This is the translated issue:

When common/logger.js platform is not ios or android, cmd will be an empty string, resulting in an error.

I want to use nosmoke to do the web-pc traversal test. I found that I will report an error and finally locate it in common/logger.js.
The error message is as follows
TypeError: "file" argument must be a non-empty string
    At normalizeSpawnArguments (child_process.js:384:11)
    At exports.spawn (child_process.js:497:38)

-----> Crawling Finished: <-----
 TypeError: "file" argument must be a non-empty string

Comment out the logger.filterDeviceLogs(root.config) in index.js;
The nosmoke command can be run normally. When all the a tags are clicked in the configuration file, the actual operation can open the page, but no click operation occurs. Can you help me to see what the problem is?

logger 的问题不影响pc-web 下的爬行实现， 应该是别的问题. 此处exception会修复

Logger problem does not affect the crawl achieved in pc-web, it should be another question. Here exception will be fixed
