我正在使用Fabric，并且想使用fexpect。我有以下Python脚本：
from ilogue.fexpect import expect, expecting, run
(...)
def install_postgresql(profile):
print("!!! Installing PostgreSQL...")
print(' -> Doing pre-cleanup...')
# Remove PostgreSQL if it exists
prompts = []
prompts += expect('Do you want to continue [Y/n]? ', 'Y')
with settings(warn_only=True):
with expecting(prompts):
run('sudo apt-get purge postgresql')
print(' -> Doing actual installation...')
# Install PostgreSQL
prompts = []
prompts += expect('Do you want to continue [Y/n]? ', 'Y')
with expecting(prompts):
run('sudo apt-get install postgresql')
# In some cases PostgreSQL has issues with Ubuntu's default kernel params
# that prevent PostgreSQL to start automatically, so we try to start it
# TODO: Fix it
with settings(warn_only=True):
run('sudo service postgresql start')
执行时出现以下错误：
[xxx.xxx.xxx.xxx] out: Traceback (most recent call last):
[xxx.xxx.xxx.xxx] out: File "/tmp/fexpect_MbW3QP6Zpy5KBjBGQcaYxi", line 4, in <module>
[xxx.xxx.xxx.xxx] out: import pexpect
[xxx.xxx.xxx.xxx] out: ImportError: No module named pexpect
我正在使用virtualenv并实际安装了pexpect：
(venv)PALM00545424A:woopup i841712$ pip install pexpect
Requirement already satisfied (use --upgrade to upgrade): pexpect in ./venv/lib/python2.7/site-packages
找到了解决方案。
pexpect不是远程计算机的Python安装的一部分。
我只是执行
sudo -E pip install pexpect
在远程计算机上。
