所以我使用Meteor包meteorhacks:npm以便在我的流星代码中使用npm包。所以我有一个模板:
Template.upload.events({
'submit form': function(event){
var file1 = document.getElementById("file1").files;
var file2 = $('[name=file1]').val();
//console.log(file1[0].type);
var reader = new FileReader();
reader.onload = function(event) {
var contents = event.target.result;
Meteor.call("saveFileinFolder",contents);
//console.log(contents);
};
这就是我打电话的Meteor方法:
Meteor.methods({
saveFileinFolder: function (content){
var nodeFS = Meteor.npmRequire('node-fs');
var fs = new nodeFS({version:'0.1.7'});
console.log(content);
}
});
我尝试使用节点包node-fs将文件保存到文件夹,但我一直收到错误:

你误解了使用meteorhacks的方式:npm。您需要将所需的版本号放入名为packages.json
的文件中:
{“node-fs”:“0.1.7”}
然后重新启动meteor,它将为您安装该节点包。然后在您的代码中,按照常规require
进行操作,只需使用Meteor.npmRequire
即可。您将获得与节点中的require
相同的对象。
