"Error: stderr maxBuffer exceeded"

[ing. Carmine Manfredi]

Hi,
I tryed to install:
 

node-red-contrib-opi-gpio :

by "manage palette", but in debug there is an error:

msg : string[56]"Installation of module node-red-contrib-opi-gpio failed:"

22/1/2017, 15:27:33msg : string[42]

"------------------------------------------"

22/1/2017, 15:27:33msg : string[32]

"Error: stderr maxBuffer exceeded"

Why ?
I use:

Node-RED version: v0.16.1
Node.js  version: v6.9.4
Linux 3.4.112-sun8i arm LE

Did you also complete the pre-reqs as per the nodes documentation ?

https://www.npmjs.com/package/node-red-contrib-opi-gpio

[carmine manfredi]

No.
So I have made the group gpio from user carmine (not pi), and rebooted.
But the error is the same.

Hi,

there are two separate issues here.

1. you are hitting some error coming from npm when trying to install the node

2. the length of the error message is then causing another issue with the way we invoke npm and capture its output - "Error: stderr maxBuffer exceeded" 

I suggest you try to install the node by manually running the npm command in you .node-red directory. You will then be able to see its full output and help you get to the bottom of the issue.

I will look at the maxBuffer issue to ensure we handle that better.

They are only warnings. The final bit shows the install was successful.
