Did you have a look at this thread and this thread on the forum?

yes but nothing changed still have the same message error

It seems to me you have somehow mixed different installation. I recommend you to remove everything and have a clean start.

I also recommend to install flair using the TAR source code.

okay sir can you help what commande should i run to install tar fil
thank you

You should go on the flair download page, scroll down to “Installation instructions”, click on “Compile from source”, and follow the instructions there.

i have this message when try to tar it

It seems that when downloading the package it was automatically unzipped.
You need to remove the “z” option when using tar:

tar xvf flair-3.1-15.1.tgz

thank you it work whtat i should do now

You should keep following the instructions.
Download the file flair-geoviewer-3.1-15.1.tgz, untar it (as you just did for the flair package), and then follow the instructions on the webpage step by step.

i have this message

It seems you’re missing tk. which is one of requirement for graphical part. Can you check?
You can find all the requirements on the page in the sections “Installation Instructions” under the “Requirements” paragraph.
You should fulfill all the requirements to successfully install flair and the geometry editor.

Have you installed the “Optionally but strongly recommended” packages indicated in the flair installation instructions?
