For Babel version 6 the package name is babel-preset-es2015 and for Babel version 7 the package name is @babel/preset-es2015.
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.
First install the preset (using npm):
npm install --save-dev @babel/preset-env
Then add the preset to your .babelrc
{
"presets": ["@babel/preset-env"]
}
Thing in that the babel 7 uses @babel/preset-env. Other presets are deprecated
Here saying about this https://babeljs.io/docs/en/v7-migration#yearly-preset-deprecations-blog-2017-12-27-nearing-the-70-releasehtml-deprecated-yearly-presets-eg-babel-preset-es20xx
You should specify in a configuration file (I don't know if you are using Webpack or something else) preset as "@babel/preset-env". Install it through npm install --save-dev @babel/preset-env
For example, you are using Webpack module bundler. In that case, specify like this:
use: {
loader: "babel-loader",
options: {
presets: ["@babel/preset-env"]
}
}
Here is a documentation https://webpack.js.org/loaders/babel-loader/ if you suddenly will need.
Happy coding!
