无法运行yarn start命令

[gittig11]

安装依赖，运行yarn start后，报错：

fs.js:474
  handleErrorFromBinding(ctx);
  ^

node版本 14.13.1

原因未知...

遇到跟你一样的问题, run build 和 start 都是 包跟你一样的错误, ENOENT: no such file or directory, open 'C:...\registry.npmmirror.com+markdown-to-html-cli@3.1.6\node_modules\markdown-to-html-cli\package.json'
不管是npm 还是 pnpm 都一样是报这个错
node v14.16.1
npm v7.23.0
pnpm v6.23.1

@gittig11 @waytoviva 我在 macOS 上没有问题。没有 windows 电脑，没有办法调试，尝试解决方案。

➜  linux-command git:(master) npm -v
7.23.0
➜  linux-command git:(master) node -v
v14.17.5
➜  linux-command git:(master) rm -rf package-lock.json node_modules
➜  linux-command git:(master) npm i

@jaywcjlove 找到原因了，markdown-to-html-cli v3.1.6代码有问题，

lib/index.js 中，应为：

// const pkg = fs.readJSONSync(path.resolve(/file:\/\/(.+)\/[^/]/.exec(import.meta.url)[1], '..', 'package.json'));
const pkg = fs.readJSONSync(path.resolve(/file:\/\/\/(.+)\/[^/]/.exec(import.meta.url)[1], '..', 'package.json'));

lib/create.js中，

let cssStr = fs.readFileSync(path.resolve(/file:\/\/\/(.+)\/[^/]/.exec(import.meta.url)[1], 'styles', 'github.css')).toString();
if (options['github-corners-fork'] && options['github-corners']) {
  let cssFork = fs.readFileSync(path.resolve(/file:\/\/\/(.+)\/[^/]/.exec(import.meta.url)[1], 'styles', 'github-fork-ribbon.css')).toString();
  cssStr = `${cssStr}${cssFork}`;
}

至于
const pkg = fs.readJSONSync(path.resolve(__dirname, '..', 'package.json'));
经过转译后是：
const pkg = fs.readJSONSync(path.resolve(/file:\/\/(.+)\/[^/]/.exec(import.meta.url)[1], '..', 'package.json'));
为什么这里的路径有问题，时间原因没有深入了解。

https://nodejs.org/api/esm.html#esm_no_require_exports_module_exports_filename_dirname

我好像找到原因了。

These CommonJS variables are not available in ES modules.
__filename and __dirname use cases can be replicated via import.meta.url.
