如何从每个包中提取公共devDependencies到根package.json文件？

Question

我已经使用lerna import <PATH_OF_PROJECT>命令将两个现有项目导入monorepo。

每个项目都有一个package.json文件，它们有一些常见的devDependencies

packages/redux-saga-examples/package.json

"devDependencies": {
  "@testing-library/react": "^12.0.0",
  "@types/jest": "^26.0.24",
  "@types/redux-actions": "^2.6.2",
  "jest": "^27.0.6",
  "ts-jest": "^27.0.4",
  "ts-node": "^9.1.1",
  "typescript": "^4.3.5"
}

packages/redux-toolkit-example/package.json

"devDependencies": {
  "@redux-saga/testing-utils": "^1.1.3",
  "@types/jest": "^26.0.23",
  "@types/redux-mock-store": "^1.0.2",
  "jest": "^27.0.4",
  "prettier": "^2.3.1",
  "redux-mock-store": "^1.5.4",
  "redux-saga-test-plan": "^4.0.1",
  "ts-jest": "^27.0.3",
  "ts-node": "^10.0.0",
  "typescript": "^4.3.4"
}

redux-examples/package.json

{
  "name": "root",
  "private": true,
  "scripts": {
    "bootstrap": "lerna bootstrap --hoist",
    "test": "jest"
  },
  "devDependencies": {
    "lerna": "^4.0.0"
  }
}

现在，我希望将常见的devDependencies (如typescript、jest、@types/jest )提取到monorepo根package.json的devDependencies中。我试过了lerna bootstrap --hoist，devDependencies还在每个包里。

是否有lerna提供的任何命令来执行此操作？期望根的package.json：

{
  "name": "root",
  "private": true,
  "scripts": {
    "bootstrap": "lerna bootstrap --hoist",
    "test": "jest"
  },
  "devDependencies": {
    "@types/jest": "^26.0.24",
    "lerna": "^4.0.0",
    "jest": "^27.0.6",
    "ts-jest": "^27.0.4",
    "ts-node": "^9.1.1",
    "typescript": "^4.3.5"
  }
}

和每个包的package.json文件：

packages/redux-saga-examples/package.json

"devDependencies": {
  "@testing-library/react": "^12.0.0",
  "@types/redux-actions": "^2.6.2"
}

packages/redux-toolkit-example/package.json

"devDependencies": {
  "@redux-saga/testing-utils": "^1.1.3",
  "@types/redux-mock-store": "^1.0.2",
  "prettier": "^2.3.1",
  "redux-mock-store": "^1.5.4",
  "redux-saga-test-plan": "^4.0.1"
}

我不认为这仍然是一个悬而未决的问题，但是您可以使用lerna提供的命令

lerna link connect

此命令将从所有包中分离dev依赖项，并将其放在根上。
