Nodeバージョン管理ツール「n」でバージョンが切り替わらない

Posted at

困った内容

n コマンドを使ってもバージョンが変わっていない

  • コマンド
コマンド
sudo npm install -g n
n -V
n --stable
sudo n stable
node -v
  • 実行例
実行例
$ sudo npm install -g n
...省略
$ n -V
v9.0.1
$ n --stable
18.12.1
$ sudo n stable
     copying : node/18.12.1
   installed : v18.12.1 (with npm 8.19.2)
$ node -v
v12.22.12 // 変わってない

原因

which node~/.bash_profile の記載が異なる

  • コマンド
コマンド
which node
cat ~/.bash_profile
  • 実行例
実行例
$ which node
/usr/local/bin/node
$ cat ~/.bash_profile
PATH="$HOME/bin:$HOME/.local/bin:$PATH"

対処法

~/.bash_profile の記載を変更する

  • コマンド
コマンド
echo 'export PATH=$HOME/bin:$PATH' >> ~/.bash_profile
source ~/.bash_profile
node -v
  • 実行例
実行例
$ echo 'export PATH=$HOME/bin:$PATH' >> ~/.bash_profile
