[BlenderBIM] installation problem

  1. N by Nigel on 12 Feb 2023, edited 13 Feb 2023 #

    I have been struggling to get Blender BIM to install. When i 'tick the box' to enable I get the following Traceback... I know it's me :) Some insight into why it's me will be really appreciated.

    Traceback (most recent call last):

    File "C:\Users\nigel\AppData\Roaming\Blender Foundation\Blender\3.4\scripts\modules\requests\compat.py", line 11, in <module>

    import chardet

    ModuleNotFoundError: No module named 'chardet'

    During handling of the above exception, another exception occurred:

    ModuleNotFoundError: No module named 'chardet'

    Seems to be this module after googling:

    https://pypi.org/project/chardet/

    That is odd because BlenderBIM works for me without this module, I also don't have it installed.

    Maybe some other add-on is causing it?

    Atleast what you could try is trying to install the chardet add-on from Blender and see if the message dissappears

    
import sys

import subprocess

py_exec = str(sys.executable)


# ensure pip is installed

#subprocess.call([py_exec, "-m", "pip uninstall pip", "--user" ])

#subprocess.call([py_exec, "-m", "ensurepip", "--user" ])

#subprocess.call([py_exec, "-m", "pip install -U pip", "--user" ])

# update pip (not mandatory but highly recommended)

#subprocess.call([py_exec, "-m", "pip", "install", "--upgrade", "pip" ])


# install packages

subprocess.call([py_exec,"-m", "pip", "install", f"--target={py_exec[:-14]}" + "lib", "chardet"])

    Or try disabling all other add-ons and see if the message dissapears

    @Coen thank you for your help, alas to no avail. It is doing my head in, I have disabled all Addons, reinstalled Blender. Now lost for clues :(

    @Coen OMG I'm such a dummy, I needed to run Blender as an administrator and your code worked, BlenderBIM enabled successfully. Thank you. I'll write that on a post note and stick on my monitor :)
