                  问题描述

                  我有一些自定义命令.

                  # works 
                  subprocess.Popen(['python'], stdout=subprocess.PIPE)
                  

                  但如果我有自己的系统命令,例如 deactivate,我会收到该错误

                  But if I have my own system commands like deactivate, I get that error

                  Traceback (most recent call last):
                    File "runner2.py", line 21, in <module>
                      main() 
                    File "runner2.py", line 18, in main
                      subprocess.Popen(['deactivate',], stdout=subprocess.PIPE)
                    File "/usr/lib/python2.6/subprocess.py", line 633, in __init__
                      errread, errwrite)
                    File "/usr/lib/python2.6/subprocess.py", line 1139, in _execute_child
                      raise child_exception
                  OSError: [Errno 2] No such file or directory
                  

                  更不用说我需要在我的沙盒 virtualenv 下执行这个了.

                  Let alone I need to execute this under my sandbox virtualenv.

                  推荐答案

                  尝试在 Popen 调用中添加一个额外的参数 shell=True.

                  Try add an extra parameter shell=True to the Popen call.
