+#nodenv導入
+github:https://github.com/nodenv/nodenv
+
+1. nodenvをクローンする
+
+```
+git clone https://github.com/nodenv/nodenv.git ~/.nodenv
+```
+
+インストール時間を短縮するためダイナミックバッシュでコンパイルする（失敗してもインストールできる）
+
+```
+cd ~/.nodenv && src/configure && make -C src
+```
+
+2. nodenvを`PATH`に追加する
+
+```
+echo 'export PATH="$HOME/.nodenv/bin:$PATH"' >> ~/.bashrc
+```
+
+現在のシェルにbash適用する
+
+```
+source ~/.bashrc
+```
+
+3. nodenvをshellにセットアップする
+
+```
+~/.nodenv/bin/nodenv init
+```
+
+表示されたコマンドで実行する
+**プラットフォームによってコマンド違うので下記のコマンドを実行しない**
+
+```
+echo 'eval "$(nodenv init - bash)"' >> ~/.bashrc
+source ~/.bashrc
+```
+
+4. nodenvインストール確認
+
+```
+curl -fsSL https://github.com/nodenv/nodenv-installer/raw/main/bin/nodenv-doctor | bash
+```
+
+下記の画面表示されたら完了
+

+Checking for `nodenv' in PATH: /home/nik/.nodenv/bin/nodenv
+Checking for nodenv shims in PATH: OK
+Checking `nodenv install' support: not found
+Unless you plan to add Node versions manually, you should install node-build.
+Please refer to https://github.com/nodenv/node-build#installation
+
+Counting installed Node versions: none
+  There aren't any Node versions installed under `/home/nik/.nodenv/versions'.
+  You can install Node versions like so: nodenv install <version>
+Auditing installed plugins: OK

+git clone https://github.com/nodenv/node-build.git "$(nodenv root)"/plugins/node-build

+.bashrcにaliasにしたいコマンド書く

+
+例：

+この場合は`export AWS_PROFILE=medaca`コマンドが`medaca`に省略できる
