带nvm的不可安装安装节点

Question

我正在寻找一种通过ansible和nvm安装给定版本的节点的方法，nvm的安装工作正常，因为如果我与根用户连接，我可以执行命令understand 8.11.3，但是这个命令不能用于Ansible，我不明白为什么。

---
- name: Install nvm
  git: repo=https://github.com/creationix/nvm.git dest=~/.nvm version=v0.33.11
  tags: nvm

- name: Source nvm in ~/.{{ item }}
  lineinfile: >
      dest=~/.{{ item }}
      line="source ~/.nvm/nvm.sh"
      create=yes
  tags: nvm
  with_items:
    - bashrc
    - profile

- name: Install node and set version
  become: yes
  become_user: root
  shell: nvm install 8.11.3
...

Answer 1

没关系，这是可以工作的配置

- name: Install node and set version
  become: yes
  become_user: root
  shell: "source /root/.nvm/nvm.sh && nvm install 8.11.3" 
  args:
    executable: /bin/bash

Answer 2

我认为你需要输出的线索是：

"/bin/sh: 1: nvm:未找到“

若要运行命令而不包括该命令的完整路径(即nvm而不是/the/dir/nvm/is/installed/in/nvm)，则包含该命令的目录必须位于运行该命令的shell的$PATH环境变量中。

在本例中，与运行交互命令的shell相比，Ansible生成的shell似乎不存在这种情况。更改：

- name: Install node and set version
  become: yes
  become_user: root
  shell: nvm install 8.11.3

至

- name: Install node and set version
  become: yes
  become_user: root
  shell: /full/path/to/nvm install 8.11.3

如果您不知道应该用什么来代替'/full/path/ to '，请尝试：

which nvm

或

find / -name nvm

我只会在这里张贴，因为有数百个这样的帖子。

- name: Install node
    become: true
    become_user: root
    shell: "source /root/.nvm/nvm.sh && nvm install {{ personal_node_version }} && nvm alias default {{ personal_node_version }}"                                 
    args:
      executable: /bin/bash

为我工作过。
