类名称：Helper
方法名：compareVersions

Helper.compareVersions介绍

[英]INTERNAL: Compares two version in num.num.num.num.num*** format. -1, 0, 1 means the version1 is less than, equal, greater than version2. Example: compareVersions("11.1.0.6.0-Production", "11.1.0.7") == -1
[中]内部：比较num.num.num.num***格式的两个版本-1、0、1表示版本1小于、等于或大于版本2。示例：比较（“11.1.0.6.0-Production”、“11.1.0.7”）=-1
