[ESPResSo-users] Installation problem

Hi everyone, 
I am trying install espresso 4.0.2 with python 3. The cmake command could be executed successfully, but when I tried to compile the source code, I got errors below:

[ 61%] Generating code_info.pyx
Fatal Python error: Py_Initialize: can't initialize sys standard streams
Traceback (most recent call last):
  File "/home/shawn/sourcecode/espresso/src/python/espressomd/io/", line 17, in <module>
  File "/home/shawn/sourcecode/espresso/src/python/espressomd/io/writer/", line 17, in <module>

make[1]: *** [src/python/espressomd/CMakeFiles/code_info.dir/all] Error 2
make: *** [all] Error 2

It's so confusing, because I can successfully install espresso with python 2 on the same computer and I can also install espresso with python 3 on another computer.

Does anyone know how to fix this? Thank you very much.
