babel运行时缺少interop-require-default

Question

不知道如何解决此错误。 做了一些谷歌搜索，并遵循人们的建议。 甚至删除了node_modules并重新安装，但没有任何效果

我收到此错误：

 Error: Cannot find module 'babel-runtime/helpers/interop-require-default' (While processing preset: "/Users/bli1/Development/node_modules/babel-preset-es2015/index.js")

package.json：

在package.json中缺少插件babel-preset-es2015 ，在执行npm install时未npm install 。 添加它，然后重新安装。
