installation / python versions

[Anonymous]

Hi,

I would like to install PyRosetta4 for python 3.6 on Ubuntu 16.04 64bit. For this I installed python3.6, as deafault python version was 2.7. According the installation instruction I have to use smth like

cd setup && sudo python setup.py install

Will it call python 2.7? should I expect any errors? How should I install PyRosetta properly?

Thanks!

Hi again!

Sorry, previous question was probably too obvious, but when trying

cd setup && sudo python3.6 setup.py install

I’ve got an error “OSError: Could not build the egg.”

(I am trying to install PyRosetta4 for python 3.6 on Ubuntu 16.04 64bit.)

I would be grateful for your advice.

Checking with others, it seems this typically happens when you try to build with one version of Python and install with another.

To fix it, delete the PyRosetta build directory (which can be found by re-running with –print) and then redo the installation with a single, consistent version of Python. (Use the same version for both build.py and setup.py)
