今日、プロジェクトを书く过程で问题が発生しました---パスワードを暗号化して、bcryptをインストールする必要がありますが、いつも多くの间违いを报告して、インストールはとても难しいです~~~

参考までに以下の方法をまとめました

シナリオ1:

cmd入力コマンドを開く:npm install-g node-gyp車に戻ったらnpm install--global--production windows-build-toolsを入力してからnpm install bcrypt-S
シナリオ1が間違っている場合は、シナリオ2を使ってみましょう.bcryptjsを引用すると、望ましい効果が得られ、間違っていません~~

シナリオ2:

npm install bcryptjs -S
let bcrypt=require(‘bcryptjs’)
すぐに問題を解決しました.ハハハ.
