[issue15066] make install error: ImportError: No module named _struct

[Irit Katriel]

Irit Katriel  added the comment:

Lib/site.py has changed a lot in the meantime compared to the patch that 
Antonio mentioned.

Unless you are currently seeing this issue with 3.9+ I suggest we close this 
and let a new issue be opened if someone does see this problem on a current 
version.

[issue15066] make install error: ImportError: No module named _struct

[Antonio Chay]

Antonio Chay added the comment:

Hello there!
I have the same issue, using CentOS 5.8, I *reversed* this patch:

http://bugs.python.org/issue8205

and now make install works.

A side note: before it failed to compile _multiprocessing, with the patch 
reversed now is included.

HTH.
Regards!

Thank for your attention.

I try it:

Traceback (most recent call last):

ImportError: No module named _struct   1

And I read the log of make, it seems to be compiled OK:

_struct.o and _struct.so are just there, I truely don't know what's wrong.
Newly to Python, I think python should not have such an installation problem.



I installed it(2.7.3) on RHEL5, works OK, but I want to install OpenSSL to it, 
don't know how to do it, so I learn to install it on SUSE in my workplace while 
RHEL5 is in another place. 

RHEL5 has python 2.4.2, in my memory. SUSE12 has python 2.7.2.

Does system's python affect my installtion? But I think it shouldn't.



In fact, long before I downloaded a compressed package named 
Python-2.7.3.tar.bz2, with this one, I can make  make install, but I can't 
run it, error is:

suzc@linux-opensuse:22:12:31:bin$ ./python2.7

raise IOError(msg)
IOError: invalid Python installation: unable to open 
/WORK/suzc/installed/python 
   /lib/python2.7/config/Makefile (No such file 
or directory)   

I'm crazy about this, I search it in google, no satisfatory answers. So I want 
to download a new one 2.7.3, and install, but i just can not install it.

Thanks again.

[issue15066] make install error: ImportError: No module named _struct

[Ned Deily]

Ned Deily n...@acm.org added the comment:

I have no experience with opensuse but, from a general unix install install 
view, the most obvious cause of that message would be a build failure of the 
_struct extension.  Check the log file for messages with _struct in it.  You 
could also try to check the paths and to import it in the build directory:

PYTHONPATH=/WORK/suzc/installed/python/lib/python2.7 \
 ./python -c 'import sys; print(sys.paths)'
PYTHONPATH=/WORK/suzc/installed/python/lib/python2.7 \
 ./python -c 'import _struct; print(_struct.__file__)'
