如何向 Popen() 传递多个输入参数？

Question

我正在编写一个为用户安装命令行界面的脚本。

proc = Popen("sudo -S apt-get install vim".split(), stdin=PIPE, stdout=PIPE, stderr=PIPE, shell=True)

# Popen only accepts byte-arrays so you must encode the string

output = proc.communicate(password.encode())

stdoutput = (output)[0].decode('utf-8')

输出：

Installing Vim...|Reading package lists...

Building dependency tree...

Reading state information...

The following additional packages will be installed:

  vim-runtime

Suggested packages:

  ctags vim-doc vim-scripts

The following NEW packages will be installed:

  vim vim-runtime

如您所见，软件包的安装停止Do you want to continue?，并且由于某种原因，安装被中止。

我如何y在这个阶段使用传递 a Popen()？

我已经使用传递密码communicate()，但没有进行多次输入。

-y只需作为选项传递apt-get即可避免与它（进一步）交互的需要。proc = Popen(["sudo", "-S", "apt-get", "-y", "install", "vim"], stdin=PIPE, stdout=PIPE, stderr=PIPE)output, error = proc.communicate(password.encode())stdoutput = output.decode('utf-8')
