linux - macbook tomcat configuration problem?

Question

When the macbook system configures tomcat, it appears:

Unable to find any JVMs matching version "(null)".
No Java runtime present, try --request to install.
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variables is needed to run this program

How to deal with it

Answer 1

First make sure the JDK is installed and the Java environment variables are configured properly.
Verification method:
Enter in the terminal

java -version

It is normal if the corresponding version number is displayed, otherwise please install JDK and configure Java environment variables first.

Answer 2

tomcat runs in jvm, you need to install jdk first.
