There are a few bugs in the update-nodejs-and-nodered installer script. These bugs arise when using the --nodered-user parameter:
This parameter sets the variable NODERED\_USER to the = part of the parameter. However the line that checks if the user is in the sudoers group does not use this variable, it uses $USER.
The line should read:
groups "$NODERED\_USER" | grep -q '\bsudo\b' && GRS="Y" || GRS="N"

Welcome to the forum @DerekK19.
I don't think it's necessary for the Node-red user to be a member of the sudo group ( **Couldn't check - see note below** ).
However it **is** necessary for the user who installs Node-red since the script calls sudo many times.
So I suspect that the line you highlight is intended to check that the **current user** is a member.
You might be right there is a bug there though, should it be like this?
```auto
groups "$USER" | grep -q '\bsudo\b' && GRS="Y" || GRS="N"
if [["$GRS" == "N"]]; then
echo "User $USER not in sudoers group. Exiting"
exit 1;
fi
```
or even
```auto
groups | grep -q '\bsudo\b' && GRS="Y" || GRS="N"
if [["$GRS" == "N"]]; then
echo "You are not in sudoers group. Exiting"
exit 1;
fi
```
**Note** I just tried installing Node-red with the --node-red-user=pi parameter and the script fell over at line 272
```auto
cd: /home/pi: Permission denied
```
and ls -l /home gives me
```auto
drwx------ 2 newuser newuser 4096 Jul 27 02:04 newuser
drwx------ 5 pi pi 4096 Jul 27 01:49 pi
```
Since neither of these users can cd to the other's $HOME, and we are strongly discouraged from running the script as root what user is able to install Node-red for someone else?
@dceejay can you comment on these two issues?

Thanks for that. To get the install to work, I added my node red user to the sudo group (very dangerous I think) and ran as that user, then didn't pass the --nodered-user parameter. Having done the install I will now remove my node red user from the sudo group - and just hope I remember all this next time I try to upgrade node-red
I think I need to read that script more fully since there is something wrong (or misleading) there

I very nearly removed my only login user (pi) from the sudo group as a test.
Not sure how I could have reversed that. 😱

First thing I do is add a second user then make that user a sudo user. Otherwise your only option is to rebuild your Pi (Been there, done that!)

Yes - you are correct - the intention is that the Node-RED user shouldn't need sudo - but he user running the install script should - so yes there do seem to be some wrinkles in there. Suggestions and/or PR would be greatly appreciated.

~~What about this though?~~
To answer my own question:
To install Node-red for a different user (on a Raspberry Pi) use the command
```auto
sudo bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --nodered-user=
```
and confirm twice that you really want to do this.

It looks like a small change is needed to the script. Just change groups "$NODERED\_USER" to groups "$USER"
Then as jbudd explains the current user would use sudo to run the script and pass the Node-Red user name as a --nodered-user parameter:

> exit 1;
> fi

Then the installing user would run:
