|
|
|
The dependencies `Ghostscript <https://www.ghostscript.com>`_ and `Tkinter <https://wiki.python.org/moin/TkInter>`_ can be installed using your system's package manager or by running their installer.
|
|

Checks to see if dependencies are installed correctly
|
|
-----------------------------------------------------
|
|
|
|
You can run the following checks to see if the dependencies were installed correctly.
|
|
|
|
For Ghostscript
|
|
^^^^^^^^^^^^^^^
|
|
|
|
Open the Python REPL and run the following:
|
|
|
|
For Ubuntu/MacOS::
|
|
|
|
>>> from ctypes.util import find_library
|
|
>>> find_library("gs")
|
|
"libgs.so.9"
|
|
|
|
For Windows::
|
|
|
|
>>> import ctypes
|
|
>>> from ctypes.util import find_library
|
|
>>> find_library("".join(("gsdll", str(ctypes.sizeof(ctypes.c_voidp) * 8), ".dll")))
|
|
<name-of-ghostscript-library-on-windows>
|
|
|
|
**Check:** The output of the ``find_library`` function should not be empty.
|
|
|
|
If the output is empty, then it's possible that the Ghostscript library is not available one of the ``LD_LIBRARY_PATH``/``DYLD_LIBRARY_PATH``/``PATH`` variables depending on your operating system. In this case, you may have to modify one of those path variables.
|
|
|
|
For Tkinter
|
|
^^^^^^^^^^^
|
|
|
|
Launch Python and then import Tkinter::
|
|
|
|
>>> import tkinter
|
|
|
|
**Check:** Importing ``tkinter`` should not raise an import error.
