so when I install these packages locally they work, but when installed globally (and removed them locally)
npm i babel-cli -g
npm i -g babel-preset-es2015
npm i -g babel-preset-es2015-node
seems like that flag isn't setting es2016-node to look in the global package list. anyways this following error occurs:
npm run start myfile.js
babel-node --presets es2015-node -- bin/myScript.js "myfile.js"

throw new Error("Couldn't find preset " + (0, _stringify2.default)(val) + " relative to directory " + (0, _stringify2.default)(dirname));
^

A hint is in the error message:
Couldn't find preset "es2015-node" relative to directory "/Users/user/project/bin"
Install the presets locally and have them saved as dependencies in your package.json
by using the --save
flag:
npm install --save babel-preset-es2015-node babel-preset-es2015
It is a wise move by Babel that presets are looked for locally only. This way you are forced to produce a module that is portable by describing the necessary dependencies required for its operation within the package.json
, which are then installed by users via npm install
.
