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/
