webpack4 less编译 Cannot read property 'lessLoader'

Question

直接贴错误信息吧

ERROR in ./app/index.less (./node_modules/_css-loader@0.23.1@css-loader!./node_modules/_less-loader@2.2.3@less-loader!./app/index.less)

Module build failed: TypeError: Cannot read property 'lessLoader' of undefined

    at Object.module.exports (E:\第一类永动机关\web前端\Project\Study\react-music\node_modules\_less-loader@2.2.3@less-loader\index.js:50:18)

 @ ./app/index.less 4:14-150

 @ ./app/index.js

从错误信息里看..是直接从less-loader里报出来的不存在没装的情况

less-loader能运行，也不存在less没装的情况

我试了下css可以解析，也不是style-loader,和css-loader的问题。

去翻reademe看到的列子是webpack2还是1的写法，没有意义...

附上我得写法..至少我一眼看上去是没错...求解？

          {

            test: /\.less/,

            use: [

              { loader: 'style-loader' },

              { loader: 'css-loader' },

              { loader: 'less-loader' }

            ]

          }

Answer 1

The less-loader requires less as peerDependency. Thus you are able to control the versions accurately.
