当我尝试 chown 目录时，Fabric 给了我一个 EOFError。仅当我从 fabric 之前立即运行的 python 脚本运行子进程时才会发生这种情况。

从我的fabfile：

...
with settings(warn_only=True):
    run('python my_scripts/import_local.py')
sudo('chown www-data:www-data /opt/mm/my_project/uploads -R')

如果我将下面的行注释掉，my_scripts/import_local.py我不会收到任何错误：

    p = subprocess.Popen(command.split(), stdout=subprocess.PIPE,
                         stderr=subprocess.PIPE)
    result = p.communicate()[0].splitlines()
    if result:
        print result

使用留下的子进程行，我得到了这个回溯（使用 --show=debug 运行）：

[xx.xx.xxx.xxx] sudo: sudo -S -p 'sudo password:'  /bin/bash -l -c "cd /opt/mm/my_project/current && source environment.sh && chown www-data:www-data /opt/mm/my_project/uploads -R"

运行时会发生什么：

$ ssh xx.xx.xxx.xxx -t'sudo -S -p "sudo password:"  /bin/bash -l -c "cd /opt/mm/my_project/current && source environment.sh && chown www-data:www-data /opt/mm/my_project/uploads -R"'
