Node-gyp にて大量のエラーメッセージ

前提・実現したいこと

それは node-opus をインストールしようとした時です。
コマンドラインが一気に埋め尽くされていくではありませんか！
何をすれば（どうすれば）問題なくインストールすることが出来るか、
お教えください。

・Visual Studio Build Tools も 2019年版にした (msvs_version も一緒に)
・パスの空白をなくした
・node-gyp の GitHub の Issue を見てパスに日本語が入っていても大丈夫な設定にした
・PC を変えた

補足情報（FW/ツールのバージョンなど）

OS: Windows_NT 10.0.18362
VS: VS2019 (16.1.29102.190)
Node: node v12.6.0
Node-gyp: node-gyp@5.0.3

node-gyp configure got “gyp ERR! find VS” - Stack Overflow

エラーメッセージを見ると
"gyp ERR! find VS including the "Desktop development with C++" workload."
という文言がありますね。

Visual Studioに加えて、C++の開発ツールのインストールが必要です。
手順は以下のとおりです。
（node.js、npm、node-gyp、Visual Studio、Visual Studio Installerは必要に応じて最新にしてください。）

Visual Studioを起動
「ツール > ツールと機能を取得」と選択し、Visual Studio Installerを起動

「C++によるデスクトップ開発」に☑をつけて「変更」

インストールが始まります。しばらく待ち、インストールに成功していたら再度
node-gyp rebuild
を実行してみてください。

windows-build-toolsはインストールしましたか？

node-gypはあくまでビルドを管理するツールですので、実際のコンパイラが別途で必要です。

どうやら "windows-build-tools" が "Visual Studio Build Tools" の様です。インストールしたら : "VS2013" は "Node.js 8" じゃないと対応しない最新版をインストールしてくれとのことでした... ただひとつ、疑問に思いました。 Visual Studio Installer を見ると、ちゃんと VS2017 がインストールされていました... - 発生している問題・エラーメッセージ - gyp info it worked if it ends with ok gyp info using node-gyp@5.0.3 gyp info using node@12.6.0 | win32 | x64 gyp info find Python using Python version 2.7.16 found at "C:\Python27\python.exe" gyp ERR! find VS gyp ERR! find VS msvs_version not set from command line or npm config gyp ERR! find VS VCINSTALLDIR not set, not running in VS Command Prompt gyp ERR! find VS could not use PowerShell to find Visual Studio 2017 or newer gyp ERR! find VS looking for Visual Studio 2015 gyp ERR! find VS - not found gyp ERR! find VS not looking for VS2013 as it is only supported up to Node.js 8 gyp ERR! find VS gyp ERR! find VS ************************************************************** gyp ERR! find VS You need to install the latest version of Visual Studio gyp ERR! find VS including the "Desktop development with C++" workload. gyp ERR! find VS For more information consult the documentation at: gyp ERR! find VS https://github.com/nodejs/node-gyp#on-windows gyp ERR! find VS ************************************************************** gyp ERR! find VS gyp ERR! configure error gyp ERR! stack Error: Could not find any Visual Studio installation to use gyp ERR! stack at VisualStudioFinder.fail (C:\Users\裕斗\AppData\Roaming\npm\node_modules\node-gyp\lib\find-visualstudio.js:121:47) gyp ERR! stack at C:\Users\裕斗\AppData\Roaming\npm\node_modules\node-gyp\lib\find-visualstudio.js:74:16 gyp ERR! stack at VisualStudioFinder.findVisualStudio2013 (C:\Users\裕斗\AppData\Roaming\npm\node_modules\node-gyp\lib\find-visualstudio.js:344:14) gyp ERR! stack at C:\Users\裕斗\AppData\Roaming\npm\node_modules\node-gyp\lib\find-visualstudio.js:70:14 gyp ERR! stack at C:\Users\裕斗\AppData\Roaming\npm\node_modules\node-gyp\lib\find-visualstudio.js:365:16 gyp ERR! stack at C:\Users\裕斗\AppData\Roaming\npm\node_modules\node-gyp\lib\util.js:54:7 gyp ERR! stack at C:\Users\裕斗\AppData\Roaming\npm\node_modules\node-gyp\lib\util.js:33:16 gyp ERR! stack at ChildProcess.exithandler (child_process.js:304:5) gyp ERR! stack at ChildProcess.emit (events.js:203:13) gyp ERR! stack at maybeClose (internal/child_process.js:1021:16) gyp ERR!
