推荐答案
这是CasperJS和1.9.8版本的PhantomJS的一个已知问题.它不执行任何操作，并且错误仅在退出时打印.它们不会干扰您的脚本.有一种解决方法，它已合并到GitHub上的master分支中，但尚未作为CasperJS的发行版提供(最新版本为1.1-beta3).
This is a known issue with CasperJS and the 1.9.8 version of PhantomJS. It doesn't do anything and the errors are only printed during exit. They don't interfere with your script. There is a workaround and it was merged into master branch on GitHub, but it is not available as a release of CasperJS yet (latest is 1.1-beta3).
解决此问题的最简单的方法是降级到PhantomJS 1.9.7.由于您使用的是NPM，因此只需
The easiest way to solve this is to downgrade to PhantomJS 1.9.7. Since you're using NPM it is easily done with
npm -g install [email protected]
PhantomJS版本与NPM phantomjs软件包版本匹配，直到1.9.7，然后一切都中断了.您可以使用npm show phantomjs检查版本.
The PhantomJS versions match with the NPM phantomjs package versions up until 1.9.7, then everything breaks. You can check the versions with npm show phantomjs.
如果降级到1.9.7版，则对于请求https资源的站点，必须使用--ssl-protocol=any命令行选项运行.原因显示在我的答案中此处.
If you downgrade to version 1.9.7, you will have to run with the --ssl-protocol=any commandline option for sites that request https resources. The reason is shown in my answer here.
解决此问题的正确方法是从git 安装新版本.这样，您不仅可以使用没有附加错误行的PhantomJS 1.9.8，而且可以使用CasperJS 1.1-beta3无法实现的PhantomJS 2.
The proper way to solve this is to install a new version from git. This will enable you to not only use PhantomJS 1.9.8 without the additional error lines, but also PhantomJS 2 which would not be possible with CasperJS 1.1-beta3.
