如何在React Native Fs中重命名/移动文件夹？

我在重命名和移动文件夹时遇到了麻烦，因为React Native fs仅具有仅对文件而不对文件夹执行的moveFile选项。递归也很麻烦，由于同步执行，在执行重命名或移动选项后很难执行行。已将错误的附加代码附在下面。请帮我解决这个问题。

moveAll = (path, outputPath) => new Promise((resolve, reject) => {
// is a folder
if (path.split(".").length == 1) {
  // CHeck if folder already exists
  RNFS.exists(outputPath)
    .then((exists) => {
      if (exists) {
        // Delete the folder if exists
        RNFS.unlink(outputPath)
          .then(() => {

          })
          // `unlink` will throw an error, if the item to unlink does not exist
          .catch((err) => {
            console.log(err.message);
          });
      }
      // MAKE FRESH FOLDER
      RNFS.mkdir(outputPath);
      resolve(RNFS.readDir(path)
        .then((result) => {
          result.map(
            (item) =>
              new Promise((resolve, reject) => {
                resolve(this.moveAll(item.path, outputPath + "/" + item.name));
              })
          )
        })
        .catch((e) => {
          console.log("ERROR", e)
        })
      )
    })
    .catch((e) => {
      console.log(e)
    })

} else {
  RNFS.moveFile(path, outputPath)
    .then(() => {
    })
    .catch((e) => {
      console.log(e)
    })
}
})

感谢您的帮助，我为您的解决方案找到了答案

moveAll = async (path, outputPath) => {
    // is a folder
    if (path.split(".").length == 1) {
      // CHeck if folder already exists
      var exists = await RNFS.exists(outputPath);
      if (exists) {
        await RNFS.unlink(outputPath);
        await RNFS.mkdir(outputPath);
      }
      // MAKE FRESH FOLDER
      var result = await RNFS.readDir(path);
      for (var i = 0; i < result.length; i++) {
        if (result[i].isDirectory()) {
          await RNFS.mkdir(outputPath + "/" + result[i].name);
        }
        var val = await this.moveAll(result[i].path, outputPath + "/" + result[i].name);
      }
      await RNFS.unlink(path);
      return 1;
    } else {
      await RNFS.moveFile(path, outputPath);
      return 1;
    }
  }
