我正在基于Debian 9（拉伸）设置新服务器。
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，并且在最近的几天里我一直坚持使用它。
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)]
我尝试使用清单上的ansible_python_interpreter=/usr/bin/python3用python 2和3运行该剧本，但是没有运气。
奇怪的是，如果我在服务器上使用ssh并运行npm install pm2 -g，则可以正常运行。
Nvm在服务器上也可以正常工作。
在达到这一点之前，剧本会安装其他几个软件包：
mongodb
mysql-client
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：

安装节点的全局版本已解决该问题。
