ImportError: cannot import name 'VERSION' from 'serial' (unknown location)

[dichaos]

hello,

I installed the latest version of pyftdi via pip. I upgrades all of my packages to the latest version too but when I try to load pyftdi.serialext I get the error message

Traceback (most recent call last):
File "/usr/local/lib/python3.9/site-packages/pyftdi/serialext/init.py", line 15, in
from serial import VERSION, serial_for_url as serial4url
ImportError: cannot import name 'VERSION' from 'serial' (unknown location)

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "/Users/dikaios.papadogkonas/Desktop/lidar.py", line 7, in
import pyftdi.serialext
File "/usr/local/lib/python3.9/site-packages/pyftdi/serialext/init.py", line 20, in
raise ImportError("pyserial 3.0+ is required") from exc
ImportError: pyserial 3.0+ is required

I have installed pyserial 3.5

Any idea why it can't find VERSION ?

Weird.

serial.VERSION is define here:

https://github.com/pyserial/pyserial/blob/0e7634747568547b8a7f9fd0c48ed74f16af4b23/serial/__init__.py#L20

Maybe try to use Python REPL and check which file is actually imported:

>>> import serial
>>> print serial.__file__

and check the actual content of this file.

Thank you for your reply, interesting, I get "None"

Should be something like:

> python3
Python 3.8.6 (default, Nov 21 2020, 23:20:31)
[Clang 12.0.0 (clang-1200.0.32.27)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import serial
>>> serial.VERSION
'3.5'
>>> serial.__file__
'/usr/local/lib/python3.8/site-packages/serial/__init__.py'

Try uninstalling pyserial and check that import serial fails with an ImportError.

Bw sure you do no have a serial.py somewhere in your PYTHONPATH that could be imported instead of pyserial's.

Actually uninstalling and re-installing fixed it. Sorry about that and thank you
