问题：
Before installing gnuplot, I set the environment variable GNUPLOT_DRIVER_DIR = /home/gnuplot/build/src . 在安装gnuplot之前，我设置了环境变量GNUPLOT_DRIVER_DIR = /home/gnuplot/build/src 。 During the installation, something went wrong. 在安装过程中出现了问题。
I want to remove the GNUPLOT_DRIVER_DIR environment variable. 我想删除GNUPLOT_DRIVER_DIR环境变量。 How can I achieve it? 我怎样才能实现它？
