To install multiple versions of the same package, we need to use the package alias syntax which is supported from the npm v6.9.0.
Example:
npm install react15@npm:react@15npm install react16@npm:react@16
This above command installs the react library v15, v16 by aliasing react15 and react16.
The package.json file looks like this.
"dependencies": { "react15": "npm:react@^15.6.2", "react16": "npm:react@^16.13.1" }
