I have read that python will compile the source file .py by itself to produce .pyc, but this doesn't happen in my case. I have the source file inside /opt/osqa folder where I always have to use sudo privileges.

How can I compile this source file manually. I am using ArchLinux. Do I need any specific package?

  • Can you give an example on how are you compiling. Which version of python are you using? – mkc Dec 4 '13 at 21:57
  • try python -mcompileall – jfs Dec 16 '13 at 0:38

The .pyc files are created when files are imported. Usually running a script by itself will not create a compiled file. For instance:

% cat tmp.py
print 'in tmp.py'

When I run the file normally:

% python tmp.py 
in tmp.py

there is no .pyc file created:

% ls tmp.py*

However, if I import tmp from a live Python interpreter:

% python
Python 2.7.6 (default, Nov 14 2013, 09:55:56) 
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.2.79)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tmp
in tmp.py

then the compiled file is created:

% ls tmp.py*
tmp.py  tmp.pyc

So, it may be normal behaviour depending on how you are running your script.

  • I opened python by sudo python and then executed import settings_style.py the compilation began but I got an error. Well as it conserns me this question is solved... – 71GA Dec 5 '13 at 6:28

I suspect the .pyc files are not being created because of permission settings in the directory that you have your python sources. See this for more info: http://effbot.org/pyfaq/how-do-i-create-a-pyc-file.htm

  • I was thinking of this too. This is why I also mentioned it. I have also read the link you posted but i have no py command mentioned in the link. So do i need any speciffic package for this? There is no package py in the official repo archlinux.org/packages/… and none in AUR repo aur.archlinux.org/packages/?O=0&K=py – 71GA Dec 4 '13 at 22:17
  • Try copying the python code to your home directory and compile. Just use normal python yourcode.py and see if yourcode.pyc gets created. – mkc Dec 4 '13 at 22:23
  • I tried and the compilation started but was terminated because the source file was moved and was therefore not finding the other dependant source files. I ll have to find a way t ocompile it in the folder as is. Will try changing the folder rights to 777 and see what happens. – 71GA Dec 5 '13 at 6:21
