无法在 Debian 伸展的 Ansible 2.7 上使用 NPM 包安装 PM2

Question

我正在建立一个基于 Debian 9 (stretch) 的新服务器。

我有一个 Ansible 剧本，当我尝试使用 npm ansible 模块安装 PM2 时，它失败了，我在过去几天一直被这个问题困扰。

我正在使用 ansible 2.7：

ansible 2.7.10
  config file = None
  configured module search path = ['/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python3.7/site-packages/ansible
  executable location = /usr/local/bin/ansible
  python version = 3.7.3 (default, Mar 27 2019, 09:23:15) [Clang 10.0.1 (clang-1001.0.46.3)]

我尝试在 Inventory 上使用 ansible_python_interpreter=/usr/bin/python3 运行带有 python 2 和 3 的剧本，但没有成功。

奇怪的是，如果我在服务器上 ssh 并运行npm install pm2 -g，它就可以正常工作。 Nvm 在服务器上也能正常工作。

在达到这一点之前，剧本会安装其他几个包：

• mongodb

• mysql 客户端

• redis

• 各种库

• 等

这是剧本的摘录

tasks:
     ...

     - name: Install nvm
      sudo: no
      git: repo=https://github.com/creationix/nvm.git dest=~/.nvm version={{ NVM_VERSION }}
      tags: nvm

    - name: Source nvm in ~/.profile
      sudo: no
      lineinfile: >
        dest=~/.profile
        line="source ~/.nvm/nvm.sh"
        create=yes
      tags: nvm

    - name: Install versions
      shell: bash -lc "nvm install {{ item }}"
      register: output
      changed_when: "'already installed.' not in output.stderr"
      with_items: "{{ NVM_NODE_VERSIONS }}"
      sudo: no

    - name: Set default node version to {{ NVM_DEFAULT_NODE_VERSION }}
      command: sudo -iu admin nvm alias default {{ NVM_DEFAULT_NODE_VERSION }}
      tags: nvm

    - name: Install PM2 packages
      npm:
        executable: /home/admin/.nvm/versions/node/v{{ NVM_DEFAULT_NODE_VERSION }}/bin/npm
        name: pm2
        global: yes
        state: present

....

变量定义如下：

NVM_VERSION : "v0.33.0"
NVM_INSTALL_SCRIPT : "/home/admin/nvm_install.sh"
NVM_NODE_VERSIONS :
 - v10.15.3
 - v6.9.4
 - v8.10.0
 - v8.11.1
NVM_DEFAULT_NODE_VERSION: "10.15.3"

这是我得到的错误：

更清晰的错误：

安装全局版本的node已经解决了这个问题。
