zookeeper報錯 JAVA_HOME is not set

自己在安裝zookeeper的時候發現到這么一個問題： JAVA_HOME is not set
原因在於zookeeper需要JAVA的環境

• 電腦如果沒有安裝JAVA環境的話，可以去官網下載jdk安裝，同時在系統的環境變量中設置。變量值填的是自己的安裝目錄
  

• 電腦安裝了JAVA環境如果還報這種錯誤的話，可以將zookeeper目錄下 /bin/zkEnv.cmd 以記事本方式打開

REM for sanity sake assume Java 1.6
REM see: http://java.sun.com/javase/6/docs/technotes/tools/windows/java.html
 
REM add the zoocfg dir to classpath
set CLASSPATH=%ZOOCFGDIR%
 
REM make it work in the release
SET CLASSPATH=%~dp0..\*;%~dp0..\lib\*;%CLASSPATH%
 
REM make it work for developers
SET CLASSPATH=%~dp0..\build\classes;%~dp0..\build\lib\*;%CLASSPATH%

@REM setup java environment variables
 
if not defined JAVA_HOME (
  echo Error: JAVA_HOME is not set.
  goto :eof
)
 
set JAVA_HOME=%JAVA_HOME:"=%
 
if not exist "%JAVA_HOME%"\bin\java.exe (
  echo Error: JAVA_HOME is incorrectly set.
  goto :eof
)
 
set JAVA="%JAVA_HOME%"\bin\java

將 set JAVA_HOME=%JAVA_HOME:"=% 修改為 set JAVA_HOME=D:\Environment\Java-jdk-17.0.2(你自己的安裝目錄) (注意，這里不能有"", 且這條命令一定要在 if 判斷之前)
