import pyte
from winpty import PtyProcess
try:
    print('hihi')
    PtyProcess.spawn('pnpm -v')
except Exception as e:
    print('oo')
    print(e)
print('ha')
import os
print(os.environ.get('pa_th','2'))

there are 3 points:
1,command not found when ptyprocess spawning
2,os.environ.get is called with default value
3,this env variable doesn't exist actually

current behavior:
program blocked on "os.environ.get"
