An error is reported when using webpack-dev-server to build a development server, and the error message is as follows:[webpack-cli] TypeError: cli.isMultipleCompiler is not a function.
This problem occurs when the less writing style is used in Vue. The reason for this problem is that the less-loader module is not installed, or the installed version is incompatible with the version of webpack. Therefore, an error occurs when using it, and the project cannot be started normally.
