node.js - 使用 `ncp` 复制文件会抛出：没有这样的文件或目录，mkdir

Question

我ncp用来复制文件如下：

import ncp from "ncp";
import { promisify } from "util";

const ncpPromise = promisify(ncp);
const copyAssets = async (exportFolderName, includeSourceMaps) => {
  const assets = glob.sync("**/", { cwd: distPath });
  const options = { clobber: true, stopOnErr: true };
  if (!includeSourceMaps) {
    options.filter = (f) => {
      return !f.endsWith(".map");
    };
  }
  return Promise.all(
    assets.map((asset) => {
      return ncpPromise(
        path.join(distPath, asset),
        path.join(exportPath, exportFolderName, asset),
        options
      );
    })
  );
};

但这有时会失败并出现以下错误：

"ENOENT: no such file or directory, mkdir '/path/to/folder'"

我该如何解决这个问题？

Answer 1

我猜您正在尝试复制与给定 glob 匹配的所有文件，因此您需要执行以下操作：

const assets = glob.sync("**/*.*", { cwd: distPath }); // note the *.*

例如，您当前的问题将导致：

[
  'folder1/',
  'folder2/',
]

而这个答案中的 glob 将导致（这就是你想要的）：

[
  'folder1/file1.txt',
  'folder1/file2.txt',
  'folder2/anotherfile.txt',
]

替代：

似乎没有维护ncp 。因此，您可以使用fs-extra，它也可以复制文件和目录：

const glob = require("glob");
const path = require("path");
const fs = require("fs-extra");

const copyAssets = async (exportFolderName, includeSourceMaps) => {
  const assets = glob.sync("**/*.*", { cwd: distPath });

  const options = { overwrite: true };

  if (!includeSourceMaps) {
    options.filter = (f) => {
      return !f.endsWith(".map");
    };
  }

  return Promise.all(
    assets.map((asset) => {
      return fs
        .copy(
          path.join(distPath, asset),
          path.join(exportPath, exportFolderName, asset),
          options
        )
        .catch((e) => console.log(e));
    })
  );
};
