Based on your above hints, I try to use the following codes:

output = Popen("""
/bin/bash <<EOF
source ~/.profile.d/environment-module-systems/modules.sh
export PATH=$MODULESHOME/../default/bin:$PATH
module add intel/parallel_studio_xe_2015
env -0
EOF
""", shell=True).stdout

But I meet the following error:

Traceback (most recent call last):
  File "/home/werner/software/hpc/dft-to-study/jasp/jasp.git/jasp/bin/
runjasp.py", line 138, in <module>
    os.environ.update(line.partition('=')[::2] for line in output.split
('\0'))
AttributeError: 'NoneType' object has no attribute 'split'


While the following code will work smoothly:

output = Popen("""
/bin/bash <<EOF
source ~/.profile.d/modules/modules.sh
export PATH=$MODULESHOME/../default/bin:$PATH
module add intel/parallel_studio_xe_2015
env -0
EOF
""", shell=True, stdout=PIPE).communicate()[0]

Any hints on this issue?
