Vuepress打包时出现 Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: lodash-es/lodash.js

错误信息如下：

✖ Rendering pages - failed
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /Users/xxx/vueProjects/my-blog/node_modules/lodash-es/lodash.js
require() of ES modules is not supported.
require() of /Users/xxx/vueProjects/my-blog/node_modules/lodash-es/lodash.js from /Users/xxx/vueProjects/my-blog/docs/.vuepress/blog/.server/app.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename lodash.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/xxx/vueProjects/my-blog/node_modules/lodash-es/package.json.

解决方案

删除 node_modules/lodash-es/package.json 文件下

"type": "module",
