终端 – 无法使用jenv在Mojave中设置不同的Java版本
作者:互联网
我希望在我的机器上有不同的Java版本.
我出于这个原因安装了jenv.但是,我无法为其设置所需的Java版本.实际上无法设置任何版本.
我安装了Java 8和11.我想将Java 8设置为全局
这是我试过的片段:

sdos-MacBook-Pro:~ nazar$java -version
openjdk version "11.0.1" 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.1+13)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)
我无法理解那里错过了什么.
如何用jenv设置Java 8?
解决方法:
我在终端执行:
echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(jenv init -)"' >> ~/.bash_profile
之后它可以配置jenv,如手册页中所述.但是,它没有生效:
sdos-MacBook-Pro:~ nazar$jenv versions
system
1.8
* 1.8.0.192 (set by /Users/nazar/.jenv/version)
11.0
11.0.1
openjdk64-11.0.1
oracle64-1.8.0.192
sdos-MacBook-Pro:~ nazar$java -version
openjdk version "11.0.1" 2018-10-16
只有在打开新终端后我才能看到:
sdos-MacBook-Pro:~ nazar$java -version
java version "1.8.0_192"
Java(TM) SE Runtime Environment (build 1.8.0_192-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.192-b12, mixed mode)
