subprocess.Popen和py2exe

Question

我正在使用包装器库将命令发送到Windows可执行文件，并且python脚本运行良好。

但是当我用py2exe转换脚本时，我从生成的进程中得到错误，说明相应的命令不存在。

process = subprocess.Popen(args, 
    stdin=subprocess.PIPE, 
    stdout=subprocess.PIPE, 
    stderr=subprocess.PIPE
)

有些命令毫发无损地到达，直到其中一个命令缺少第一个字母。

process.stdin.write(data)
process.stdin.flush()

如果是发送命令

  

未知动作：ommand
