is a version problem. The solution is to lower the less-loader version. My vue version is 2.5.2.

Uninstall the latest version first

yarn remove less-loader
npm uninstall less-loader123

Install the less-loader 5.0.0 version

yarn add less-loader@5.0.0
npm install less-loader@5.0.0 -D123

Error when running npm install:

Console input npm -V found that my npm version is 7.x, because npm7.x The version is stricter on some commands than npm6.

2) Using npm6.x

Tips: There is no need to uninstall npm@7 when using npm@6. You can use npx to specify the version of npm. For example: npx -p npm@6 npm i --legacy-peer-deps

If this doesn't work immediately, you can delete node_modules and package-lock.json
