安装kotlin命令行编译器出现错误“找不到或无法加载主类 or

  在github里下载了zip压缩包，将kotlin-compiler-1.2.50.zip习惯性地解压到了D:\Program Files\kotlinc，将此路径配置到系统环境变量path路径后，打开cmd，执行"kotlinc -help"后报如下错误：

C:\Users\Administrator.000>kotlinc -help
错误: 找不到或无法加载主类 org.jetbrains.kotlin.preloading.Preloader

  问题出在kotlinc编译器的安装路径，D:\Program Files\kotlinc中存在空格。将kotlinc解压包转移到其他没有空格的路径下，更新环境变量路径，重新打开cmd执行"kotlinc -help"：

C:\Users\Administrator.000>kotlinc -help
