Duplicate plugin/preset detected
Closed this issue · 2 comments
Hi.
I've installed the 'professional-ts' project, followed all instructions about how install it, but when I'm trying to run command "yarn dev" I've got a big fat error in my console.
/Users/Dima/PROJECTS /THEORY/Front-End Masters/TS Production-Grade/professional-ts/src/index.js: Duplicate plugin/preset detected. If you'd like to use two separate instances of a plugin, they need separate names, e.g.
plugins: [ ['some-plugin', {}], ['some-plugin', {}, 'some unique name'], ]
Duplicates detected are: [ { "alias": "/Users/Dima/PROJECTS /THEORY/Front-End Masters/TS Production-Grade/professional-ts/node_modules/@babel/plugin-proposal-class-properties/lib/index.js", "dirname": "/Users/Dima/PROJECTS /THEORY/Front-End Masters/TS Production-Grade/professional-ts", "ownPass": false, "file": { "request": "@babel/plugin-proposal-class-properties", "resolved": "/Users/Dima/PROJECTS /THEORY/Front-End Masters/TS Production-Grade/professional-ts/node_modules/@babel/plugin-proposal-class-properties/lib/index.js" } }, { "alias": "base$1", "options": { "loose": "#__internal__@babel/preset-env__prefer-false-but-true-is-ok-if-it-prevents-an-error" }, "dirname": "/Users/Dima/PROJECTS /THEORY/Front-End Masters/TS Production-Grade/professional-ts", "ownPass": false } ]
Check if removing @babel/plugin-proposal-class-properties from .babelrc will fix it for you.
