    问题

    The react-scripts package provided by Create React App requires a dependency:

      "babel-jest": "23.6.0"

    Don't try to install it manually: your package manager does it automatically.

    However, a different version of babel-jest was detected higher up in the tree:

      /home/karan/workspace/node_modules/babel-jest (version: 22.4.4)

    解决方法

    1. 删除yarn.lock和node-modules

    2. 修改package.json,添加

    "resolutions": {

        "jest": "23.6.0",

        "babel-jest": "23.6.0"

    },

    3. npm install

    4. npm start

    可参考 https://yarnpkg.com/lang/en/docs/selective-version-resolutions/
