[reliveinfire]

Hi community, i use the mingw64 env, the ipython3 not working, i got the message

pm3 ~/proxmark3/client/experimental_lib/example_py$ ipython
Python path configuration:
  PYTHONHOME = '/mingw64'
  PYTHONPATH = (not set)
  program name = 'E:/proxmark/ProxSpace/msys2/mingw64/bin/python.exe'
  isolated = 0
  environment = 1
  user site = 1
  import site = 1
  sys._base_executable = 'E:/proxmark/ProxSpace/msys2/mingw64/bin/python.exe'
  sys.base_prefix = '/mingw64'
  sys.base_exec_prefix = '/mingw64'
  sys.platlibdir = 'lib'
  sys.executable = 'E:/proxmark/ProxSpace/msys2/mingw64/bin/python.exe'
  sys.prefix = '/mingw64'
  sys.exec_prefix = '/mingw64'
  sys.path = [
    '/mingw64/lib/python39.zip',
    '/mingw64/lib/python3.9',
    '',
  ]
Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
ModuleNotFoundError: No module named 'encodings'

i tried to solve this with venv from google

(venv) pm3 ~/proxmark3/client/experimental_lib/example_py$ source venv/bin/activate
(venv) pm3 ~/proxmark3/client/experimental_lib/example_py$ sh 02run_test_grab_interactive.sh

     14 else:

     16
     17 try:

ModuleNotFoundError: No module named '_pm3'

In [1]: exit

and it can not find the _pm3, is there anything wrong about the ipython config in the branch?

thanks
