=> Appending bash_completion source string to /home/tomoyan/.bashrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
実行後は **~/.bashrc** に **nvm** の設定が追加されるので、端末を再起動するか **~/.bashrc** を手動で実行する。\\
$ cat ~/.bashrc
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# User specific environment
PATH="$HOME/.local/bin:$HOME/bin:$PATH"
export PATH
# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=
# User specific aliases and functions
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
**~/.bashrc** を手動で実行する。\\
$ . ~/.bashrc
**nvm** の動作確認。\\
$ nvm --version

※Linux の **nvm** では、バージョン確認は **--version** オプションである。\\

Node Version Manager (v0.35.3)
Note: refers to any version-like string nvm understands. This includes:
- full or partial version numbers, starting with an optional "v" (0.10, v0.1.2, v1)
- default (built-in) aliases: node, stable, unstable, iojs, system
- custom aliases you define with `nvm alias foo`
Any options that produce colorized output should respect the `--no-colors` option.
