Manage your framework versions in a simple way

To install ASDF, follow the manuals and steps bellow...

$ git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.4.3

# Add the two lines bellow on your terminal load file (e. .bashrc, .zshrc)
. $HOME/.asdf/asdf.sh
. $HOME/.asdf/completions/asdf.bash

# Adding plugins for ruby and nodejs
$ asdf plugin-add ruby https://github.com/asdf-vm/asdf-ruby.git
$ asdf plugin-add nodejs https://github.com/asdf-vm/asdf-nodejs.git

* I do not recommend you migrate ruby version from RVM, because is fast to install ruby versions.

# To install the tools ruby and nodejs, follow bellow steps

# Ruby

$ asdf install ruby 2.2.9

# Set ruby version locally - asdf <global | local> ruby <version>
$ asdf local ruby 2.2.9

$ ruby --version # ruby 2.2.9p480 (2017-12-15 revision 61259) [x86_64-darwin17]

# Nodejs

# (slow)Imports NodeJS release team's OpenPGP keys to main keyring
$ brew install gpg

** For debian, executes:

    $ sudo apt-get install gpg dirmngr

$ bash ~/.asdf/plugins/nodejs/bin/import-release-team-keyring
$ asdf install nodejs 8.10.0

** When install or update a new version and receive the error: No public key. Executes:

$ bash ~/.asdf/plugins/nodejs/bin/import-release-team-keyring

If does not work, try:

$ gpg --keyserver pool.sks-keyservers.net --recv-keys <key-that-has-error>


# Common commands

# Set a local tool version
$ asdf local <name> <version>

# List details of tools
$ asdf current

# Set a tool version
$ asdf local <name> <version>

# List the versions of a tool
$ asdf list <name>

# Detail of environment

When you set a version GLOBAL, this is set in ~/.tool-versions
Otherwise, if you set LOCAL, a file called .tool-versions will be saved in that folder.
I prefer always to use LOCAL.
