补充信息

ctx.modifyBuildAssets(({ assets, miniPlugin }) => { const pages = []; 下面加上 if (typeof miniPlugin === 'undefined') { return } 可以编译通过。

因为taro-webpack-runner/src/index.ts

compiler.hooks.emit.tapAsync('taroBuildDone', async (compilation, callback) => { if (typeof config.modifyBuildAssets === 'function') { // 此处并未传入miniPlugin，因此可能导致报错 await config.modifyBuildAssets(compilation.assets) } callback() })
