What happens?

prerender-spa-plugin-next 是一个生成支持seo静态页面的插件。

cra创建的项目中，webpack配置如下，可以正常工作

// const PrerenderSPAPlugin = require('prerender-spa-plugin');
const path = require('path')
const PrerenderSPAPlugin = require("prerender-spa-plugin-next");

const renderer = require('@prerenderer/renderer-puppeteer')

module.exports = (config, env) => {
  if (env === 'production') {
    config.plugins = config.plugins.concat([
      new PrerenderSPAPlugin({
        routes: ['/'],
        renderer,
        rendererOptions: {
          // 引用地址
          executablePath: path.resolve('../../chrome-mac/Chromium.app/Contents/MacOS/Chromium')
        },
        staticDir: path.join(__dirname, 'dist'),
      })
    ]);
  }

  return config;
};

umi4中下面两种配置方式都不生效，不知为什么

方式一

const PrerenderSPAPlugin = require('prerender-spa-plugin-next')

const renderer = require('@prerenderer/renderer-puppeteer')
// 配置文件
  chainWebpack(memo, { env, webpack }) {
    // 添加额外插件
    if (env === 'production') {
      memo.plugin('prerender-spa-plugin-next').use(new PrerenderSPAPlugin({
        renderer,
        rendererOptions: {
          executablePath: path.resolve('../../chrome-mac/Chromium.app/Contents/MacOS/Chromium'),
        },
        staticDir: path.join(__dirname, 'dist'),
        routes: ['/', '/docs'],
      }));
    }
  },

方式二

const PrerenderSPAPlugin = require('prerender-spa-plugin-next')

const renderer = require('@prerenderer/renderer-puppeteer')
// 配置文件
chainWebpack(memo, { env, webpack }) {
    // 添加额外插件
      memo.plugin('prerender-spa-plugin-next').use(PrerenderSPAPlugin, [{
        renderer,
        rendererOptions: {
          executablePath: path.resolve('../../chrome-mac/Chromium.app/Contents/MacOS/Chromium'),
        },
        staticDir: path.join(__dirname, 'dist'),
        routes: ['/', '/docs'],
      }]);
    }
  },
