    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:

      What am I doing wrong? How shoul I install the corrsponding module for Python 3.7?

      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.

              @glestwid Your first error is:
