Here is trial and error logs when installing Pycharm.

# tail -1 /etc/lsb-release DISTRIB_DESCRIPTION="Ubuntu 13.10" root@ubuntu:~# uname -ri 3.11.0-12-generic x86_64 root@ubuntu:~# python --version Python 2.7.5+

download pycharm from http://www.jetbrains.com/pycharm/

I downloaded community edition.

# tar xzvf pycharm-community-3.0.1.tar.gz # cd pycharm-community-3.0.1/bin

need JDK to run pycharm.

# ./pycharm.sh ERROR: Cannot start PyCharm No JDK found. Please validate either PYCHARM_JDK, JDK_HOME or JAVA_HOME environment variable points to valid JDK installation.

[ install oracleJDK]

install oracle jdk instead of open JDK.

# tar xzvf jdk-7u45-linux-x64.tar.gz # mkdir /usr/local/java # mv jdk1.7.0_45 /usr/local/java/

configure JAVA_HOME and add the path for jdk1.7.

# cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/java/jdk1.7.0_45" JAVA_HOME=/usr/local/java/jdk1.7.0_45 export JAVA_HOME

configure jdk1.7.0 as default

when using openjdk, you will see following warning.

I could use pycharm with open JDK, however I installed oracle JDK.

$ ./pycharm.sh 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.

[ run pycharm ]

after installing oracle JDK, run pycharm.sh

configure which python version you use

gui -> configure -> settings -> python interpreters

create a new project

then create a python file ( right click “project name” -> new -> python file )
