I just went through the steps of installing Electrum from electrum.org (see "Installation from Python sources" at
https://electrum.org/#download). Everything seemed to go smoothly until I got to the last line:
python3 -m pip install --user Electrum-4.1.5.tar.gz
After I entered this command I got the following messages as part of the response in Terminal:
WARNING: The script helpdev is installed in '/home/USERNAME/.local/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
WARNING: The script qdarkstyle is installed in '/home/USERNAME/.local/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
WARNING: The script qr is installed in '/home/USERNAME/.local/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --now-warn-script-location.
(Note: I changed my username to "USERNAME" for the purposes of this forum.) The text for these messages was orange, rather than white, so I take it that means these messages were important (I'm a noob). There was more text, but that's everything that was orange. I did not notice any other orange text when I scrolled through all the text in Terminal. After these warning messages, it returned, "Successfully installed Electrum-4.1.5," etc.
I did enter every line -- sequentially -- listed under "Installation from Python sources," so I'm not sure why this installation failed. Electrum even seemed to load and work when I entered the two lines for "Run without installing."
Note that when I say the installation failed, I mean the application doesn't seem to exist in my computer's list of applications.
Help is much appreciated.
