从节点脚本内的路径列表中调用类的静态方法？

Question

问题：

如何获取文件Array<string>的路径列表：

// ['apps/morningharwood/src/app/app.component.ts',
//  'apps/morningharwood/src/app/app-shell/app-shell.component.ts']

对于每条路径，在节点上调用静态方法ref.SomeStaticMethod()？

注意：我正在为节点（如果重要）和 windows 10 使用打字稿。

async function prePublish() {

  const componentPaths = await globby('apps/morningharwood/src/app/**/*.component.ts');
  const dirPaths = componentPaths.map(i => `./${i.split('.ts')[ 0 ]}`);
  console.log(dirPaths);
  /**
   * Logs out this
   * [ './apps/morningharwood/src/app/app.component',
   *   './apps/morningharwood/src/app/app-shell/app-shell.component' ]
   */
  const ref = await import('./apps/morningharwood/src/app/app.component');
  const ref2 = await import('./apps/morningharwood/src/app/app-shell/app-shell.component');
  console.log(ref, ref2); // WORKS AS INTENDED

  for (const dp of dirPaths) {
    console.log(dp); // ./apps/morningharwood/src/app/app.component
    const ref3 = await import(dp); // ERROR?

    console.log(ref); // Never runs.
  }
}
prepublish();

模块路径相对于当前模块进行解析，文件系统路径相对于当前工作目录进行解析。

考虑到路径已被 glob 成功匹配，apps/... 相对于当前工作目录，可能是项目根目录。依赖当前工作目录本身就是有问题的做法。为了保持一致性，全局和模块路径都可以明确说明。

可以是：

  const componentPaths = await globby('../apps/morningharwood/src/app/**/*.component.ts', { cwd: __dirname });
  for (const path of componentPaths) {
    const ref = await import(path.join('./', path));
    ...

或者：

  const componentPaths = await globby(path.join(__dirname, '../apps/morningharwood/src/app/**/*.component.ts'));
  for (const path of componentPaths) {
    const ref = await import(path);
    ...
