ERRO: Environment variable GUROBI_HOME is not set.

[Guido Pantuza - Miziphi]

Hi, I am installing gurobi 6.5.1 on ubuntu 14.04 LTS on an academic license. When I try to run any gurobi command i got the error: command not found or Environment variable GUROBI_HOME is not set.

I have followed the user guide steps to set the environment variables. The license is ok.

Did you open a new terminal after updating your .bashrc file according to the instructions at https://www.gurobi.com/documentation/6.5/quickstart_linux/software_installation_guid.html? If not, please try this so that the exports can take effect. If you did, please post the results of the following commands:

  echo $GUROBI_HOME

  ls $GUROBI_HOME

Dear Garcia, when i open a new terminal, if i use the command  echo $GUROBI_HOME thres no answer, just a empty line, if i use ls $GUROBI_HOME just appears the files and folders of the current folder.

If i set the variables, using the command "export" and then use the  command  echo $GUROBI_HOME, i get the right path and i can use the gurobi (this is valid for the other variables). But after close the terminal, the variables loss hers path, and i need to set all again.

Thank you for your help.

As stated in the instructions at https://www.gurobi.com/documentation/6.5/quickstart_linux/software_installation_guid.html, you can place the export commands inside a file named '.bashrc' in your home directory so that the exports persist across different terminal sessions. The commands in this file are executed each time you open a terminal. This is a basic Linux concept which is not specific to Gurobi, so you can Google 'bashrc file' if you need more guidance on how to set one up.
