Getdefaultlocale returns None when running sync.db in a Django project in PyCharm

OSX 10.7.3, PyCharm version 2.5 build PY 117.200

I will check how I get the error:

  • I am starting a new project
  • Create a new VirtualEnv and select Python 2.7 as the base interpreter (leave global packages inherit unchecked)
  • Click "Install" and select Django v1.4
  • Choose Django Project Type
  • Tick Enable Admin
  • Open settings.py and add sqlite3 to DATABASES:ENGINE
  • Run sync.db
  • Get the opportunity to create a superuser database
  • locale error

The problem is that the getdefaultlocale () method returns nothing (well, no).

 return getpass.getuser().decode(locale.getdefaultlocale()[1]) TypeError: decode() argument 1 must be string, not None

However, if I turned on virtualenv workon MyApplication and ran python with the following code:

 Python 2.7.2 (default, Feb 7 2012, 23:16:02) [GCC 4.2.1 Compatible Apple Clang 3.0 (tags/Apple/clang-211.10.1)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import locale >>> print locale.getdefaultlocale() ('en_GB', 'UTF-8')

Does anyone know what is going on?

The main reason for this is because PyCharm does not have access to environment variables by default.

I found 3 solutions to this problem:

  • Set the global environment variable using the CrazyCoder link in the comments on this question.

  • Launch PyCharm from the terminal window by going to the PyCharm application directory and running ./pycharm (maybe create a symbolic link in your PATH to make this less inconvenient)

  • Open PyCharm settings, go to Console > Django Console , enter the required environment variables, as in your bash profile, for example. LC_ALL=en_US.UTF-8

I would suggest the 3rd way as the most elegant, although it was annoying that variables are not loaded by default.

Go to terminal:

 $ nano .bash_profile

add:

 export LC_ALL=en_GB.UTF-8 export LANG=en_GB.UTF-8

(or use the locale -a command to see which ones are available to you)

save and try again.
