承诺未得到解决，尽管它被期待已久的

我想从一些图像得到的像素，并返回它们作为一个数组。对于图像处理我用。有服从跳异步函数jimp.read(filePath)需要得到与AWAIT处理。我的图像读取模块：

const config = require('./configuration.json');
const fs = require('fs');
const path = require('path');
const jimp = require('jimp');

module.exports = readImages;

function readImages() { // Reads the image files and extracts the colors
    const files = getFilesFromDirectory();
    const imageFiles = filterForImageFiles(files);
    return getInformationFromImageFiles(imageFiles);
}

function getFilesFromDirectory() { // Reads all the files from the directory provided from the configuration file
    return fs.readdirSync(config.dirPath);
}

function filterForImageFiles(files) { // Filters an array of files for .png and .jpg files
    return files.filter(file => {
        const fileExtension = path.extname(file);
        const isPngFile = fileExtension === '.jpg';
        const isJpgFile = fileExtension === '.png';
        return isPngFile || isJpgFile;
    });
}

function getInformationFromImageFiles(imageFiles) { // Maps image files to image information
    return imageFiles.map(imageFile => getInformationFromImageFile(imageFile));
}

async function getInformationFromImageFile(imageFile) { // Extracts information from an image file
    const filePath = path.join(config.dirPath, imageFile);
    const image = await jimp.read(filePath);
    return getColorsFromImage(image);
}

function getColorsFromImage(image) { // Extracts the colors from an image file
    const { width, height } = image.bitmap;
    const colors = [,];
    for (let x = 0; x < width; x++) {
        for (let y = 0; y < height; y++) {
            const intColor = image.getPixelColor(x, y);
            const rgbaColor = jimp.intToRGBA(intColor);
            colors[x, y] = rgbaColor;
        }
    }
    return colors;
}

当我运行代码我接收与两个项目的阵列（因为我提供了两个图像）。两者都是Promise { <pending> }。请看看getInformationFromImageFile这是一个async功能等待读者服从跳。

为什么它返回一个承诺，不解决这个问题？我必须等待每一个函数和整个模块...？

作为getInformationFromImageFile标记async它会返回一个Promise因此必须等待。你需要await它被调用。这些变化应该修复它：

async function getInformationFromImageFiles(imageFiles) {
    const imageInfos = [];
    for (let i = 0; i < imageFiles.length; i++) {
        const imageFile = imageFiles[i];
        imageInfos.push(await getInformationFromImageFile(imageFile));
    }

    return imageInfos;
}

async function readImages() {
    const files = getFilesFromDirectory();
    const imageFiles = filterForImageFiles(files);
    return await getInformationFromImageFiles(imageFiles);
}
