python: error while loading shared libraries: libpython3.4m.so.1.0: cannot open shared object file: No such file or directory

I have created a python virtual environment using virtualenv, after activating it, I can see where is Python installed in my shell as following:

(virtualenv-test) bash-4.1$ whereis python
python: /usr/bin/python2.6 /usr/bin/python2.6-config /usr/bin/python
/usr/lib/python2.6 /usr/lib64/python2.6 /usr/X11R6/bin/python2.6
/usr/X11R6/bin/python2.6-config /usr/X11R6/bin/python
/usr/bin/X11/python2.6 /usr/bin/X11/python2.6-config
/usr/bin/X11/python /usr/include/python2.6
/usr/share/man/man1/python.1.gz

Also I can see what python version I’m using: 

(virtualenv-test) bash-4.1$ which python
/data/virtualenv-test/bin/python

However, after typing python, I got the following error message:

(virtualenv-test) bash-4.1$ python
python: error while loading shared libraries: libpython3.4m.so.1.0: cannot open shared object file: No such file or directory

What can be the underlying reason?

pythonpython-3.xvirtualenv

      Try adding the python3.4’s lib path to the $LD_LIBRARY_PATH environment variable.

      First find out the lib path of python3.4 (depends on how you installed python3.4)

      For me it was: /opt/python361/lib, then add it to environment variable like so:

      export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/python361/lib

      P.S.
      I came across a similar problem while using virtualenv with python3.6, and I fixed it like so:

      • First, append include <lib path of python3.x> to /etc/ld.so.conf (Something like: include /opt/python361/lib or include /usr/local/lib)
      • Then, activate the new configuration by running sudo /sbin/ldconfig -v.
