wepy 这个demo项目一直报错

[txw8]

安装项目依赖后 运行 wepy build --watch命令 报错 提示安装 @wepy/compiler-babel 和@wepy/compiler-less, 安装好这两个依赖后 又提示The 'decorators' plugin requires a 'decoratorsBeforeExport' option, whose value must be a boolean. If you are migrating from Babylon/Babel 6 or want to use the old decorators proposal, you should use the 'decorators-legacy' plugin instead of 'decorators'. 请问该如何配置呢?
