TypeError: a bytes-like object is required, not 'str'

[JacobPimental]

I'm trying to use r2pipe in Python 3 and keep running into the error "TypeError: a bytes-like object is required, not 'str'" when using the cmd() function. I have updated r2pipe via pip3, updated r2 to the latest version, and even updated r2pm just in case that would help any. I am running this on a Manjaro Linux machine, though I'm not sure if that would cause any problems. Here is the exact error I am getting:

Traceback (most recent call last):

os.write(self.pipe[1], cmd)

There are some places to change, e.g.:

         def _cmd_pipe(self, cmd):
-                out = ''
+                out = b''
                 cmd = cmd.strip().replace("\n", ";")
                 if os.name == "nt":

It looks like the r2pipe in pypi is the 2.4.0 release of this repo, but the current HEAD version changed a lot. I think you can modify the py files in your installed files.

This is the fix for 2.4.0 (looks like it's the current r2pipe-0.9.9)
