ansible - 尝试使用 ansible 在 vi​​rtualenv 中安装时权限被拒绝

Question

我的 ansible 剧本中有这部剧

- name: Setup virtualenv
  pip: 
    requirements="/vagrant/webapp/requirements/{{ requirements_filename }}" 
    virtualenv="$HOME/.envs/{{ project_name }}"

但是，我收到了 Permission denied 错误。似乎 ansible 正在尝试将软件包安装到系统路径中，而不是安装到 virtualenv 中。

这是完整的追溯:

Storing debug log for failure in /home/vagrant/.pip/pip.log


FATAL: all hosts have already failed -- aborting

Answer 1

我通过明确设置路径而不使用 $HOME 解决了这个问题。多变的。

- name: Setup virtualenv
  pip:
    virtualenv="/home/vagrant/.envs/{{ project_name }}"
    requirements="/vagrant/webapp/requirements/{{ requirements_filename }}"
