Why Isn't Manage palette Showing up

General
1

I am trying to install nodes and when I open node-red the log says that npm could not be found

2

open a terminal window.

Enter the following commands and show what you see...

  • npm -v
  • node -v

PS: as the text says, you need NPM installed to use the library. Also, this has been covered many times on the forum (do a search)

3

For my node version I have v12.16.3 and for my npm version I have 6.14.4

4

Odd - that version of NPM is sufficient.

How are you running node red (what command line do you use / how do you launch it)

Is it a direct install or docker?

what OS are you running on

also, post a copy of the terminal startup log (as text (not screenshot) if possible)

5

It is a direct install I am using windows and the line I am using is node-red

6

copy and paste the text that appears after entering node-red please

Paste it ...

```
like this - between three backticks (for formatting and readability purposes
```

---------------------------------------------------------------------
Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

I think npm is not on the system path.

Add the directory of npm into system env vars

That is most likely the answer I just need to look to where the path is

11

This is where the folder npm is C:\Program Files\nodejs\node_modules\npm OI do not know if this is true or I am looking at the wrong file

12

what do you get if you enter where npm in a cmd window?

13

I get Nothing when I put where npm

14

sorry typo. try which npm

15

Which Give me an error saying that it isn't a command

16

then your'e gonna have to search you computer to find NPM.

Its likely to be in C:\Program Files\nodejs\node_modules\npm\bin - have a look see if npm.cmd is there.

When you find the path, add it to the system path, restart the CMD window, type path to check its present then run node-red.

17

now node red will not start

18

Did you add or change path?

Edit...

Potentially, node red wasn't in your system path either (and your command window was on the right path to start it)

Basically speaking - the application your are trying to start MUST be on the current path OR in user PATH or SYSTEM PATH.

For node-red to work properly, 3 elements have to be reachable...

  • Node
  • npm
  • Node-red
19

ok I will try to make it work

20

What if I uninstall and reinstall Node.Js and Node-Red and see if I can run it again?

21

Possibly but a bit overkill.

Better off fixing it then you'd learn something. But if you must...
