在github裏下載了zip壓縮包，將kotlin-compiler-1.3.72.zip習慣性地解壓到了D:\Program Files\kotlinc，將此路徑配置到系統環境變量path路徑後，打開cmd，執行"kotlinc -help"後報如下錯誤：
C:\Users\Administrator>kotlinc
錯誤: 找不到或無法加載主類 org.jetbrains.kotlin.preloading.Preloader
問題出在kotlinc編譯器的安裝路徑，D:\Program Files\kotlinc中存在空格。將kotlinc解壓包轉移到其他沒有空格的路徑下，更新環境變量路徑，重新打開cmd執行"kotlinc -help"：
C:\Users\Administrator>kotlinc -help
