在我的节点应用程序中,我需要删除一个目录,其中有一些文件,但fs。Rmdir只适用于空目录。我该怎么做呢?


当前回答

如果你更喜欢async/await,你可以使用fs/promises API。

const fs = require('fs/promises');

const removeDir = async (dirPath) => {
  await fs.rm(dirPath, {recursive: true});
}

如果您知道文件夹中单个文件的路径,并希望删除包含该文件的文件夹。

const fs = require('fs/promises');
const path = require('path');

const removeDir = async (filePath) => {
  const { dir } = path.parse(filePath);
  await fs.rm(dir, { recursive: true });
}

其他回答

return new Promise((resolve, reject) => {
  const fs = require("fs");
  // directory path
  const dir = "your/dir";

  // delete directory recursively <------
  fs.rmdir(dir, { recursive: true }, (err) => {
    if (err) {
      reject(err);
    }
    resolve(`${dir} is deleted!`);
  });
});

从Node.js 14.14.0开始,推荐使用fs.rmSync:

fs.rmSync(dir, { recursive: true, force: true });

同步文件夹删除文件或仅一个文件。 我不是一个很好的给予者,也不是一个贡献者,但我找不到一个很好的解决这个问题的方法,我必须找到我的方法……所以我希望你会喜欢它:) 适用于任何数量的嵌套目录和子目录。注意递归函数时'this'的作用域,您的实现可能不同。在我的例子中,这个函数保留在另一个函数的返回中这就是为什么我用这个来调用它。

    const fs = require('fs');

    deleteFileOrDir(path, pathTemp = false){
            if (fs.existsSync(path)) {
                if (fs.lstatSync(path).isDirectory()) {
                    var files = fs.readdirSync(path);
                    if (!files.length) return fs.rmdirSync(path);
                    for (var file in files) {
                        var currentPath = path + "/" + files[file];
                        if (!fs.existsSync(currentPath)) continue;
                        if (fs.lstatSync(currentPath).isFile()) {
                            fs.unlinkSync(currentPath);
                            continue;
                        }
                        if (fs.lstatSync(currentPath).isDirectory() && !fs.readdirSync(currentPath).length) {
                            fs.rmdirSync(currentPath);
                        } else {
                            this.deleteFileOrDir(currentPath, path);
                        }
                    }
                    this.deleteFileOrDir(path);
                } else {
                    fs.unlinkSync(path);
                }
            }
            if (pathTemp) this.deleteFileOrDir(pathTemp);
        }

2020年更新

从12.10.0版本开始,为选项添加了recursiveOption。

注意,递归删除是实验性的。

所以你会做同步:

fs.rmdirSync(dir, {recursive: true});

或者async:

fs.rmdir(dir, {recursive: true});

方法删除非空目录

rmdir(path,{recursive:true,force:true}
rm(path,{recursive:true,force:true}

将工作

代码片段:

const fsp = require("fs/promises");

deleteDirRecursively("./b");
removeRecursively("./BCD/b+");

async function deleteDirRecursively(dirPath) {
  try {
    // fsPromises.rmdir() on a file (not a directory) results in the promise being rejected
    // with an ENOENT error on Windows and an ENOTDIR error on POSIX.
    // To get a behavior similar to the rm -rf Unix command,
    // use fsPromises.rm() with options { recursive: true, force: true }.
    //will not thorw error if dir is empty
    //will thow error if dir is not present
    await fsp.rmdir(dirPath, { recursive: true, force: true });
    console.log(dirPath, "deleted successfully");
  } catch (err) {
    console.log(err);
  }

async function removeRecursively(path) {
  try {
    //has ability to remove both file and dir
    //can delete dir recursively and forcefully
    //will delete an empty dir.
    //will remove all the contents of a dir.
    // the only difference between rmdir and rm is that rmdir can only delete dir's
    await fsp.rm(path, { recursive: true, force: true });
    console.log(path, "deleted successfully");
  } catch (err) {
    console.log(err);
  }
}
