aws cdk 2.0 init 应用程序无法构建更漂亮的问题，这是来自 jest-snapshot

Question

节点：v16.7.0
cdk：2.0.0（构建 4b6ce31）

package.json:

  "devDependencies": {
    "@types/jest": "^26.0.10",
    "@types/node": "10.17.27",

npm 运行 build/watch 堆栈跟踪：

我注意到 prettier 来自 jest-snapshot in package-lock.json:

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

      "dependencies": {

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

有什么想法吗？

我时不时地遇到这个问题，看起来这就是问题所在 https://github.com/aws/aws-cdk/issues/20319

将固定版本的 prettier 添加到 Dev 依赖项的建议解决方案对我有用。试一试

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

如果您使用 projen 进行脚手架，更改应该在 projen.js 文件中

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