Or create conda environments (install Anaconda).
What's the difference between the two (virtualenv and conda), and do you have a link to a decent guide for someone who has no experience with them?

Re: Cannot erase flash, ESP32

ah ok, ill try that.
what i meant by the "not the .py" version of the esptool, is that i installed it from the standard ubuntu repos, not using pip. it was there and installed it by running `sudo apt install esptool`.
