Question

我在项目中使用ImageMagic。我没有为此安装其他任何东西。它在本地工作。

我目前创建了三个对象，但是并不总是创建图像，仅在构建时就不会在本地出现此类问题（yarn dev）。结果就是产品。

第1步

item = await Item.createObject(user, template);

第2步

...
public static async createObject(...) {
...
    for(...) {
        result = await this.createInstance(user, template);
        ...
    }
}

第3步

private static async createInstance(user, template) {
    ...
    const { imgName, description } = await Image.imageMagicCreate(...);
}

第4步

import * as shell from 'shelljs';
import * as fs from 'fs';
import * as appRoot from 'app-root-path';

// itemId - input data;

class Image {
public async imageMagicCreate(data: IMagicData) {

const userFolder = './uploads/' + user.userName;
const baseImage = appRoot.path + '/static/template.png';
if (!fs.existsSync(userFolder)) {
    fs.mkdirSync(userFolder);
}
const itemsFolder = userFolder + '/items';
if (!fs.existsSync(itemsFolder)) {
    fs.mkdirSync(itemsFolder);
}
const thumbsFolder = userFolder + '/thumbs/items';
if (!fs.existsSync(thumbsFolder)) {
    fs.mkdirSync(thumbsFolder);
}

shell.exec(
   `convert ${baseImage} -resize 420x380 \
   -gravity south \
   -fill '#5e6e87' -font Bookman-LightItalic -pointsize 14 -annotate +0+165 '${txtPart1}' \
    -fill '#5e6e87' -font Bookman-LightItalic -pointsize 14 -annotate +0+140 '${txtPart2}' \
    -fill '#5e6e87' -font Bookman-LightItalic -pointsize 14 -annotate +0+115 '${txtPart3}' \
    ${itemsFolder}/${itemId}.png`,
    {async: true},
    () => log('item created successfully'),
);

shell.exec(
   `convert ${baseImage} -resize 420x380 \
   -gravity south \
   -fill '#5e6e87' -font Bookman-LightItalic -pointsize 14 -annotate +0+165 '${txtPart1}' \
    -fill '#5e6e87' -font Bookman-LightItalic -pointsize 14 -annotate +0+140 '${txtPart2}' \
    -fill '#5e6e87' -font Bookman-LightItalic -pointsize 14 -annotate +0+115 '${txtPart3}' \
    ${thumbsFolder}/${itemId}.png`,
    {async: true},
    () => log('thumbnail created successfully'),
);
}
}

return {
     imgName: `${itemId}.png`,
     description,
};

在本地可以正常工作，但是如果我确实进行过构建，则无法正确执行工作，而不是从命令开始：

pm2 start ./eco.system....

我必须绘制6张图像，3张大3400 * 2600像素和3张缩略图420 * 360px。所有缩略图都被绘制，然后不是全部，然后是一张大图片，第二张被裁剪了，第三张是一个空文件，那么它根本就没有了……好像没有时间来绘制，但是好像是{async：true}设置。

总的来说，我发现了问题所在。所有代码都是正确的，问题出在这里，日志写给了我，但我不理解他们=（

在eco.system文件中，必须将选项watch从true更改为false。 here描述了类似的问题。

ImageMagic在本地工作，而不在内部工作
