@apollon77 Ich glaube sogar dass das gar kein Problem ist. Der Ordner gehört nunmal nicht pi, also darf er auch keine Rechte ändern. Deswegen hab ich ja auch den Aufruf von chmod entfernt:
https://github.com/ioBroker/ioBroker.js-controller/pull/379

@apollon77
Probier es gerne aus, was muss ich tun?

Momentan scheint aber alles ohne Probleme zu laufen.

[apollon77]

@southparkler alles gut. Wenn’s geht ist ok.

Hallo,
ich möchte mein Multihost-System upgraden.
Master: Ubuntu Server

Platform: linux
Architecture: x64
Node.js: v8.16.0
NPM: 6.4.1

Slave: Raspberry Pi 2

Platform: linux
Architecture: arm
Model: ARMv7 Processor rev 5 (v7l)
Node.js: v6.14.2
NPM: v3.10.10

Upgrade des Master war kein Problem.
Aber beim Slave bekomme ich diese Meldung:

Used repository: default
Json file is invalid on http://download.iobroker.net/sources-dist.json
update done

Jetzt will ich mir nichts zerschießen und wüsste gerne, woran diese Meldung liegt und ob sie kritisch ist?

Danke für jeden guten Hinweis :-)

[apollon77]

@piForscher welche js-Controller Version hat der Slave?

[piForscher]

@apollon77 : Der Slave hat die 1.4.2

[apollon77]

@piForscher sagte in [Diskussion] js-controller 1.5.11 ab sofort im Stable Repository:

http://download.iobroker.net/sources-dist.json

Also bei mir ist das File valide. mach doch mal "iobroker upgrade self" auf dem slave

[piForscher]

@apollon77

sudo iobroker upgrade self
Cannot find this controller "js-controller" in repository.

???

[apollon77]

Sehr strange. Kannst Du das File (http://download.iobroker.net/sources-dist.json) normal per Browser oder "wget" runterladen?

Im Notfall mach es auf die Harte tour:

npm install iobroker.js-controller --production

im iobroker Verzeichnis

Problem erkannt: Es gab keine Internetverbindung...
Sorry, da hätte ich auch schneller drauf kommen können.
Jetzt hat alles geklappt!
@apollon77 Vielen Dank für deine Hilfe!

Nur zur Info:

Hatte jetzt öfters diverse Logeinträge bei verschiedenen Adaptern. Nach dem Installation Fixer sind diese bisher nicht mehr aufgetreten.

Hallo zusammen,

js-controller lässt sich nicht updaten.
habe gesehen, dass node, nodejs sind auch nicht aktuell.

danke im Voraus.

[apollon77]

Also in bezug auf diesen Thread hast du durch die Neuinstallation schon den aktuellsten js-Controller. Das du irgendwiezwei verschiedene nodejs Versionen hast ist ein anderes Thema. Such mal danach im Forum. Bin gerade nur auf dem Handy.

[Conquest]

Hallo ich bekomme leider den neuen js-controller nicht installiert.

torsten@iobrokerserver-VirtualBox:~$ node -v
v8.16.0
torsten@iobrokerserver-VirtualBox:~$ nodejs -v
v8.16.0
torsten@iobrokerserver-VirtualBox:~$ npm -v
6.4.1

Update js-controller from @1.4.2 to @1.5.11
NPM version: 6.4.1
npm install iobroker.js-controller@1.5.11 --unsafe-perm --production --save --prefix "/opt/iobroker" (System call)
Unhandled rejection Error: EACCES: permission denied, open '/home/torsten/.npm/_cacache/tmp/deb77656'

Vielleicht kann mir jemand weiterhelfen?

[apollon77]

@Conquest sagte in [Diskussion] js-controller 1.5.11 ab sofort im Stable Repository:

npm ERR! cb() never called!

Installation Fixer mal laufen gehabt?

[Conquest]

@apollon77 Hat funktioniert danke.
Das komische ist nur das ich den Installations-Fixer schon mal gemacht hatte.

[bergjet]

Ich habe den js-controller 1.5.12
npm 6.9.0
node 10.16.0
NodeJS 8.16.0

Wie bekomme ich Node und NodeJS auf den selben Stand?

[Stabilostick]

Der js-controller 1.5.14 ist jetzt im latest-Repository. Siehe https://forum.iobroker.net/post/282544

[Stabilostick]

@bergjet

Mehrere Node.js löschen:

sudo apt-get purge node
sudo apt-get purge nodejs
sudo apt-get purge npm
sudo apt-get autoremove
sudo reboot

Anschließend nach der Anmeldung

ls -l /usr/local/bin/node*
ls -l /usr/bin/node*

Und danach Node.js 10 nach Anleitung installieren.
