Install as non-root user

[ngstigator]

Installing in a vagrant environment. Playbook as follows:

   - role: stephdewit.nvm
      become: yes
      become_user: vagrant
      nvm_shell_init_file: ~/.bashrc

Error log:

TASK [nvm : Install Node.js 12.13.0] *****************************************************************
fatal: [192.168.33.22]: FAILED! => {"changed": true, "cmd": ". ~/.bashrc && nvm install 12.13.0", "delta": "0:00:00.001649", "end": "2019-12-30 18:32:02.526579", "msg": "non-zero return code", "rc": 127, "start": "2019-12-30 18:32:02.524930", "stderr": "/bin/sh: 1: nvm: not found", "stderr_lines": ["/bin/sh: 1: nvm: not found"], "stdout": "", "stdout_lines": []}

nvm is installed for the vagrant user, but installing node fails. Installing node as vagrant user via the command line works as expected.

$ nvm install 12.13.0

Hello.

Sorry for the delay, I had a really busy month.

Except you really need it, you should remove the nvm_shell_init_file: ~/.bashrc line from your playbook. I know it was in the example, and I removed it because it was misleading.

.bashrc is meant for interactive shells and should probably not be used here.

Moreover I did some tests and found that when running with become I had to set the NVM_DIR variable to an absolute path to get everything working. I added an example in the README file.

Let me know if it helps!

Thanks for the commit! The become instructions work as advertised. nvm, node, and npm are all accessible after source ~/.bashrc.
