Hi, When I ran this sample: - expect: command: passwd master responses: (?i)password: “234567” sudo: yes register: hello # name: Debug hello.stdout as part of a string - debug: msg={{ hello.stdout }} # Print all contents of the shell task’s output. - debug: var=hello It threw these exception: TASK [router : expect command=passwd master responses={u’Enter new UNIX password’: u’234567’}] \*\*\* fatal: [147.128.112.106]: FAILED! =\> {“changed”: false, “failed”: true, “msg”: " BECOME-SUCCESS-djevcomgojpacemokygqkwzibvtnyxno Traceback (most recent call last): File "/home/xjigzho\_local/.ansible/tmp/ansible-tmp-1454491175.33-231534496369283/expect", line 2084, in main() File "/home/xjigzho\_local/.ansible/tmp/ansible-tmp-1454491175.33-231534496369283/expect", line 155, in main events=events, cwd=chdir, echo=echo) File "/usr/lib/python2.7/dist-packages/pexpect/ **init**.py", line 224, in runu env=env, \_spawn=spawnu, \*\*kwargs) File "/usr/lib/python2.7/dist-packages/pexpect/ **init**.py", line 233, in \_run cwd=cwd, env=env, \*\*kwargs) File "/usr/lib/python2.7/dist-packages/pexpect/ **init**.py", line 1754, in **init** super(spawnu, self). **init** (\*args, \*\*kwargs) TypeError: **init** () got an unexpected keyword argument ‘echo’ Exception AttributeError: "‘spawnu’ object has no attribute ‘closed’" in \\> ignored ", “parsed”: false} Something wrong with expect module.

It appears you may not be using a new enough version of pexpect. What version do you have installed? ---

Hi Matt, I have updated the pexpect this time, but it still threw this exception: root@073891424fc3:/opt/ansible/ansible/samples# pip install pexpect Downloading/unpacking pexpect **Downloading pexpect-4.0.1.tar.gz** (143kB): 143kB downloaded … Downloading ptyprocess-0.5.1-py2.py3-none-any.whl Installing collected packages: pexpect, ptyprocess Running setup.py install for pexpect File “/usr/local/lib/python2.7/dist-packages/pexpect/async.py”, line 16 transport, pw = yield from asyncio.get\_event\_loop() ^ SyntaxError: invalid syntax Successfully installed pexpect ptyprocess Cleaning up… root@073891424fc3:/opt/ansible/ansible/samples# pip list alabaster (0.7.7) ansible (2.0.0) … … **pexpect (4.0.1)** … … root@073891424fc3:/opt/ansible/ansible/samples# ansible-playbook site.yml -c paramiko PLAY [Generate router configuration files] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* TASK [setup] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ok: [147.128.112.106] TASK [router : expect command=sudo passwd master responses={u’(?i)password’: u’234567’}] \*\*\* fatal: [147.128.112.106]: FAILED! =\> {“changed”: false, “failed”: true, “msg”: “Traceback (most recent call last):\r\n File "/home/xjigzho\_local/.ansible/tmp/ansible-tmp-1454563825.52-194772997459918/expect", line 2084, in \r\n main()\r\n File "/home/xjigzho\_local/.ansible/tmp/ansible-tmp-1454563825.52-194772997459918/expect", line 155, in main\r\n events=events, cwd=chdir, echo=echo)\r\n File "/usr/lib/python2.7/dist-packages/pexpect/ **init**.py", line 224, in runu\r\n env=env, \_spawn=spawnu, \*\*kwargs)\r\n File "/usr/lib/python2.7/dist-packages/pexpect/ **init**.py", line 233, in \_run\r\n cwd=cwd, env=env, \*\*kwargs)\r\n File "/usr/lib/python2.7/dist-packages/pexpect/ **init**.py", line 1754, in **init** \r\n super(spawnu, self). **init** (\*args, \*\*kwargs)\r\nTypeError: **init** () got an unexpected keyword argument ‘echo’\r\nException AttributeError: "‘spawnu’ object has no attribute ‘closed’" in \\> ignored\r\n”, “parsed”: false} PLAY RECAP \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* 147.128.112.106 : ok=1 changed=0 unreachable=0 failed=1 BRs/Jay 2016/2/4 Thursday UTC+8AM10:41:31，Matt Martz reply： ---

When you upgraded it put pexpect in /usr/local/lib however the error from your Ansible run indicates that pexpect was used from /usr/lib Also, make sure you are upgrading pexpect on the remote target machine. ---

Hi Matt. I have reinstalled ansible and pexpect and then it works. I appreciate your comments and help. Thanks.
