我正试图在Meteor JS中从服务器端生成PDF。
我添加了meteorhacks：ssr，meteorhacks：首先是npm，我的构建成功了
当我向流星添加 bryanmorgan：webshot 并运行流星时，下面是我所面临的错误，

npm-container
bryanmorgan:webshot
答案 0 :(得分：2)
我将您的包列表复制到一个新的新项目中并出现了一些错误。所以首先我必须删除
meteor remove meteorhacks:npm
meteor remove npm-container
第一个被弃用，第二个被拒绝。
启动应用后，我收到以下错误：

这显然来自bryanmorgan：webshot包。
正如我之前评论的那样，bryanmorgan：webshot包使用了npm包webshot。所以我删除了bryanmorgan：webshot并添加了npm包：
meteor remove bryanmorgan:webshot
meteor npm install --save webshot
这使我的meteor服务器成功重启。
现在看看bryanmorgan：webshot并尝试创建我们自己的webshot：
webshot.js
import _webshot from 'webshot';
webshot = function (url, filePath, options, callback) {
var webshotAsync = Meteor.wrapAsync(_webshot);
var callback = [].slice.apply(arguments).pop();
if (typeof callback !== 'function') {
throw new Error("Missing callback function");
}
if (arguments.length === 2) {
return webshotAsync(url, callback);
} else if (arguments.length === 3) {
return webshotAsync(url, filePath, callback);
}
webshotAsync(url, filePath, options, callback);
};
webshot("http://google.com", "./tmp/google.png", function (err) {
// screenshot saved to /tmp/google.png
console.log(err);
});
运行良好，并根据需要创建一个webshot。
