Recently, I migrated to the NixOs and installed PlatformIO core on it. Here is the output of the upload command:
Code: 
pio run -t upload

Opening Teensy Loader...
Unable find Teensy Loader.  (p)  Is the Teensy Loader application running?
quitscons: *** [upload] Error 1

I can find the teensy_loader_cli in platformio directory:
Code: 
ls ~/.platformio/packages/tool-teensy/
00-teensy.rules  mktinyfat          stdout_redirect  teensy_gateway         teensy_post_compile  teensy_serialmon
lib              package.json       T4Security.jar   teensy_loader_cli      teensy_reboot        teensy_size
libpng12.so.0    precompile_helper  teensy           teensy_loader_cli_bin  teensy_restart
libusb-0.1.so.4  pre_uninstall.sh   teensy_cleanup   teensy_ports           teensy_secure

Installing packages like teensy-udev-rules and teensy-loader-cli did not help.
Could you help me to know how should I fix this issue?
 
Thanks for the answer, it seems adding that line solved that issue. But now it can not find the libudev.so.1
Code: 
AVAILABLE: jlink, teensy-cli, teensy-gui
CURRENT: upload_protocol = teensy-cli
Rebooting...
teensy_reboot: error while loading shared libraries: libudev.so.1: cannot open shared object file: No such file or directory
*** [upload] Error 127

I think I need to find the correct path and add it to LD_LIBRARY_PATH which I guess is an issue that I should follow in the NixOs community.
