【问题描述】：

我有一段代码可以打开一个新的弹出窗口并触发打印。打印工作正常，但是当我关闭弹出窗口时，应用程序崩溃并从我的终端显示“This is probably not a problem with npm. There is likely additional logging output above.”的错误

var img = jQuery("#imgWrap").html();
var popup = window.open();
console.log(popup);
popup.focus();
popup.document.write(img);
popup.print();

这是完整的日志输出

【问题讨论】：

也许尝试npm install 然后再次运行代码？如果还是不行，可能需要清除缓存，这种情况下，删除node_modules文件夹，运行npm cache verify，然后n运行npm install
There is likely additional logging output above." ... 那么上面还有额外的日志输出吗？如果可以，可以分享给我们吗？
在问题中添加了完整的日志输出:)
我很好奇你为什么将src 设置为#；你希望它做什么？
我只是把它放在示例代码中。我复制了我的代码并更改了我的问题以反映我的实际代码。

【解决方案1】：

对此有点挣扎，所以我试图改变我正在使用的 Electron 版本。在 Electron 9.3.1 上，它使用以下代码工作：

const electron = require('electron');
const BrowserWindow = electron.remote.BrowserWindow; 
let win = BrowserWindow.getFocusedWindow();

function print(){
   win.webContents.print({}, function(response){
     console.log(response);
   });
}
