DEP0137：在垃圾回收时关闭 fs.FileHandle

【DEP0137: Closing fs.FileHandle on garbage collection】

类型：寿命终止

【Type: End-of-Life】

以前允许在垃圾回收时关闭 fs.FileHandle 对象，但现在会抛出错误。

【Allowing a fs.FileHandle object to be closed on garbage collection used to be allowed, but now throws an error.】

请确保在不再需要 fs.FileHandle 时，使用 FileHandle.prototype.close() 显式关闭所有 fs.FileHandle 对象：

【Please ensure that all fs.FileHandle objects are explicitly closed using FileHandle.prototype.close() when the fs.FileHandle is no longer needed:】

const fsPromises = require('node:fs').promises;
async function openAndClose() {
  let filehandle;
  try {
    filehandle = await fsPromises.open('thefile.txt', 'r');
  } finally {
    if (filehandle !== undefined)
      await filehandle.close();
  }
} 拷贝
