When encountering the error “OSError: cannot load library ‘gobject-2.0-0’: error 0x7e” and ctypes.util.find_library() cannot locate the ‘gobject-2.0-0’ library, it usually means that the required library is missing or not properly installed on your system. This error is commonly seen when trying to import modules that depend on the GObject library.
The GObject library is a part of the GTK+ toolkit, which is used for creating graphical user interfaces in applications. To resolve this issue, you will need to install the necessary runtime libraries for GObject. Here’s how you can do it on different operating systems:
On Debian-based Linux distributions:
$ sudo apt-get install libgirepository1.0-dev
$ sudo apt-get install libcairo2-dev
$ sudo apt-get install gir1.2-gtk-3.0
On RPM-based Linux distributions:
$ sudo dnf install gobject-introspection-devel
$ sudo dnf install cairo-devel
$ sudo dnf install gtk3-devel
On Windows:
- Download the GObject introspection runtime installer from the official website: https://gi.readthedocs.io/en/latest/installation.html#windows
- Run the downloaded installer and follow the installation instructions.
- Make sure the installed binaries are added to your system’s PATH environment variable.
After installing the necessary libraries, restart your development environment or terminal session for the changes to take effect. You should now be able to import modules that depend on the GObject library without encountering the “cannot load library ‘gobject-2.0-0′” error.
Additionally, if you need to use the ctypes.util.find_library() function to locate the ‘gobject-2.0-0’ library, make sure you have the correct library name. It may vary depending on your system. You can try finding the library using the following command in your terminal:
$ ldconfig -p | grep gobject-2.0
The output should display the full library name, including the version number. You can then use this name in your code as follows:
import ctypes.util
library_name = ctypes.util.find_library('')
print(library_name)
