Clean up readme structure a bit to help with readability. fix
instructions which could lead to a sourcing loop if misinterpreted.
guidance should direct macos users to simply copy the source snippet
manually into their desired profile file.
Resolve#2123
Adds the following information to the "Migrating global packages while installing" section:
- notification that the npm package is explicitly not updated when using the --reinstall-packages-from flag
- information about the --latest-npm flag
- recovery instructions if a user has already updated node with an incompatible npm version
- Operating system and version: Mac OS X Mojave
- What happened? $NVM_DIR was set to nvm
- What did you expect to happen? $NVM_DIR should be set to .nvm
I added the following line from the README to my .zshrc:
```
export NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/.}nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
```
I couldn't figure out why nvm wasn't loading, until I realized that
`echo NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/.}nvm"` outputs `NVM_DIR=nvm`.
Changing the line to `export NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/}.nvm"` fixed the problem. This outputs `NVM_DIR=.nvm` as expected. I tested this and the same behavior holds true in Bash as well.
It was trying to read ./.nvmrc if you cd'ed into a subdirectory of the directory that has .nvmrc, which would give print `-bash: ./.nvmrc: No such file or directory` to stderr and potentially not doing the `nvm install`.
Add Ansible task example to show how to install nvm and update it.
Ansible is a systems administration tool.
See https://github.com/ansible/ansible
My personal experience of `nvm` is that installing via Ansible is good, and that a good example can help. This example took me about an hour to learn, so I'm hoping to save other people some time. This example is somewhat different than any others that I found on the web. There may be a better way to write it, and if so, please improve it.
- Lists should be surrounded by blank lines
- Use only `1.` for ordered list item prefix
- Starting bulleted lists at the beginning of the line
- Fenced code blocks should be surrounded by blank lines
