而不是

//# sourceMappingURL=../.sourcemap/mp-weixin/common/main.js.map

复现步骤
[复现问题的步骤]

vue create -p dcloudio/uni-preset-vue my-project  // 正式版vuecli 创建项目即可复现

补充信息
应该是webpack5 不太一样

if (filename) {
      options.append = "\n//# sourceMappingURL=../[url]" //  it work!
      options.filename = '../.sourcemap/' + process.env.UNI_PLATFORM + '/[file].map'
    }

额...没有进展吗，还是只有我有这个问题😂

求解决，我也是这个问题

写个webpack插件替换source map路径

const webpack = require('webpack')
class ReplaceSourceMappingURL {
  apply(compiler) {
    const regexp = /\/\/\# sourceMappingURL=(.*).js.map/;
    const replaceStr = '//# sourceMappingURL=../$1.js.map';
    compiler.hooks.thisCompilation.tap('ReplaceSourceMappingURL', (compilation) => {
      compilation.hooks.processAssets.tap(
        {
          name: 'ReplaceSourceMappingURL',
          stage: webpack.Compilation.PROCESS_ASSETS_STAGE_SUMMARIZE // see below for more stages
        },
        (assets) => {
          for (const filename in assets) {
            if (filename.endsWith('.js')) {
              const source = assets[filename].source().replace(regexp, replaceStr);
              assets[filename] = new webpack.sources.RawSource(source);
            }
          }
        }
      );
    });
  }
}

module.exports = {
  configureWebpack: {
    plugins: [new ReplaceSourceMappingURL()]
  }
};
