我似乎无法再测试我的文件了。

我“npm i react react-dom react-addon-test-utils”

我什至尝试安装两个 devdep。和部门。

我从 here 找到了解决此问题的方法

make sure that your app contains follow dependencies all in the sameversion in package.json

react-addons-test-utils

react

react-dom

"react": "^0.14.7",
"react-addons-test-utils": "^0.14.7",
"react-dom": "^0.14.7",

或者升级到上述依赖的最新版本
