Linux export - installation of Screenplain fails #10

Hi, tested the export but there is an error about the module screenplain: Tested in 2.81 ( GNU/Linux)

i tried to look the code,maybe the problem is that the Linux path is " / " and not " \ " so the screenplain module is not installed correctly: Referred to Blender_Screenwriter.py line 542: home_url = bpy.utils.script_path_user() + "\\addons\\"

tin2tin commented 5 years ago

Let me know if that solves it on Linux?

AndreaMonzini commented 5 years ago

i changed home_url = bpy.utils.script_path_user() + "\\addons\\" to home_url = bpy.utils.script_path_user() + "//addons//"

But same errors. I cannot find Screenplain as downloaded or installed If i manually download screenplain-0.8.0.zip and copy the screenplain folder in the addon folder i have this error:

tin2tin commented 5 years ago

I don't know anything about Linux, but you probably do not have to use double // when they are turning that way.

Copying it to the add-on folder is what the add-on does and it works on Windows. Well actually it's the same way fountain.py is used by the add-on.

Have you tried to Google that error? (I'm not at my computer right now)

tin2tin commented 5 years ago

A moment at the computer. Seems like you're missing a module called six.

It can be installed using these instructions, but of course installing six instead pycodestyle: https://github.com/tin2tin/Python_Stylechecker_for_Blender

For reference: https://pypi.org/project/six/

AndreaMonzini commented 5 years ago

I was able to install pip and six, thank you. But still not work, probably i have to check the right path for the installation. Now is in pip3 install six Requirement already satisfied: six in /usr/lib/python3/dist-packages (1.12.0)

i checked in library and i have installed Python 2.7, 3, 3.7 and 3.8. i need to investigate more.

tin2tin commented 5 years ago

It is using the Python which comes with Blender. So you must run the pip command in the console in the Blender Python folder: image

Screenplain can also be installed this way, but I would be happy if you could find a way to get the BSW to do it on Linux.

tin2tin commented 5 years ago

Does the add-on work if you install screenplain with pip?

AndreaMonzini commented 5 years ago

I installed screenplain with pip Requirement already satisfied: six in /usr/lib/python3/dist-packages (from screenplain) (1.12.0) Installing collected packages: screenplain Successfully installed screenplain-0.8.0 but still far for working

tin2tin commented 5 years ago

And installed from the Blender Python bin?

AndreaMonzini commented 5 years ago

I am searching to installing it using Blender Python console, but in Linux is a bit different. i do not have a Python.exe in the blender Python folder so i am trying to run it with ./

Blender Pyhton does not recognise pip or pip3:

tin2tin commented 5 years ago

Ah, try to download and place this file in the folder with the Blender python exe: https://bootstrap.pypa.io/get-pip.py

And then run it from the command line with python "get-pip.py"

Or else try the ensurepip etc. stuff from here: https://blender.stackexchange.com/questions/108283/how-to-load-external-modules-packages-into-blender-python/140343#140343

AndreaMonzini commented 5 years ago

I just enabled ensurepip

tin2tin commented 5 years ago

Bingo! If you want to test the pdf output, you can search for pdf and find some commented out code in Blender_Screenwriter.py which just needs to be inserted to get it to become an export option. I suspect that it is also module related.

Could you do me a favour at use pip to uninstall screenplain again, and then try to install it with BSW.py and see it it succeds now? (Then you can install screenplain again afterwards)

AndreaMonzini commented 5 years ago

Sure now is uninstalled. linux@pop-os:~$ '/home/linux/App/blender-2.81-0a0d735acd6e-linux-glibc217-x86_64/2.81/python/bin/python3.7m' -m pip uninstall screenplain Uninstalling screenplain-0.8.0: Would remove: /home/linux/.local/bin/screenplain /home/linux/.local/lib/python3.7/site-packages/screenplain-0.8.0.dist-info/* /home/linux/.local/lib/python3.7/site-packages/screenplain/* Proceed (y/n)? y Successfully uninstalled screenplain-0.8.0

But this the error when i try to export:

tin2tin commented 5 years ago

So it is not looking in the addons folder for the screenplain files? But properly where it was installed with pip.

Hmmm... I hope we can find better way than using pip in the console, but if not, could you write how to do it on Linux, so we can put in on the main page?

AndreaMonzini commented 5 years ago

I un-commented the PDF, saved, restarted blender, export but i do not see PDF export options:

export

AndreaMonzini commented 5 years ago

To install screenplain using GNU/Linux with Blender Python i used 2 commands with the terminal: 1: '/INSTALLED_BLENDER_PATH/2.81/python/bin/python3.7m' -m ensurepip 2: '/INSTALLED_BLENDER_PATH/2.81/python/bin/python3.7m' -m pip install screenplain

tin2tin commented 5 years ago

You need to place the (pdf etc.) inbetween the html and the fdx stuff. in the following line.

NB. You'll need to install a different version of screenplain for pdf: https://github.com/vilcans/screenplain (which installs additional modules)

iirc is that the same error I'm getting. Can you get pdf conversion to work using the command line(I couldn't)?

ok i exported to pdf from command line after installing screenplain in /usr/local/bin

i found similar error: https://github.com/vilcans/screenplain/issues/47

tin2tin commented 5 years ago

For reference on installing using PIP: https://developer.blender.org/T71420 Maybe Jacques' solution can be used for installing external modules like Screenplain, instead of the current solution which apparently fails on Linux?

AndreaMonzini commented 5 years ago

I think that Jacques' solution could be very useful, i hope it is compatible with text editor too. Anyway i am using VSCodium when necessary:

This may have been fixed, but I'm not on Linux, so I can't test. Can anyone help me with this?
