prisma generate throws TypeError: collection is not iterable

Question

我正在使用带有 prisma 的打字稿，当我尝试运行 prisma generate 时，它一直在抛出

TypeError: collection is not iterable.
 at keyBy (/node_modules/@prisma/client/generator-build/index.js:57685:21)
    at Object.getTypeMap (/node_modules/@prisma/client/generator-build/index.js:59468:17)

    at async LineStream.<anonymous> (/node_modules/@prisma/client/generator-build/index.js:54186:24)

我认为设置有问题，但找不到具体原因。

我的prisma版本是3.9.2，@prisma/client是3.10.0，用的是macos

tsconfig.json

    /* Type Checking */
    "strict": true,
    "skipLibCheck": true
  },
  "include": ["src/**/*"],
  "exclude": ["node_modules"]
}

package.json

{
  "scripts": {
    "dev": "nodemon --watch \"src/**/*.ts\" --exec \"ts-node\" src/app.ts",
    "build": "tsc -p tsconfig.json",

    "prettier": "^2.5.1",

    "typescript": "^4.5.5"
  }
}

解决了！

我刚刚在 devdependency 中重新安装了 Prisma，它工作正常。

您需要将这两个包升级到最新版本

yarn add prisma@latest / npm i prisma@latest
yarn add @prisma/client@latest / npm i @prisma/client@latest
