Error message

This error happened when I use Firebase. I don't know why Realm code has problems...

error: module importing failed: Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/Users/[your_name]/Library/Application Support/Realm/rlm_lldb.py", line 37
    os.makedirs(destination, 0744)
                                ^
SyntaxError: leading zeros in decimal integer literals are not permitted; use an 0o prefix for octal integers

Solution

This is the newest code compatible with Python 3.
