casperjs找不到phantomjs [英] casperjs does not find phantomjs

问题描述

我已经下载了最新版本的casperjs(1.03)和phantomjs(1.9.2).

I've downloaded the latest version of casperjs (1.03) and phantomjs (1.9.2).

所以我从casper页面上提取了这个简单的脚本:

So I took this little simple script from the casper page:

var casper = require('casper').create({
    verbose: true,
    logLevel: "debug"
});
var casper = new require('casper').Casper();

当我尝试运行它时，出现以下错误:

and when I try to run it I get the following error:

noname:phantomjs-1.9.2 Tom$ casperjs/bin/casperjs tipico2.js 
Fatal: [Errno 2] No such file or directory; did you install phantomjs?

所以，这是我的目录结构:

So, this is my directory structure:

phantomjs-1.9.2/ <-- the folder containing phantomjs
phantomjs-1.9.2/casperjs/ <-- a subfolder containting casperjs

为什么不起作用?

推荐答案

解决方案实际上非常简单.只需导出phantomjs二进制文件所在的路径即可.在我的情况下，这是/Users/Tom/Downloads/phantomjs-1.9.2/bin，因此

The solution is actually very simple. Just export the path where the binary of phantomjs is. In my case this is /Users/Tom/Downloads/phantomjs-1.9.2/bin, hence

export PATH=$PATH:/Users/Tom/Downloads/phantomjs-1.9.2/bin
