Hi i installed node-red version v 0.20.5 on a raspberry pi 3b+ with the latest raspbian stretch desktop  
with this command:  
bash \<(curl -sL [https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/update-nodejs-and-nodered](https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/update-nodejs-and-nodered))

When i enter to upgrade to the latest beta:  
sudo npm install -g --unsafe-perm node-red@next  
i get: sudo: npm: opdracht niet gevonden

i read that i had to specify @next, do i have to type something else, so what?

i did  
$ sudo apt-get install npm

and then i tried again  
sudo npm install -g --unsafe-perm node-red@next

npm ERR! command "/usr/bin/node" "/usr/bin/npm" "install" "-g" "--unsafe-perm" " node-red@next"  
npm ERR! cwd /usr/local/bin

npm ERR!  
npm ERR! Additional logging details can be found in:

and then again:

- the above bashscript
- sudo npm install -g --unsafe-perm node-red@next

and now it works!

It should not have been necessary to install npm using apt, it should have been installed by the script. I suggest you uninstall it and run the script again.  
Do you see any errors on the terminal?  
If not then what do these commands show

```bash
apt-cache policy nodejs
node -v
npm -v

```

Just noticed that you have recovered the situation by running the script again.
