答
对于Babel版本6，软件包名称为 babel-preset-es2015 ，对于Babel版本7，软件包名称为 @babel/preset-es2015 .
For Babel version 6 the package name is babel-preset-es2015 and for Babel version 7 the package name is @babel/preset-es2015.
从该错误看来，您正在使用版本7.已弃用 es20XX-presets ，因此，我建议您切换到
From the error it seems that you're using version 7. The es20XX-presets are deprecated, so I recommend you switch to @babel/preset-env.
首先安装预设(使用 npm ):
First install the preset (using npm):
npm install --save-dev @babel/preset-env
然后将预设添加到您的 .babelrc
Then add the preset to your .babelrc
{
presets: ["@babel/preset-env"]
}
