Pycharm安装抱怨OpenJDK
我尝试在Ubuntu 12.04上安装Pycharm,我有以下信息:
user@user:~/Pobrane/pycharm-2.5.2/bin$ sh pycharm.sh
OpenJDK Runtime Environment (IcedTea6 1.11.1) (6b24-1.11.1-4ubuntu3)
OpenJDK Server VM (build 20.0-b12, mixed mode)
WARNING: You are launching the IDE using OpenJDK Java runtime.
ITS KNOWN TO HAVE PERFORMANCE AND GRAPHICS ISSUES!
SWITCH TO THE ORACLE(SUN) JDK BEFORE REPORTING PROBLEMS!
NOTE: If you have both Oracle (Sun) JDK and OpenJDK installed
please validate either PYCHARM_JDK, JDK_HOME, or JAVA_HOME environment variable points to valid Oracle (Sun) JDK installation.
See http://ow.ly/6TuKQ for more info on switching default JDK.
Press Enter to continue.
如何正常工作?
