Installation problem

[sharonyue]

I followed the setup guide written here https://docs.nodebb.org/installing/os/ubuntu/ and it shows such problem and was stuck there....

What version of node and npm?

[sharonyue]

$ node -v
v12.16.3
$ npm -v
6.14.4

Its a fresh server, and I am sure I did nothing wrong and it should work.

I tried ./nodebb setup again, it says:

y@iZ8vb5zw2bx60ytuhcwlwiZ:~/nodebb$ ./nodebb setup

Does npm i connect-multiparty work on it's own??

[sharonyue]

It says

~/nodebb$ npm i connect-multiparty

I input npm cache clean --force and the problem is solved, I dont know why though.

[sharonyue]

@sharonyue said in Installation problem:

npm cache clean --force

I install a new test server and run into this problem again...I dont know where the problem come from but the command above fixed it.

How about we fix that in nodebb code? or is it coming from my OS? I using ubuntu 18.04. I dont know..

[PitaJ]

This is a problem with npm. You could try using yarn instead, but it's not something that nodebb can fix.
