如何避免在非交互模式下运行（python子流程.Popen)

Question

当我使用子流程.Popen要运行cts，它总是进入非交互模式，然后停止。在

Non-interactive mode: Running initial command then exiting.

下面是我使用的代码。在

subprocess.Popen(command_list, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

Android CTS 5.1_r5 Non-interactive mode: Running initial command then exiting.
