Django today. Following their documentations I was able to install Python and Django and got them up and running. I'm running Apache 2.2 on on Windows 7 by the way.
I got to the part in the official tutorial that tells me to cd to the directory I want for my project and run this command
django-admin.py startproject mysite
However I can't just run that command as is. I need to run it like this
python c:\Python27\Scripts\django-admin.py startproject mysite
Am I suppose to type out the whole thing like this? Or is there some settings I miss that will let me run the .py file without the python C:\Python27\Scripts\ part in front?

If you want to just be able to type django-admin.py, two things need to be set up:
The directory containing it needs to be in your PATH.
You need to make sure that the .py extension is associated with the Python interpreter. This is normally done during the installation of Python.

Try running:
python django-admin.py startproject mysite
If that don't work, try adding C:\Python27\ to the command search path

How to integrate Django and Cygwin?

I have a Windows box with cygwin, python and django installed.
Now I want to run django-admin, but when I do I get the error:
$ django-admin.py
c:\Python26\python.exe: can't open file '/usr/bin/django-admin.py': [Errno 2] No such file or directory

From here
For Windows users, who do not have symlinking functionality available, you can copy django-admin.py to a location on your existing path or edit the PATH settings (under Settings - Control Panel - System - Advanced - Environment...) to point to its installed location.
hope this helps

I just ran into the exact same problem. I've found that if you already have the windows version of python installed, it seems to get priority over the cygwin version. I solved the problem by editing /etc/profile and changed:
PATH=/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:$PATH
...to:
PATH=/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:
...which I think stops cygwin from adding the normal windows path. Once you've got that working, download django into some directory, move into that directory and type:
python setup.py install
I was having problems to begin with because I had omitted the 'python' bit at the start

As for the step on how to start your django in cygwin
first open your windows command prompt
then register the python environment by doing this:
Path %path%;C:\Python27;C:\Python27\Scripts
then now go to the installation folder of your cygwin
cd C:\cygwin
then run the cygwin.bat like this:
C:\cygwin>cygwin.bat <enter>
then cygwin will open, and type python to see if it now working
$ python
Voila we are done!

Sort of sounds like the windows version of Python is trying to run instead of the cygwin one. What happens if you type this:
$ python django-admin.py
Here I'm assuming
$ which python
Finds the cygwin version of python (which will be something like /usr/bin/python).
You may also try (temporarily) uninstalling the windows version of python and use only cygwin.

Help us help you. Is there a reason why you are running the windows python interpreter (c:\Python26\python.exe) as oppose to the cygwin python interpreter (/usr/bin/python.exe)? That could be your problem. So to troubleshoot that, you might consider removing the windows native interpreter or simply making sure the cygwin path is listed before the c:\Python26 path in the windows global PATH variable.

Add the location of your django/bin folder (or wherever else you keep django-admin.py) to your PYTHONPATH environment variable.

Like Brian mentioned you are running the Windows version of Python which won't work with the Cygwin installation.
A word of warning. When I first started using Django, I tried installing it in Cygwin and had a variety of problems and ended up switching to the regular Windows version of Python. Unfortunately, I didn't document all my issues, but I remember some of them had to do with the database libraries. Anyway, that was a few months ago when I knew less about Django than I do now. Maybe the problems I ran into have been solved and perhaps now that I know more I could get it to work, but running Django on Cygwin does seem to be the road less traveled. Good luck. :)

Just copy the django-admin.py to the current location you are working on for e.g
on Cygwin:
<root>/projects/
on your windows directory it will look like this:
C:\cygwin\home\<your computer name>\projects\
once you copy the file, you can create your project by typing this command:
$ python django-admin.py startproject mysite
and that's all - you have completed your first project using the Cygwin linux-like environment.

Add two lines to .bash_profile and .bashrc files (view their difference here). You can find them in C:\cygwin\home\[username]:
export PATH=$PATH:/cygdrive/c/python2.7
export PYTHONPATH=$PYTHONPATH:/cygdrive/c/python2.7/Lib/site-packages
Hope this helps
