Getting error while trying to run this command " pipenv install requests " in mac OS

What worked for me on Mac OS X Sierra is adding the following into my ~/.bash_profile file:

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"

Then I reloaded the bash profile with: source ~/.bash_profile

For those who use zsh shell, you must add those lines to your ~/.zshrc

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"

Then I reload the bash profile with: source ~/.zshrc

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
