npm ERR! cb() never called! _ when trying to install MMM-RTSPStream

[cruunnerr]

Hey guys,

i actually downgraded my MM to 2.1.0 and electron 1.4.15 cause of the “CPU Usage Problem”…
However the MM runs very well and all Modules are fluety.

Now i was trying to install the MMM-RTSPStream Module but get an error message. All other modules, where i needed to use npm install were good.

i just clone the module into my MagicMirror/modules folder and cd in the new folder. when i type in “nom install” i get the message below:

pi@MagicMirror:~ $ cd ~/MagicMirror/modules
pi@MagicMirror:~/MagicMirror/modules $ git clone https://github.com/shbatm/MMM-RTSPStream.git

Well, i am not a brilliant programmer, so i hope to get some help of you guys.

Thank you very much :)

What version of node/npm are you using? And is this on a Raspberry Pi? The commands below will tell you the versions.

node -v
npm -v

hi,

yes, its on a raspberry pi 3.

pi@MagicMirror:~ $ node -v
v6.12.2
pi@MagicMirror:~ $ npm -v
3.10.10

edit:

well, first it started to install something. i did it via ssh, so i changed to my browser to surf in the web while the raspberry is installing. When i looked back i just saw this message shown above.

You may try and update node and npm then retry:

Update npm:

npm install -g npm

Update node (should update npm too):

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

@shbatm said in npm ERR! cb() never called! _ when trying to install MMM-RTSPStream:

npm install -g npm

as i typed in this, it started to install and shows this:

so i did it as root and rebooted my pi.

now i installed your module and got some warnings AND some errors:

edit:

i took a look in the debug_log file after the reboot of the pi (2017-12-22T17_36_34_105Z-debug.log) :

could it be, that my downgrade to 2.1.0 is to blame?

[shbatm]

It may be the downgrade or a bug in the post install script for my module. Backstory: My module tries to install a patch to the main electron.js file on older MM versions so it can safely close the streams when you shut down the mirror - this is now included in the core MM code and is not installed if the code already exists.

The errors with npm upgrade: it should be sudo before that line, that’s why you have a bunch of permission errore, but the node update took care of the npm update too.

To fix the mirror install, replace MagicMirror/js/electron.js with a fresh copy from github for your version of MM to undo whatever the patch broke when it failed.
