Setting up environment on UNIX and LINUX

EASIFEM cli (recommended method)

The easiest way to work with the EASIFEM is easifem command line interface.

  • First download the easifem from pip by using following command.
pip install easifem
  • Then, we can set up the environment variables by using following command.
easifem setenv --install /home/easifem/install --build /home/easifem/build --source /home/easifem/src
  • This command will create config files for bash, zsh, and fish shell in ~/.config/easifem directory. For bash and zsh the name of the file is easifemvar.sh, and for fish the name of the file is easifemvar.fish.
  • Then, you can run following command to bring the changes in your current shell session.
source ${HOME}/.config/easifem/easifemvar.sh
source $HOME/.config/easifem/easifemvar.fish

:::info

  • If you are using bash or zsh shell, then you can place easifemvar.sh in your shell. For bash or zsh shell, open .bashrc or .zshrc in your editor and add the following line at the end of the file:
source ${HOME}/.config/easifem/easifemvar.sh
  • If you are using fish shell, then you can place easifemvar.fish in your shell. For fish shell, open config.fish in your editor and add the following line at the end of the file:
source $HOME/.config/easifem/easifemvar.fish

import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem';

The following file is generated by running the command.

easifem setenv --install /home/easifem/.easifem --build /home/easifem/temp --source /home/easifem/temp/src
    export EASIFEM_INSTALL_DIR=/home/easifem/.easifem
