python - Ansible Flask 教程无法安装

Question

我正在关注本教程: http://mattupstate.com/python/devops/2012/08/07/flask-wsgi-application-deployment-with-ubuntu-ansible-nginx-supervisor-and-uwsgi.html

我在 EC2 上安装了 Ubuntu 镜像并尝试运行 playbook，但出现以下错误:

TASK: [install common packages needed for python application development] *****
failed: [54.173.67.23] => (item=libpq-dev,libmysqlclient-dev,libxml2-dev,libjpeg62,libjpeg62-dev,libfreetype6,libfreetype6-dev,zlib1g-dev,mysql-client,python-dev,python-setuptools,python-imaging,python-mysqldb,python-psycopg2,git-core,nginx) => {"failed": true, "item": "libpq-dev,libmysqlclient-dev,libxml2-dev,libjpeg62,libjpeg62-dev,libfreetype6,libfreetype6-dev,zlib1g-dev,mysql-client,python-dev,python-setuptools,python-imaging,python-mysqldb,python-psycopg2,git-core,nginx"}
msg: No package matching '$item' is available
FATAL: all hosts have already failed -- aborting

不确定出了什么问题？

您引用的教程已过时。 Ansible playbook 使用的语法现在无效。试试这个吧

- name: Install python packages
  connection: local
  hosts: 127.0.0.1
  tasks: 
  - name: add nginx ppa
    apt_repository: 
      repo: "ppa:nginx/stable"

  - name: install common packages needed for python application development
    apt: 
      name: "{{ item }}"
    with_items:
      - libpq-dev
      - libmysqlclient-dev
      - libxml2-dev
      - libjpeg62
      - libjpeg62-dev
      - libfreetype6
      - libfreetype6-dev
      - zlib1g-dev
      - mysql-client
      - python-dev
      - python-setuptools
      - python-imaging
      - python-mysqldb
      - python-psycopg2
      - git-core
      - nginx

  - name: install pip
    easy_install: 
      name: pip

  - name: install various libraries with pip
    pip: 
      name: "{{ item }}"
    with_items:
      - virtualenv
      - supervisor
      - uwsgi
