はじめに

前回、構築したVue3+TypeScriptの環境ににtailwindcssをインストールした

結論

下記のエラーが発生してエラーを解消できなくなってしまった。

 INFO  Starting development server...

結果

下記のサイトでvue3+tailwindcss+typescriptの環境構築できるサンプルがあったので、こちらをベースに勉強しようかと思いました。 github.com

エラーの原因かと思うポイント1

自分と異なる点はpostcssのバージョンだと思った。成功しているpackege.jsonのpostcss7になっている。

{
  "name": "vue3-tailwind2",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build"
  },
  "dependencies": {
    "autoprefixer": "^9.8.6",
    "core-js": "^3.6.5",
    "postcss": "^7.0.35",
    "tailwindcss": "npm:@tailwindcss/postcss7-compat@^2.0.1",
    "vue": "^3.0.0",
    "vue-router": "^4.0.0-0",
    "vuex": "^4.0.0-0"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-router": "~4.5.0",
    "@vue/cli-plugin-typescript": "~4.5.0",
    "@vue/cli-plugin-vuex": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "@vue/compiler-sfc": "^3.0.0",
    "node-sass": "^4.12.0",
    "sass-loader": "^8.0.2",
    "typescript": "~3.9.3"
  }
}

自分の環境のpackege.jsonは下記のようになっている。
