NPM (node.js Package manager) can't install tiddlywiki

Question

first post at the forum, hopefully with enough details for you to give me a hand ;-)

I'm trying to get "tiddlywiki" (a note taking JavaSkript Application) running on my Synology DS 220 via node.js used following official tutorial: https://tiddlywiki.com/static/Installing%2520TiddlyWiki%2520on%2520Node.js.html

npm install -g tiddlywiki

and also

sudo npm install -g tiddlywiki

so far I'm getting only ERR (via SSH and admin):

rollbackFail... etc ERR ... EAI_AGAIN...

log containes following:

what i also was trying:

npm install (for update, no reaction/new version...)

npm config rm proxy npm config rm https-proxy

then this npm config set registry https://registry.npmjs.org/ >also npm config set strict-ssl false

...so everything I could find here or on the internet

my setup:

• I use the onboard encryption for the home-folder ...obviously starting the install process only when folder is decrypted

• Log In via ssh and admin (no problem there / can switch between folders etc, but I use different port for security)

• node v12 used (v8 would also be available) ...also tried to run a HelloWorld.js via SSH from home ...working

• using a FritzBox-Router with the standard security settings (so far no ports freed for the DS, but DS has standard internet access ...also checked via Package Manager on the DSM, finds packages and also installing there works =way I installed nodev12)

Hopefully someone knows whats the issue / it seems npm has no access to the web/repo??

Thanks in advance!!

Answer 1

have found the solution myself: "sudo ping 1.1.1.1" was already functioning over SSH "sudo ping registry.npmjs.org" got me "Temporary failure in name resolution"

so for Synology go in DSM: Control Panel / Network / General: and set DNS-server manualy (Google etc)

after this it worked! ...hope it helps somebody else
