regeneratorRuntime 未定义 rete.js

Question

好吧，我可以找到解决问题的方法。我正在尝试将 Rete.js in Next.js 与 Typescript 一起使用。我看到以下错误：

regeneratorRuntime is not defined

这是我的配置

package.json

"dependencies": {
    "@types/next": "^9.0.0",
    "@types/react": "^16.9.19",
    "next": "^9.2.1",
    "react": "^16.12.0",
    "react-dom": "^16.12.0",
    "rete": "^1.4.3-rc.1",
    "rete-area-plugin": "^0.2.1",
    "rete-connection-plugin": "^0.9.0",
    "rete-dock-plugin": "^0.2.1",
    "rete-react-render-plugin": "^0.2.0"
  },
"devDependencies": {
    "@babel/plugin-transform-runtime": "^7.8.3",
    "@types/node": "^13.7.1",
    "typescript": "^3.7.5"
  }
}

tsconfig.json

{
  "compilerOptions": {
    "allowJs": true,
    "allowSyntheticDefaultImports": true,
    "jsx": "preserve",
    "lib": [
      "dom",
      "es2017"
    ],
    "module": "esnext",
    "moduleResolution": "node",
    "noEmit": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "preserveConstEnums": true,
    "removeComments": false,
    "skipLibCheck": true,
    "sourceMap": true,
    "strict": true,
    "target": "esnext",
    "forceConsistentCasingInFileNames": true,
    "esModuleInterop": true,
    "resolveJsonModule": true,
    "isolatedModules": true
  },
  "exclude": [
    "node_modules"
  ],
  "include": [
    "next-env.d.ts",
    "**/*.ts",
    "**/*.tsx"
  ]
}

.babelrc

{
    "presets": ["next/babel"],
    "plugins": [
        [
          "@babel/plugin-transform-runtime",
          {
            "absoluteRuntime": false,
            "corejs": false,
            "helpers": true,
            "regenerator": true,
            "useESModules": false,
            "version": "7.0.0-beta.0"
          }
        ]
    ]
 }

我也试过安装 core-js 和 regenerator-runtime 并试过：

import "core-js/stable";
import "regenerator-runtime/runtime";

但对我来说没有任何效果。你能提出一些可以解决我的问题的建议吗？

Answer 1

不需要安装core-js和regenerator-runtime。 @babel/plugin-transform-runtime 正在提供所需的运行时。我只是遗漏了一个基本的东西，没有添加 @babel/preset-env。我假设 next/babel 包含 .babelrc 文件所需的所有内容，但事实并非如此。这是对我有用的最终 .babelrc 文件。

{
    "presets": [
        "@babel/preset-env",
        "next/babel"
      ],
      "plugins": [
        ["@babel/plugin-transform-runtime"]
      ]     
}
