node.js - 在 Eclipse 中向 Cordova 应用程序添加平台时出错

Question

在 Eclipse (Mars) 中创建新的 Cordova 项目后，当我单击“完成”时，它开始向我的应用程序添加平台，但最终抛出以下错误并且未添加平台:

X:\CordovaWorkspace\DemoProject>cordova prepare Discovered platform
"android@5.3.0-nightly.2016.7.6.103e1e8d" in config.xml. Adding it to

如何解决。

Answer 1

尝试通过下载 sax 模块并将其放在名为 sax 的文件夹中来手动解决 sax 要求。

或使用npm install如果您在互联网上找不到 sax mmodule，您可以在 node-elementtree/lib/parsers/sax.js 中创建 sax.js 并将此代码放在下面:

var util = require('util');

var sax = require('sax');

var TreeBuilder = require('./../treebuilder').TreeBuilder;

function XMLParser(target) {
  this.parser = sax.parser(true);

  this.target = (target) ? target : new TreeBuilder();

  this.parser.onopentag = this._handleOpenTag.bind(this);
  this.parser.ontext = this._handleText.bind(this);
  this.parser.oncdata = this._handleCdata.bind(this);
  this.parser.ondoctype = this._handleDoctype.bind(this);
  this.parser.oncomment = this._handleComment.bind(this);
  this.parser.onclosetag = this._handleCloseTag.bind(this);
  this.parser.onerror = this._handleError.bind(this);
}

XMLParser.prototype._handleOpenTag = function(tag) {
  this.target.start(tag.name, tag.attributes);
};

XMLParser.prototype._handleText = function(text) {
  this.target.data(text);
};

XMLParser.prototype._handleCdata = function(text) {
  this.target.data(text);
};

XMLParser.prototype._handleDoctype = function(text) {
};

XMLParser.prototype._handleComment = function(comment) {
};

XMLParser.prototype._handleCloseTag = function(tag) {
  this.target.end(tag);
};

XMLParser.prototype._handleError = function(err) {
  throw err;
};

XMLParser.prototype.feed = function(chunk) {
  this.parser.write(chunk);
};

XMLParser.prototype.close = function() {
  this.parser.close();
  return this.target.close();
};

exports.XMLParser = XMLParser;
