MartinWy commented 4 years ago

If this is a support request:

Dear all

I really have done my best to solve problems and have (as a newbi) spent 4 days installing manim. Now allmost everything is fine. Except:...

When running the manim_tutorial_1 it tells me (in the last line) that the name 'Scene' ist not defined.

when I try to run python3 -m manim example_scenes.py WriteStuff -pl it gives me the following

(venv) Martins_Mac:manim37 Martin$ python3 -m manim manim_tutorial_1.py Shapes -pl Traceback (most recent call last): File "/Users/Martin/.pyenv/versions/3.7.6/lib/python3.7/runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "/Users/Martin/.pyenv/versions/3.7.6/lib/python3.7/runpy.py", line 85, in _run_code exec(code, run_globals) File "/Volumes/Daten/Animations/manim37/manim.py", line 5, in manimlib.main() File "/Volumes/Daten/Animations/manim37/manimlib/init.py", line 11, in main config = manimlib.config.get_configuration(args) File "/Volumes/Daten/Animations/manim37/manimlib/config.py", line 184, in get_configuration module = get_module(args.file) File "/Volumes/Daten/Animations/manim37/manimlib/config.py", line 179, in get_module spec.loader.exec_module(module) File "", line 728, in exec_module File "", line 219, in _call_with_frames_removed File "manim_tutorial_1.py", line 3, in class Shapes(Scene): NameError: name 'Scene' is not defined

when I try to run python3 -m manim example_scenes.py WriteStuff -pl it gives me back the following

Did you install manim with PIP? That is, using:

pip install manimlib

Or did you download the repository locally?

MartinWy commented 4 years ago

I uesd the link from the tutorial: git clone https:// github.com/3b1b/manim.git

did not use pip3 install minimlib

MartinWy commented 4 years ago

would you recommend? or not?

Elteoremadebeethoven commented 4 years ago

Since you have everything installed you should be able to run it. Try restarting your Mac and try again. If not, download this version of manim and run the same:

python3 -m manim example_scenes.py WriteStuff -pl

If it doesn't work, then install manim with PIP, but now you would run manim using:

manim example_scenes.py WriteStuff -pl

hey many thaniks. Now the problem with the missing TEX_DIR is gone. However it gives me a syntax error from manimlib.utils.tex_file_writing import tex_to_svg_file File "/Volumes/Daten/Animations/manim/manimlib/utils/tex_file_writing.py", line 59 return result

The arrow is under the n of return.

your second suggestion: install "manim with pip" pls explain further: on what level using pip 3 or pip?

and what is interesting:

before under python3 -m manim ......

the SquareToCircle ran without problem. Only the WriteStuff made problems

Now the scene definition problem comes up even in the SquaretoCircle part.
