【问题描述】：

所以问题基本上很简单 - npm install 在我通过 Ansible 设置的 Vagrant 上不起作用，但是当我从控制台运行它时效果很好

案例 1) 我有一些带有线条的剧本：

... 
- name: install frontend libs
  npm: path=/vagrant/frontend/bem
...

当我运行 vagrant provision 时，当涉及到这一点时，它会崩溃 superbad：

TASK: [nodejs | install frontend libs] **************************************** 
failed: [default] => {"cmd": "/usr/bin/npm install", "failed": true, "rc": 50}

当我在 node_modules 文件夹中查找权限时，它具有 drwxr-xr-x 权限。

案例 2) 当我转到我的虚拟机并手动运行 npm install 时，它工作正常，并且 node_modules 权限是 drwxrwxr-x。

那么问题 - 我怎样才能通过 ansible 实现相同的行为？

【问题讨论】：

看起来是 umask 的问题。

【解决方案1】：

您使用哪个用户运行此 npm 命令？您可能希望以其他用户身份运行它：

- name: install frontend libs
  npm: path=/vagrant/frontend/bem
  sudo: yes
  sudo_user: someuser
