[solved] Cannot install/use npm in Ubuntu 16.04 LTS

General
1

Dear all, on an older laptop, used for a lot of things, I would like to use node-red.

I tried so many things and at least I see:

$ node -v
v14.10.1

npm -v
6.14.8

but I had some warnings also,and I cannot install node red:

npm ERR! code ENOLOCAL
npm ERR! Could not install from "" as it does not contain a package.json file.

npm ERR! A complete log of this run can be found in:
npm ERR! ~/.npm/_logs/2020-09-15T19_44_58_774Z-debug.log

log content:

If I remember well, it was always mentioned that there somewhere in ?owncloud? is no release candidate..

So how can I fix this problem / I really tried a lot. what do I need to uninstall if so and how to install correctly again?

I'm willing to learn and go step by step / share with you..

What actual command did you run?

From that log it looks like you ran npm install -g - which would fail with the error you see because you haven't specified a package name to install.

To install Node-RED, you'd use npm install -g node-red

Don't you need this?
sudo npm -g install --unsafe-perm node-red

However, on Ubuntu you can normally use the recommended Debian/Ubuntu/Raspbian script to install or update node red, though I am not absolutely certain that it works with Ubuntu 16.04. https://nodered.org/docs/getting-started/raspberrypi

gives:

$ npm install -g node-red

+ node-red@1.1.3
added 17 packages from 20 contributors, removed 165 packages, updated 1 package and moved 302 packages in 14.601s

Which shows a successful installation of Node-RED 1.1.3.

There were some errors compiling the optional bcrypt dependency, but they are not fatal.

I did this:

bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)

(running)..

result:

Running Node-RED update for user rainer at /home/rainer on ubuntu


This can take 20-30 minutes on the slower Pi versions - please wait.

  Stop Node-RED                       ✔
  Remove old version of Node-RED      ✔
  Remove old version of Node.js       -
  Leave existing Node.js              -   Node v14.10.1   Npm 6.14.8
  Clean npm cache                     -
  Install Node-RED core               ✔   1.1.3 
  Move global nodes to local          ✔
  Install extra Pi nodes              -
  Npm rebuild existing nodes          -
  Add shortcut commands               ✔
  Update systemd script               ✔
                                      

Any errors will be logged to   /var/log/nodered-install.log
All done.
  You can now start Node-RED with the command  node-red-start
  or using the icon under   Menu / Programming / Node-RED
  Then point your browser to localhost:1880 or http://{your_pi_ip-address}:1880
