@lsby

Fixed: dca816e3dcd894a845c7ebe260d726c3ae22379a

@rollup/plugin-url 4.0.2 版本的 peerDependency 对 rollup 有版本限制，与根目录的 rollup 版本冲突了。看了下目前项目中 @rollup/plugin-url 并没有起到作用，所以删除了 @rollup/plugin-url 依赖

@SmallStoneSK 然鹅在最新版本的提交(dca816e3dcd894a845c7ebe260d726c3ae22379a)上执行npm i 依然还有其他的对等依赖报错:

即使把rollup-plugin-size-snapshot改为^0.12.0 还会有关于umi的对等依赖冲突qwq

@lsby 看报错信息好像都是 peer-deps 的问题

npm install --legacy-peer-deps 

试一下呢？
