+    <important>
+      <para>
+        In BLFS, we normally build and install Python 3 modules with
+        <command>pip3</command>.  Please take care that the
+        <command>pip3 install</command> commands in the book should be
+        run as &root; unless it's for a Python virtual environment.  Running
+        a <command>pip3 install</command> as a non-&root; user may seems to
+        work fine, but it will cause the installed module unaccessible by
+        other users.
+      </para>
+      <para>
+        <command>pip3 install</command> will not reinstall an already
+        installed module by default.  For using the
+        <command>pip3 install</command> command to upgrade a module (for
+        example, from meson-0.61.3 to meson-0.62.0), append
+        <parameter>-U</parameter> to the command line.  If it's really
+        necessary to downgrade a module or reinstall the same version for
+        some reason, append <parameter>--force-reinstall</parameter> to
+        the command line.
