解決方法

Warning: Unbrewed header files were found in /usr/local/include.

まずは以下のWarningを解決した方法を書きます。

ターミナル
Warning: Unbrewed header files were found in /usr/local/include.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected header files:
  /usr/local/include/node/js_native_api.h
  /usr/local/include/node/js_native_api_types.h
  /usr/local/include/node/libplatform/libplatform-export.h
  /usr/local/include/node/libplatform/libplatform.h
  .
  .
  .
  .
  /usr/local/include/node/v8.h
  /usr/local/include/node/v8config.h
  /usr/local/include/node/zconf.h
  /usr/local/include/node/zlib.h

このWarningに書いてあることは、
/usr/local/includeというファイルあるけど、意図的においている訳ではないなら削除して
みたいな感じなので書かれた通りにファイルを削除していきます。

ターミナルに以下を入力して、vimでファイル作成、vimのテキストエディタを開きます。

ターミナル
$ vim ~/.del_files.sh

vimのテキストエディタが開けたらiを入力してINSERTモードに変更します。
1行目に#!/bin/bashを入力し、2行目以降にUnexpected dylibs:以下にあるファイルをコピペして、escを押して、ノーマルモードに変更します。

vim
#!/bin/bash
  /usr/local/include/node/js_native_api.h
  /usr/local/include/node/js_native_api_types.h
  /usr/local/include/node/libplatform/libplatform-export.h
  /usr/local/include/node/libplatform/libplatform.h
  .
  .
  .
  .
  /usr/local/include/node/v8.h
  /usr/local/include/node/v8config.h
  /usr/local/include/node/zconf.h
  /usr/local/include/node/zlib.h

カーソルを#!/bin/bashの下にあるファイルの先頭に置いて、control + vでビジュアルモード(VISUAL BLOCK)に変更し、一番下のファイルまで移動して:を押します。
そうすると下に:'<,'>が入力された状態でコマンドラインが表示されるので、続けてs/^/rm -f /と入力します。

Enterを押して、全てのファイルの先頭にrm -fと追加されているのを確認したら、:を押して、一番下の入力欄にwq!と入力してEnterを押します。

vim
#!/bin/bash
rm -f   /usr/local/include/node/js_native_api.h
rm -f   /usr/local/include/node/js_native_api_types.h
rm -f   /usr/local/include/node/libplatform/libplatform-export.h
rm -f   /usr/local/include/node/libplatform/libplatform.h
.
.
.
.
rm -f   /usr/local/include/node/v8.h
rm -f   /usr/local/include/node/v8config.h
rm -f   /usr/local/include/node/zconf.h
rm -f   /usr/local/include/node/zlib.h

そうすると通常のターミナルに戻るので、

ターミナル
$ bash ~/.del_files.sh

を実行するとファイルが削除できるはずだったのですが、

ターミナル
$ bash ~/.del_files.sh
rm: /usr/local/include/node/js_native_api.h : Permission denied
rm: /usr/local/include/node/js_native_api_types.h: Permission denied
rm: /usr/local/include/node/libplatform/libplatform-export.h: Permission denied
rm: /usr/local/include/node/libplatform/libplatform.h: Permission denied
  .
  .
  .
  .
rm: /usr/local/include/node/v8.h: Permission denied
rm: /usr/local/include/node/v8config.h: Permission denied
rm: /usr/local/include/node/zconf.h: Permission denied
rm: /usr/local/include/node/zlib.h: Permission denied

のように表示されて削除ができませんでした。

ファイルの後ろに: Permission deniedと書かれているので、権限を付与するかsudoコマンドで実行することが必要と判断して、sudoコマンドの実行をするためにもう一度vim ~/.del_files.shを開いてsudoコマンドを追加します。

まず、vim ~/.del_files.shをターミナルに入力してvimのテキストエディタを開きます。

その後、ファイルの先頭にカーソルを合わせて、control + vでビジュアルモード(VISUAL BLOCK)に変更して、一番下のファイルまで移動して、:を押します。

先ほどと同様に下に:'<,'>が表示されるので、今度はs/^/sudo /と入力して、Enterを押します。

ファイルの先頭にsudoと追加できていたら:を押して、コマンドラインにwq!と入力してEnterを押します。

vim
#!/bin/bash
sudo rm -f   /usr/local/include/node/js_native_api.h
sudo rm -f   /usr/local/include/node/js_native_api_types.h
sudo rm -f   /usr/local/include/node/libplatform/libplatform-export.h
sudo rm -f   /usr/local/include/node/libplatform/libplatform.h
.
.
.
.
sudo rm -f   /usr/local/include/node/v8.h
sudo rm -f   /usr/local/include/node/v8config.h
sudo rm -f   /usr/local/include/node/zconf.h
sudo rm -f   /usr/local/include/node/zlib.h

通常のターミナルに戻ってきたら以下のコマンドを実行します。

ターミナル
$ bash ~/.del_files.sh

これでWarningの一つが解決しました。

Warning: You have unlinked kegs in your Cellar.

次にこのWarningを解決した方法を書きます。

ターミナル
Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  node

とりあえず読んでみるとbrew linkしてくださいということが書かれているみたいですが、今回は一度消してからnodeをインストールしたいと思っているので、リンク先のディレクトリを削除していきます。

ターミナル
$ brew unlink node
Unlinking /usr/local/Cellar/node/14.5.0... 0 symlinks removed

次に表示されているディレクトリを削除します。

ターミナル
$ rm -drf /usr/local/Cellar/node/

Warningを解決したのでbrew doctorで確認します。

ターミナル
$ brew doctor
