Hello,
I am running gromacs commands on Putty and when I use:
python MmPbSaStat.py -m energy_MM.xvg -p polar.xvg -a apolar.xvg
I get an error that there is "No module named builtins" Now, when I try to install it using
pip install future
I get the following error:
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6.
Pip is accessing this path: /usr/lib/python2.6/site-packages/pip/. So, there indeed is a python 2.6 installed in the path usr/lib but in my bashrc, I have the correct path to updated python3.7 as shown in the image below:
why isn't that being read? Can someone please help? Linux is very new to me. Thank you!
Try running your original command with python3 instead if python. If that fails again with a similar message, try to update like this:
python3 -m pip install future
It will install the missing packages in your python3 directory. It may also work if you use pip3 instead of pip in your original update command.
Dear @Mensur Dlakic all three approaches are generating the same error: error while loading shared libraries: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory
Check the python libraries path by locate libpython3.7m. In general, they would be in /usr/local/lib. If so, try this (in bash shell): export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib:$PATH:. If this works, then run sudo ldconfig /usr/local/lib. If the libraries are not located in standard location, change /usr/local/lib with appropriate location. If you don't get a path, try installing libpython3.7 (sudo apt-get install libpython3.7 in ubuntu/debian/mint)
