Hardware Requirements

  • 1GHz (or faster) x86 or x86_64 processor
  • 1 GB RAM
  • 250 MB hard disk space
  • 350 MB of temporary hard disk space during installation

Operating System Requirements

Supported operating systems:

The following platforms are officially supported.

Other operating systems:

Komodo may also run on other Linux based systems, or older versions of the supported operating systems listed above. You will need to verify compatibility yourself, because Komodo is not tested on these other platforms, and platform-specific bugs may exist.

  • FreeBSD (with Linux binary compatibility)
  • Gentoo

Software Prerequisites on Linux

Installation Prerequisites:

  • GTK+ 2.24 (or higher)
  • Glib 2.22 (or higher) - included in most standard Linux distributions.
  • Pango 1.14 (or higher)
  • X.Org 1.0 (or higher)
  • Libstdc++6
  • gdk-pixbuf (required on come platforms like Centos 6)
  • Gnome libraries (libgnome, libgnomeui)

Non-ASCII Input Requirements (IME):

  • SuSE: scim, scim-bridge-gtk and scim-bridge-qt packages.
  • Ubuntu: scim, scim-gtk2-immodule, scim-qtimm, and scim-tables-additional packages (if not already installed).
  • Fedora Core / RHEL / CentOS: scim, scim-gtk and scim-qtimm packages.

Adding Perl or Python to the PATH Environment Variable

To add Perl or Python to the PATH environment variable, do one of the following:

  • Modify your PATH environment variable. For example, if you use the Bash shell, add the following line to your ~/.bashrc file, where <installdir> points to the directory where you installed ActivePerl or ActivePython:
export PATH=<installdir>/bin:$PATH
  • Create a symbolic link to the Perl or Python executable, where <installdir> points to the directory where you installed ActivePerl or ActivePython.

For ActivePerl, enter:

ln -s <installdir>/bin/perl /usr/local/bin/perl
  • For ActivePython, enter:
ln -s <installdir>/bin/python /usr/local/bin/python

Installing the Komodo License on Linux

NOTE This only applies for Komodo 11.1.0 and lower. Version 11.1.1 and higher are integrated with the ActiveState Platform and do not use the license installer. For more information, see Komodo and the ActiveState Platform.

Komodo IDE comes with a 21-day trial license. To install a permanent license:

  • Download the license installer from the My Account page.
  • Change the permissions on the downloaded file to allow execution (e.g. chmod +x Komodo-<version>-<license#>.executable)
  • Run the installer (e.g. ./Komodo_<version>_<license#>.executable).

Upgrading from Previous Komodo Versions

Newer versions of Komodo should not be installed in the same directory as older versions. For major release upgrades (e.g. x.1 to x+1.0) the installer will automatically put Komodo in a new directory.

For minor releases (e.g. x.0 to x.1) and patch-level releases (x.1.1 to x.1.2), use the auto-update system (Help > Check for Updates). The changes will be applied safely in the current install directory. If you need to update using an installer, completely uninstall the older version before installing the new one, or manually specify a different install directory during the installation process. Your Komodo preferences will be preserved as they are installed in a different directory.

Installing Komodo on Linux

This version of Komodo allows non-root installation on Linux.

To install Komodo on Linux:

  1. Download the Komodo installer (.tar.gz file) into a convenient directory.
  2. Unpack the tarball:

    tar -xvzf Komodo-<version>-<platform>.tar.gz
  3. Change to the new directory:

    cd Komodo-<version>-<platform>
  4. Run the install script (

  5. Answer the installer prompts:

  6. Specify where you want Komodo installed, or press ‘Enter’ to accept the default location (/home/<username>/Komodo-<IDE|Edit>-x.y).The -I option can be used to specify the install directory. For example:

    ./ -I ~/opt/Komodo-IDE-11

If multiple users are sharing the system and will be using the same installation, install Komodo in a location every user can access (e.g. /opt/Komodo-x.x/ or /usr/local/Komodo-x.x/).


  • Each Komodo user requires their own license key.
  • Do not install Komodo in a path that contains spaces or non-alphanumeric characters.
  • Be sure to install Komodo into its own directory (i.e. not directly in an existing directory containing shared files and directories such as /usr/local).

Once the installer has finished, add Komodo to your PATH with one of the following:

  • Add Komodo/bin to your PATH directly:

    export PATH=<installdir>/bin:$PATH
  • Add a symlink to Komodo/bin/komodo from another directory in your PATH:

    ln -s <installdir>/bin/komodo /usr/local/bin/komodo

Note: Creating symlinks in system directories such as /usr/bin requires root access.

After completing the installation, you can delete the temporary directory where the Komodo tarball was unpacked.

Starting Komodo on Linux

To start Komodo on Linux enter komodo at the command line or create a shortcut on your desktop or in your toolbar using the full path to the komodo executable.

Uninstalling Komodo on Linux

To uninstall Komodo on Linux:

  1. Delete the directory that Komodo created during installation.
  2. If you wish to delete your Komodo preferences, delete the ~/.komodo directory. If you do not delete this directory, subsequent installations of Komodo will use the same preferences.

Note: You cannot relocate an existing Komodo installation to a new directory by simply moving it. You must uninstall Komodo from the existing location and reinstall it in the new location.
