Cannot install node-red on Ubuntu 18.04 - Even using source

Hi all

Keep it short, here is the error I got:

As you can see, I am using sudo npm install --production, but it still shows Permission denied.

node -v: v11.1.0
npm -v: 6.4.1
Ubuntu: 18.04.

Hope someone can help me.

Thank you very much in advance for your help.

The first error was because you weren't using the --unsafe-perm flag.

The second error shows you've successfully installed node-red, but you hit an error when trying to start.

The line hitting the error in particular is this one: https://github.com/node-red/node-red/blob/master/red.js#L94 where it is trying to locate your home directory.

That suggests you do not have any of HOME, HOMEPATH or USERHOME set in your environment - that is the only way an undefined would get passed to the the join call throwing an error.

I note you're using Node 11 - which we don't currently test against. I've done a quick sniff test and I see HOME is set for me when running node 11, so that won't be the root cause. There may of course be other issues with Node 11, but this isn't one.

what does echo $HOME return?

I don't know whether it is of interest but you can use the Pi bash <(curl script to install on Ubuntu. That is how I do it.

Thanks @knolleary and @Colin for the replies.

  • Under Ubuntu 18.04, echo $HOME return nothing. I have to manually set this variable in my .bashrc to run that.
  • I remember that when I first run sudo npm install -g --unsafe-perm node-red, I have this --unsafe-perm parameters. Today I run it again and it works now.

So now when I run sudo node-red, it works~

Thank you very much again for your support.

is there a specific reason you want to start Node-RED with sudo?
If not it is better practice to run without using sudo

Oh, @ukmoose, Thanks for the question.

The only reason why I use sudo node-red is that it works.

If I use node-red (without sudo), I will have the following error:

alucard@chatbot:~/chatbot/chatbot-python$ node-red
path.js:39
    throw new ERR_INVALID_ARG_TYPE('path', 'string', path);

The HOME variable I added is in my home directory: /home/alucard defined in my ~/.bashrc file, not the one from root account. Since I am not quite familiar with this config (the HOME var), when it works, I don't think too much about it. :smiley:

I understand that it is not a very good practice, but I don't quite sure what to do with it, so I leave it as it is.

Hope you can understand.

Quick update:

When I enter: nohup node-red -u /home/alucard/my_self_defined_directory &, it works nicely.

Thank you.
