Multiple PlatformIO Cores in a system¶
Multiple standalone PlatformIO Core (CLI) in a system could lead to the different issues. We highly recommend to keep one instance of PlatformIO Core or use built-in PlatformIO Core in PlatformIO IDE:
PlatformIO IDE for Atom -
Menu PlatformIO: Settings > PlatformIO IDE > Use built-in PlatformIO Core
Finally, if you have a standalone PlatformIO Core (CLI) in a system, please open system Terminal (not PlatformIO IDE Terminal) and uninstall obsolete PlatformIO Core:
pip uninstall platformio # if you used macOS "brew" brew uninstall platformio
‘platformio’ is not recognized as an internal or external command¶
If you use PlatformIO IDE, please check in PlatformIO IDE Settings that “Use built-in PlatformIO Core” is enabled.
If you modify the system environment variable
PATH in your Bash/Fish/ZSH
profile, please do not override global
PATH. This line
export PATH="/my/custom/path" is incorrect. Use
ImportError: cannot import name _remove_dead_weakref¶
Windows users can experience this issue when multiple Python interpreters are installed in a system and conflict with each other. The easy way to fix this problem is uninstalling all Python interpreters using Windows Programs Manager and installing them manually again.
“Windows > Start Menu > Settings > System > Apps & Features”, select Python interpreters and uninstall them.
Install the latest Python interpreter, see Install Python Interpreter guide
C:\.platformiofolders if exist (do not forget to replace “YourUserName” with the real user name)
Restart PlatformIO IDE.
