Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /Users/wangchengxiang/.config/yarn/global/node_modules/mdast-util-toc/index.js
require() of ES modules is not supported.
require() of /Users/wangchengxiang/.config/yarn/global/node_modules/mdast-util-toc/index.js from /Users/wangchengxiang/.config/yarn/global/node_modules/@rcpress/markdown/src/index.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 /Users/wangchengxiang/.config/yarn/global/node_modules/mdast-util-toc/index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/wangchengxiang/.config/yarn/global/node_modules/mdast-util-toc/package.json.

貌似一部分是用commjs的，一部分是es6的模块功能

node 版本v12.18.1

找到原因了，mdast-util-toc 6.0+只支持es module，可以暂时指定mdast-util-toc的版本为5.0+
