flavored distro. Anyone can report what version and linux distro they are using where NanoVNA-saver works right away? I am willing to change distro if it comes that that. Pierre VE2PF Le jeu. 16 janv. 2020 ¨¤ 10:37, Nick <g3vnc@...> a ¨¦crit :

I'm a little confused as to the decision on the Linux Mint packagers toYes, we might even have got a newer version of python-pip3 - see below. Anyway, getting near to the bottom of this now. Following notes apply to LM19.3. As I understand it $ python3.7 -m pip install . parses ~/nanovna-saver/requirements.txt and installs the latest versions of the required python distribution packages if they are not already installed i.e. scipy pyqt5 pyserial numpy pip will always install the latest versions, not whatever (older) versions happen to be available from the distro package management system - which is good. Since 15.12.19 when I installed nanovna-saver-0.2.2a there have been two new versions of PyQt5... The installation error reported arises when pip3 attempts to install PyQt5==5.14.1. We are not alone... The pip3 version provided with the distro package python3-pip appears to be too old. $ pip3 -V pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6) Having read more about it seems that using sudo with pip3 to overcome the error (as suggested in my earlier post #9634 and elsewhere) is a bad idea; if you need to use sudo you are probably trying to modify a distro file. There is no easy way to upgrade the version of pip3 supplied by the distro package python3-pip. If the package manager advertises a new version then you can install that as an update. It's a distro file and you shouldn't try to upgrade it any other way. I managed to break (and fix) pip3 several times in the attempt. One way round this problem would be to install nanovna-saver in a python virtual environment. Another way is to modify ~/nanovna-saver/requirements.txt... scipy pyqt5==5.13.2 pyserial numpy then from ~/nanovna-saver/ $ python3.7 -m pip install -r ./requirements.txt . This installs PyQt5==5.13.2 which is the version I used on 15.12.19. I have tested this and it seems to work properly. I do not understand why I had to explicitly specify the path to requirements.txt though. Nick |
Re: Connectors on RF Test Board leads
I bought one also and I cannot connect the cables either.
Nice concept, but if it doesn't work, what good is it.

NanoVNA-Saver does *not* use any image files in a zip-file - you must be thinking about NanoVNASharp, or one of the varieties. -- Rune / 5Q5R On Thu, 16 Jan 2020 at 14:58, Leif M <sala.nimi@...> wrote:

Note too that on Debian derived systems you need to specify python major version when you apt libraries.? e.g., "apt install python-numpy" gets for v2.? "apt install python3-numpy" gets for v3.

Hi Graeme,

you can definitely install Python 3.7 next to Python 3.6, if your OS requires it. I'm a little confused as to the decision on the Linux Mint packagers to release 19.3 late last year with Python 3.6, when 3.7 was already more than 18 months old, and 3.8 had just been released as well. Going with a version that old is bound to cause problems for the users. -- Rune / 5Q5R On Thu, 16 Jan 2020 at 01:13, Graeme Jury <gvjury@...> wrote:

I can't simply unload python 3.6 and upgrade to python 3.7 ???? You don't have to, you can have both 3.6 and 3.7 installed. 3.6 remains the default for the Mint applications, and when you want to start something that requires 3.7, you simply preface it with python3.7, like so:? "python3.7 nanovna-saver.py."??

Re: Installing NanoVna-Saver : First Time Problems/Fixes
I install again the SP and VC++ but still receive the same error.
At the first try, I installed previously the "api-ms-win-core-xxx.dll" separately because I had error that they were missing. Step by step, I was able to go further in the install process. I try to remove one of those dll with the identical result. Install it again let me go further. After new install SP and VC++, I'm still having "nanovna saver has top working" at the end of the installation. Any idea how to solve ? PS: I install successfully on my Win 10. Yves |
