Question

我正在使用Ansible的pip模块从requirements.txt文件安装我的应用程序依赖项。它绝对有效，从列表中下载并安装每个软件包，但当它特别到达时，它将失败导致整个ansible-playbook失败并出现Ascii unicode错误。

Ansible-Playbook任务

- name: Install project requirements
  pip:
    state: latest
    requirements: "{{ project_path }}/requirements/base.txt"
    virtualenv: "{{ venv_path }}"
    virtualenv_python: python3.6
    virtualenv_command: /usr/local/bin/virtualenv

Ansible Message

Answer 1

基于django-s3direct的代码，它尝试读取README.md，它似乎是用UTF8编码的。它失败了，因为python试图用ascii编解码器读取它。

尝试更改python的默认编码，在控制台中运行此命令以设置env变量：

export PYTHONIOENCODING=utf8

编辑：由于错误出现在访客上，请在您的剧本中设置env变量：http://docs.ansible.com/ansible/latest/playbooks_environment.html

- name: Install project requirements
  pip:
      environment:
        PYTHONIOENCODING: utf8

Ansible pip模块发出读取requirements.txt文件
