Hi,
On Slackware instance I am running the following command:pip install pyqt5
As a result, I get the following output with tons of errors:

Him, and welcome!
@glestwid said in "pip install pyqt5" gives tons of errors. Why?:
I get the following output with tons of errors:
When compiling any software, just focus on the first error. Once you fix that, many (or all) of the others will disappear.
The line that contains your first error is:
/usr/lib/gcc/i586-slackware-linux/5.3.0/../../../../i586-slackware-linux/bin/ld: warning: libicui18n.so.56, needed by /usr/lib/gcc/i586-slackware-linux/5.3.0/../../../libQt5Core.so, not found (try using -rpath or -rpath-link)According to that message, you must install ICU 56.

libicui18n
Ok, will libicui18n67-67.1-3-omv4002.i686.rpm work as an up-to-date substitution for 56? Should I do anything else to make 67 working as 56?

Unfortunately, I don't think ICU 67 is not backwards-compatible with ICU 56.
It looks like Slackware 14.2 (the latest stable release) contains ICU 56 but Slackware-Current (the development release) contains ICU 67.

Ok, I found missed sources for libicui, built abd deployed the lib , and now I'm getting another error while calling PIP:

I fixed the issue
"specify a working qmake or add it to PATH"by installingqton my 64-Bit Raspberry Pi OS system usingsudo apt-get install qt5-default.qmakewasn't previously on my PATH as I didn't haveQT5installed. -
the same problem I found any solution Python 3.7
