Why Python is so much fragile?

Python works on every machine but every time you pack some lines of code and release them in public, either through GitHub or pip, many users will stumble upon various bugs that will drive them crazy. I have basic Python knowledge but every time Im trying to install various packages from other devs I always come across at critical bugs and sometimes I rage quit. Javascript considered unstable language but I never experienced anything similar to Python (even on modules that have bindings). Based on years of system administration and testing I've done on both platforms (Linux and Windows) on the 100 modules I install in Python almost half of them fail and I have to start troubleshooting, compared to 5-10 in every 100 Javascript modules.
