So the longer answer is that only certain directories are searched by
Linux for shared libraries. Python happens to provide a shared library,
which it depends on, which is installed by the source tarball in /opt
along with the binaries. There are a number of ways you can solve this:
- Create a file in /etc/ld.so.conf.d/python2.7.conf and place in it the
- before running /opt/python2.7/bin/python2.7, set the LD_LIBRARY_PATH
environment variable (example in bash):
$ LD_LIBRARY_PATH=/opt/python2.7/lib /opt/python2.7/bin/python2.7
- create a wrapper script in /usr/bin that sets LD_LIBRARY_PATH and
I recommend the first as a permanent solution.
