linux - CentOS - Path shows /usr/local/bin but installer shows path error

I'm trying to install heroku on a virtual machine running CentOS. When I use

curl https://cli-assets.heroku.com/install.sh | sh
I get an error message saying that my path does not include /usr/local/bin. However, when I do echo $PATH I can see /usr/local/bin.

$ echo $PATH

/usr/local/bin:/local/home/sysadmin/.rbenv/plugins/ruby-build/bin:/local/home/sysadmin/.rbenv/shims:/local/home/sysadmin/.rbenv/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/local/home/sysadmin/.local/bin:/local/home/sysadmin/bin

What should I do to fix this?

Answer

That script requires root to install.
That means that when the script is running, it will be using root's environment and not yours. Root probably doesn't have /usr/local/bin in the path.

I am giving you the likely quick fix. This fix assumes that you have root permissions.. otherwise, you couldn't run this script in the first place.

The following suggestion will quite possibly make some *nix people crazy (because of sudo -i).

Open a terminal:

sudo -i                             #-- this logs you in as root.
export PATH=$PATH:/usr/local/bin    #-- temporarily add the path you need

exit                                #-- DONT run anything else as root!

Good luck..
