在C#项目中部署CasperJS

Question

Tl:dr - 如何从C#项目文件夹中引用CasperJS和PhantomJS？

当我手动将CasperJS和PhantomJS的二进制文件解压缩到C:驱动器时,我有从C#项目运行CasperJS脚本的工作代码.(请参阅此处获取标签为WORKING Code的简单指南和工作代码:)

由于没有安装需要我认为这将是很容易将这些移动到C#项目文件夹,而不是\tools\casperjs和\tools\phantomjs.另外,我需要在代码中使用更新PATH变量p.StartInfo.EnvironmentVariables["PATH"] = EnvPath;

我尝试的所有路径组合都会出现以下错误 "Fatal: [Errno 2] No such file or directory; did you install phantomjs?"

所有文件都已包含在文件路径中.我错过了一些明显的东西吗

var casper = require('casper').create();

casper.start('http://casperjs.org/', function() {
    this.echo(this.getTitle());
});

casper.thenOpen('http://phantomjs.org', function() {
    this.echo(this.getTitle());
});

casper.run();

成功了。只需确保正确复制所有必需的资源即可。package.json我错过了文件路径中的文件C:\casperjs\n1k0-casperjs-4f105a9
