[Solved] Upgrade django to python 2.7

[Guest Geoff]

I would like django to be upgraded to use python 2.7. (On Stevie) This can be done (supposedly) relatively easily.

 

NOTE: Please do not just copy and paste these commands. I have not verified their safeness.

 

1. Install django:

 

cd /django <-- Directory to where django installation files are located
/path/to/python2.7 ./setup.py install

 

2. Install mod_wsgi

 

cd /mod_wsgi <-- Directory to where mod_wsgi installation files are located
./configure --with-python=/path/to/python2.7
make
make install

This support request is being escalated to our root admin.

I thought djbob already did this? Isn't it something like...

 

#!/usr/bin/python3.2

 

..?

 

Although I don't know any Python myself and I have no idea if that is right. I think it's the same shebang line just with 3.2 on the end.

[Guest Geoff]

Djbob had upgraded the version of python. The version of python that django is running is still 2.4.

[jje]

Oh right - sorry

[Ashoat]

I think that makes sense. You can go ahead and run the commands. Let me know if anything breaks!

[Guest Geoff]

Uh... Just realized that django is not compatible with python 3.x, so I'll just upgrade it to python 2.7

 

Okay, so django installed without any errors.

 

Then, I configured the makefile with python 2.7:

 

root@stevie [/home/gfishing/mod_wsgi-3.3]# ./configure --with-python="/usr/bin/env python2.7"
checking for apxs2... no
checking for apxs... /usr/bin/apxs
checking Apache version... 2.2.16
configure: creating ./config.status
config.status: creating Makefile

 

 

Looking good so far...

root@stevie [/home/gfishing/mod_wsgi-3.3]# make
/usr/bin/apxs -c -I/usr/local/include/python2.7 -DNDEBUG   mod_wsgi.c -L/usr/local/lib -L/usr/local/lib/python2.7/config  -lpython2.7 -lpthread -ldl  -lutil -lm

collect2: ld returned 1 exit status
apxs:Error: Command failed with rc=65536
.
make: *** [mod_wsgi.la] Error 1

 

Then it fails.

 

Okay, I've found the problem:

http://code.google.com/p/modwsgi/wiki/Inst...64_Bit_Packages

[Ashoat]

I could not find instructions on how to install Python 2.7 as a 64-bit library. I tried to recompile/altinstall Python 2.7 with --enable-shared, but I don't see a .so file in /usr/local/lib/python2.7/config/.

[Guest Geoff]

Now I'm getting:

 

./python2.7: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared obje

ct file: No such file or directory

 

Hmm... let me see.

 

Okay, here is the problem:

 

./python2.7: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared obje
ct file: No such file or directory

 

and here is where that file is:

 

/usr/local/lib/libpython2.7.so.1.0

 

The problem is how to make it pick that file up...

 

-------------------------------------------------------------------------------

 

 

I fixed it! Finally. (Only took a couple hours of googling around)

 

Added /usr/local/lib to ld.so.conf

 

Okay, so python2.7 is working correctly now.

 

And the new python version is loaded:

 

mod_wsgi/3.3 Python/2.7.1 Server

[Ashoat]

Cool! I thought I had added /usr/local/lib to ld.so.conf, but I guess I forgot...
