Micropython plugin (MQTT) installation fails

Hello,

I was using PyCharm 2022 with the micropython plugin to work with an ESP8266 - all worked fine.

With PyCharm 2025 I switched to the “Micropython Tools” and now I'm not able to install certain Micropython plugins, like “micropython-umqtt-robust”. 

I'm getting:

ERROR: Invalid member in the tar file 
..\Temp\pip-unpack-7vnwtgob\micropython-umqtt.robust-1.0.tar.gz: 'umqtt/simple.py' would link to '..\\Temp\\pip-install-ajfwrhz2\\umqtt.simple\\umqtt\\simple.py', which is outside the destination

I've no idea how to deal with this. But first starting the installation of “simple.py”, leads to an error, as well:
ERROR: micropython-umqtt-simple from ../micropython-umqtt.simple-1.3.4.tar.gz does not appear to be a Python project: neither 'setup.py' nor 'pyproject.toml' found.

I also tried to manually install directly to the ESP using "mip.install", which ended with "OSerror: -2" - whatever that means…

I'm running out of ideas. Any suggestions?

Many thanks.

T Electronics, have you tried installing the package from the system terminal (outside the IDE) using the same virtual environment?

  • If it fails with the same error in the terminal, then the issue is most likely not related to PyCharm
  • If it works in the terminal but fails only inside PyCharm, please create a YouTrack issue here: https://youtrack.jetbrains.com/issues/PY

When submitting the report, please attach any relevant details (error output, your PyCharm version, interpreter information, and ideally IDE logs from Help | Collect Logs and Diagnostic Data right after reproducing the issue). This will help us investigate more efficiently.

Hi, 
many thanks for your answer. I'm not sure what your are referring to exactly with “installing the package from the system terminal (outside the IDE)”.
I did try mip.install via the terminal of PyCharm (received OSerror: -2). So, not 100% outside PyCharm, but via terminal. Shall I use another terminal or rather submit a ticket right away?

Thank you!

T Electronics, does the same behavior occur when you run it from a system terminal (Windows Terminal / PowerShell / xterm / macOS Terminal, depending on your system) using the same virtual environment, with PyCharm completely closed? If so, could you please share the full error message/output you see there?
