Requires Babel \"^7.0.0-0\", but was loaded with \"6.26.3\"
解决方法：
每个人遇到该问题的根源可能不一样，我遇到的问题的解决方式是：
--------------------------------------------------------------------------------------------
npm install --save-dev @babel/core @babel/cli
--------------------------------------------------------------------------------------------
后来在结合webpack的过程中又出现了这个类似问题，这次使用的命令是：
--------------------------------------------
npm install --save-dev babel-core babel-loader@8 babel-plugin-transform-runtime
--------------------------------------------
第一次实际上是因为cli报出的这个错，第二次是因为babel-loader报出的这个错，报的是不一样的，所以解决方式也不一样。
原因分析：
报错中的“node_modules\babel-cli\”说明调用的是babel6的命令，而实际上7.0应该是这样的文件夹“node_modules\@babel\cli”， babel7是以@开头的。

Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version. Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel.
