Python Pexpect期望获取timedout错误

Question

expect功能已超时。我张贴我的代码和手动完成时的步骤

import pexpect
from pexpect import popen_spawn
child = popen_spawn.PopenSpawn('tibemsadmin -server localhost:7222 -user admin -password admin', cwd='C:/tibco/ems/8.5 - Copy/bin')
out = child.sendline('delete queue zzzzzzz')
child.expect('Are you sure (yes,no)?')
print(out)

手动完成时：

C:\tibco\ems\8.5 - Copy\bin>tibemsadmin -server localhost:7222 -user admin -password admin
