错误-在ubuntu中安装JDK 1.8

Question

我试着安装jdk 8，但是它仍然适用于jdk 7。

sudo更新-选项--配置javac

There is 1 choice for the alternative javac (providing /usr/bin/javac).

  Selection    Path                                 Priority   Status
------------------------------------------------------------
  0            /opt/java-oracle/jdk1.8.0/bin/javac   1         auto mode
* 1            /opt/java-oracle/jdk1.8.0/bin/javac   1         manual mode

sudo更新-选项-配置java

* 1            /opt/java-oracle/jdk1.8.0/bin/java   1         manual mode

javac -version

Error: could not find libjava.so
Error: Could not find Java SE Runtime Environment.

java -version

java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

如果你能帮忙的话。谢谢:)

参考下面的链接，我的链接运行良好&我安装了JDK 8，引用链接。

我想你错过了javac的更新-替代品。

update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.8*/bin/javac 1065

JDK 8安装
