Hi all, Based on the methods here:
http://stackoverflow.com/questions/7040592/calling-the-source-command- from-subprocess-popen/18897007#comment30954741_12708396 I use the following code the update the os.environ: import os from subprocess import check_output # POSIX: name shall not contain '=', value doesn't contain '\0' output = check_output("source /home/werner/env-intel-toolchains.sh; env -0", shell=True, executable="/bin/bash") # replace env os.environ.clear() os.environ.update(line.partition('=')[::2] for line in output.split('\0')) In the above code, the file /home/werner/env-intel-toolchains.sh will be sourced and its settings should be combined into the current os.environ of python. But, I find that the above code will fail on the `os.environ.clear()' command as follows: In[24]: import os from subprocess import check_output # POSIX: name shall not contain '=', value doesn't contain '\0' output = check_output("source /home/werner/env-intel-toolchains.sh; env -0", shell=True, executable="/bin/bash") # replace env os.environ.clear() os.environ.update(line.partition('=')[::2] for line in output.split('\0')) Traceback (most recent call last): File "/home/werner/anaconda2/lib/python2.7/site-packages/IPython/core/ interactiveshell.py", line 3066, in run_code exec(code_obj, self.user_global_ns, self.user_ns) File "<ipython-input-24-816c472b62f2>", line 10, in <module> os.environ.clear() File "/home/werner/anaconda2/lib/python2.7/os.py", line 501, in clear unsetenv(key) OSError: [Errno 22] Invalid argument If I don't use the `os.environ.clear()' code line, it will work smoothly.
