The Module Named "pm2" is required

General Help

Never thought much about all the different mirrors that would be needed. They have dns filtering because they are a health care provider, HIPPA and all. I have requested that the system be opened to the internet. We shall see what happens.

62

There are many external resources required

Thanks Lorne. I plan on checking them from the pbx tomorrow.

It’s not necessarily lots of “mirrors” (like freepbx mirrors). With node.js applications using npm to install dependencies, the dependencies are all pulled in from wherever on the internet those dependencies are kept. Most are usually on github (because lots of devs use it) but they really could be downloaded from nearly any place on the internet - essentially wherever the node application says they’re located. And those dependencies can have subdependencies declared too… soooo… they can literally be anywhere on the internet. It’s a nasty problem if you have to individually whitelist every single one.

Thanks Matt

I logged into the system (CLI) and did a nslookup for all the domains here: Allowed IPs for PBXact Upgrade - PBX Platforms - Documentation

I got replies from all of them. I do not know where to go at this point. Could NPM be choking somehow?

66

@edlentz - I think you’re on a wild goose chase and it will be very challenging to walk through every dependency in the dependency tree for pm2. You need to try to just open the system up for a few minutes to make this update. That’s just my opinion.

67

I have asked that the system be opened up both to in and out traffic. We will see how that goes.

68

I had the IT manager open the system up (DMZ) and still it times out.

[root@localhost ~]#

It appears to have made some progress

69

on that machine try wget http://mirror1.freepbx.org/npm/pm2-2.10.7.tgz and see what happens

70

I tried that and got the file locally

71

We ran a packet capture from the firewall while I was running the fwconsole ma update pm2. It was a big file! I decided to search DNS requests. I found a request to freepbx.org. I searched for github and got nothing. I am assuming that there would be a request to github for something. Could Node.js or NPM be hosed??

72

Well, as per @jfinstrom - if you can’t download the pm2 package from mirror1 on the machine, you’re not going to get to the point where you’re even be able to install dependencies (which would be from other places). You’ve got to figure out why the pm2 package itself isn’t downloading.

73

Matt,

The system says: Module pm2 successfully downloaded its after that when npm is doing the install It looks like it wants to download the pm2 module twice. What am I missing? Is there a way to make it install the local pm2 file? I can and have downloaded it to the system using the command line.

74

PM2 Is Hard Coded to use the Mirror servers. It will never talk to NPM directly for itself (It will for other packages).

See: pm2/node/package.json at release/13.0 ¡ FreePBX/pm2 ¡ GitHub

It looks like your version of NPM is unable to actually do network commands. It’s pretty far out of scope of most people helping. What you should do is search the internet for how to change settings in NPM.

Heres some information about setting up proxies: Using NPM Install Behind A Corporate Proxy Server | by timothy ogbemudia | Medium

You can also do something like npm install pm2 -g which will install pm2 globally from npmjs.org but this will only tell you if there is an issue with npm and networking on your system (and you should run that after you su asterisk)

75

This also looks like a 13.0 system because in other releases of FreePBX PM2 the module never references mirror

See:

The only one that still references mirror is 13.0

76

Thanks Andrew

I tried

I got
[root@localhost ~]# su asterisk
bash-4.1$ npm install pm2 -g
Error: EACCES, scandir ‘/root’
at Error (native)

Error: EACCES, open ‘npm-debug.log.411535543’
at Error (native)

77

Do you think this system could be upgraded to 15 remotely and would that get us out of this pickle? Or should we get this into the shop and re install Freepbx probably version 15

78

You switched to the asterisk user but your current working directory is /root. You need to switch to a real directory.

Thanks Andrew. We decided to reimage that system and not chase after this any longer. Many thanks to the others for the help
