aws cdk 2.0 init 應用程序無法構建更漂亮的問題，這來自 jest-snapshot

Question

節點：v16.7.0
cdk：2.0.0（構建 4b6ce31）

package.json：

  "devDependencies": {
    "@types/jest": "^26.0.10",
    "@types/node": "10.17.27",
    "aws-cdk": "2.0.0",
    "jest": "^26.4.2",
    "ts-jest": "^26.2.0",
    "ts-node": "^9.0.0",
    "typescript": "^3.9.7"
  },
  "dependencies": {
    "aws-cdk-lib": "2.0.0",
    "constructs": "^10.0.0",
    "source-map-support": "^0.5.16"
  }

npm 運行構建/觀察堆棧跟蹤：

我注意到更漂亮的來自package-lock.json中的jest-snapshot ：

    "node_modules/jest-snapshot": {
      "version": "26.6.2",
      "resolved": "https://registry.npmjs.org/jest-snapshot/-/jest-snapshot-26.6.2.tgz",

      "dev": true,
      "dependencies": {

        "@jest/types": "^26.6.2",
        "@types/babel__traverse": "^7.0.4",
        "@types/prettier": "^2.0.0",

      },
      "engines": {
        "node": ">= 10.14.2"
      }
    },

有任何想法嗎？

Answer 1

我時時刻刻都面臨着這個問題，看起來這就是問題https://github.com/aws/aws-cdk/issues/20319

向 Dev 依賴項添加一個更漂亮的固定版本的建議解決方案對我有用。 試試看

{
  "devDependencies": {
    "@types/prettier": "2.6.0"
  }
}

如果您使用 projen 進行腳手架，則更改應該在 projen.js 文件中

devDeps: [
    '@types/prettier@2.6.0'
]

Answer 2

我必須安裝 npm 才能讓它工作：

  npm install @types/prettier@2.6.0
