我需要设置我的服务器。我是以下的ansible剧本。
---
- hosts: webservers
user: root
sudo: yes
tasks:
- name: add nginx ppa
action: apt_repository repo=ppa:nginx/stable state=present
- name: install common packages needed for python application development
action: apt pkg=$item state=installed
with_items:
- libpq-dev
- libmysqlclient-dev
- libxml2-dev
- libxslt1-dev
- mysql-client
- python-dev
- python-setuptools
- python-mysqldb
- build-essential
- git
- nginx
- name: install pip
action: easy_install name=pip
- name: install various libraries with pip
action: pip name=$item state=present
with_items:
- uwsgi
handlers:
- name: restart nginx
service: name=nginx state=restarted
当我运行此脚本时，以下是输出

我已将this链接称为相同的链接。
我是ansible的新手并且不理解错误，因为with_items中提供的包名中没有拼写错误。 错误究竟是什么？
答案 0 :(得分：10)
