python 中的子进程不允许读取

Question

我需要你的帮助来调试一些东西我在 python 中使用子进程到运行带有此命令的外部应用程序

subprocess.run(["Program", "-o", "-e", "Desktop",new_path])

new_path 是一个变量，我在其中存储应用程序的路径。所以它看起来很好但是当我用 python3 main.py 启动应用程序时我得到

 File "C:\Python27\lib\site-packages\run\__init__.py", line 145, in __new__
process = cls.create_process(command, stdin, cwd=cwd, env=env, shell=shell)

 File "C:\Python27\lib\site-packages\run\__init__.py", line 121, in create_process
shlex.split(command),

 File "C:\Python27\lib\shlex.py", line 279, in split
return list(lex)

 File "C:\Python27\lib\shlex.py", line 269, in next
token = self.get_token()

File "C:\Python27\lib\shlex.py", line 96, in get_token
raw = self.read_token()


File "C:\Python27\lib\shlex.py", line 124, in read_token
nextchar = self.instream.read(1)

AttributeError: 'list' object has no attribute 'read'

Answer 1

运行带有 shell=True

的子进程

subprocess.run(["Program", "-o", "-e", "Desktop",new_path], shell=True)

python 中的子进程不允许读取

Subprocess in python don't allow read
