Radian does not start on Big Sur 11.2

[MikhailArkhipov]

1. MacOS Big Sur 11.2 on M1, brand new clean laptop
2. R 4.0.3 installed from https://cran.r-project.org/bin/macosx/
3. Python 3.9.1 installed via python.org installer with universal binaries
4. Radian installed via pip3

• R.app runs normally
• Attempt to start radian fails with

  Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/bin/radian", line 33, in <module>
  sys.exit(load_entry_point('radian==0.5.10', 'console_scripts', 'radian')())
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/radian/__init__.py", line 44, in main
  r_home = Rhome()
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/rchitect/utils.py", line 69, in Rhome
  raise RuntimeError("R_HOME ({}) does not exist.".format(rhome))
  RuntimeError: R_HOME (/usr/local/lib/R) does not exist.

  /usr/local/lib/R indeed does not exist on MacOS 11.2 R is in /Library/Frameworks/R.framework/Versions/Current

Attempt to set

env R_HOME=/Library/Frameworks/R.framework/Versions/Current radian

then fails with

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/bin/radian", line 33, in <module>

    raise Exception(load_lib_error())
Exception: Cannot load shared library: dlopen(/Library/Frameworks/R.framework/Versions/Current/lib/libR.dylib, 10): image not found

since library is in /Library/Frameworks/R.framework/Versions/4.0/Resources/lib/libR.dylib

The only thing that works is setting

R_HOME=/Library/Frameworks/R.framework/Versions/Current/Resources radian

R_HOME=/Library/Frameworks/R.framework/Versions/Current/Resources radian This didn't work for me. Are there any other ways that worked?

Only thing that worked for me was building R from source (with homebrew) to ensure its M1 native and not through Rosetta.
