Linux-ubuntu R Unable to install Rjava module causes and solutions

Error message:

No/usr/lib/jvm/default-java/jre/bin/java.

Reason:

R cannot find Java as a dependency

Solution:

(1) If you do not have Java installed, please install Java first.

(2) View the version of Java in the terminal.

(3) Manually create the Default-java folder under/USR/LIB/JVM

(4) Find the folder of the Java environment displayed in the terminal (default in/USR/LIB/JVM, I have Oraclejava and Openjava, and I use Oraclejava)

(5) Manually copy all contents of the Java Environment folder to the Default-java folder.

Reference code: sudo cp-r/usr/lib/jvm/java-8-oracle/*/usr/lib/jvm/default-java

Remind:

Sometimes Rstudio can not install the module because of lack of authority, it is recommended to install manually under the terminal sudo R.
