Manim: name 'FILE_DIR' is not defined

[wlmqslch]

When I run some old_projects
I got
"name 'FILE_DIR' is not defined" in file pi_creature.py line 67
constant 'FILE_DIR' is defined in v0.1.5 and older versions (file constants.py line 29)，but it was canceled after v0.1.6.
How to solve this problem in the latest version?

From readme:

Note, however, that developments are often made to the library without considering backwards compatibility with those old projects. To run an old project with a guarantee that it will work, you will have to go back to the commit which completed that project.

The easiest solution I can see is to make a new virtualenv or conda environment and simply install older commit of manim, then run the old project with that. How to install a specific commit with pip is here, you can find the commit hash here on github after clicking on the commit.

Even in active folder I get the same error. Why this happened? I try to fix it by create a variable named FILE_DIR but can't fix it. Many script depend on this variable.
