=> Appending nvm source string to /home/tomoyan/.bashrc
=> 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 ~/.bashrcnvm 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。

$ nvm --help
Node Version Manager (v0.35.3)
 
Note: <version> 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.
