我有一个使用 html-pdf 包的简单项目，我想用以下代码制作一个简单的 pdf 文件：

...
    pdf.create(html).toStream(function(err, stream){
            if (err) reject(err) ;
            else  stream.pipe(fs.createWriteStream(path.join(__dirname, '../../../assets/docs/idv_docs/')+data.link+'.pdf'));
          });
...

但我收到此错误消息：

Error: html-pdf: Received the exit code '1'

我有同样的问题，问题是 openssl.cnf 文件。
我的操作系统是 Debian 10。
尝试以下步骤
步骤 1：转到 /etc/ssl/openssl.cnf

第 2 步：找到以下行并对其进行注释。

# System default
openssl_conf = default_conf

第 3 步：重新启动节点服务器

我使用创建它为我工作

//pdf.js

const pdf = require('html-pdf');

function toPDF (html, options,  output) {
    return new Promise(function (resolve, reject) {
        pdf.create(html, options).toFile(output, function(error, response) {
            if (error) {
                reject(error);
            }
            else {
                resolve(response);
            }
        });
    });
}

module.exports = {
    toPDF: toPDF
}

使用时

const options = { format: 'A4', base: './assets' }
const fileName = `PDFDemo-${Date.now()}`
const output = `./pdf/${fileName}.pdf`
let pdfResult = await pdfUtil.toPDF(html, options, output)
