The Module Named "pm2" is required

Marbled · April 21, 2017, 11:32am

Hi!

Install “Process Management” in Module Admin…

For some weird reason the very short “internal name” of that module (pm2) is used when dependencies are shown instead of its description (“Process Management”).

I never noticed and it most likely always does that but this time the module name does not help much figure out what to install…

Good luck and have a nice day!

Great…worked for me…thanks adventurer

kbocek · April 25, 2017, 6:52pm

This didn’t work for me:

# fwconsole ma downloadinstall pm2
No repos specified, using: [standard,extended,unsupported] from last GUI settings

Starting pm2 download..
Processing pm2
Verifying local module download...Verified
Extracting...Done
Module pm2 successfully downloaded
sh: 1: node: not found
Node is not installed
Unable to install module pm2:
 - Failed to run installation scripts

Any ideas?

tm1000 · April 25, 2017, 6:54pm

The answer is right there. You need to install nodejs

kbocek · April 25, 2017, 7:39pm

Nope.

# fwconsole ma downloadinstall nodejs
No repos specified, using: [standard,extended,unsupported] from last GUI settings

Starting nodejs download..
The following error(s) occured:
 - Retrieved Module XML Was Empty

lgaetz · April 25, 2017, 7:42pm

yum install nodejs

kbocek · April 25, 2017, 7:47pm

Just figured out that it is an OS level package. In my case:

apt-get install nodejs
apt-get install node

But alas still no go on pm2:

# fwconsole ma downloadinstall pm2
No repos specified, using: [standard,extended,unsupported] from last GUI settings

Starting pm2 download..

Found a hint that the correct package for Raspian is nodejs-legacy. After removing the first two and installing that I get:

# fwconsole ma downloadinstall pm2

tm1000 · April 25, 2017, 8:02pm

Sorry but you need to install nodejs 0.12.18 or higher. This is most easily accomplished by using the FreePBX Distro. Since you are on a Raspian there’s not much we can do other than tell you that you need 0.12.18 or higher.

Node JS is not a module in FreePBX. It is a requirement outside of that. When you use systems that are not the FreePBX Distro you will most likely have to build things manually or find them somewhere else.

The command that is run to check node and npm is:

node --version
npm --version

kbocek · April 25, 2017, 11:49pm

Figured it out. I installed nodejs following the instructions here:

https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions

Then the pm2 install worked:

# fwconsole ma downloadinstall pm2   
...
 Finished updating libraries!
    Generating CSS...Done
    Module pm2 successfully installed
Updating Hooks...Done

# node -v
v6.10.2

Thank you for the help.

munozj · May 25, 2017, 5:08pm

Having some similar trouble installing the proper version of nodejs to be able to install pm2.

Using CentOS 6.9 and FreePBX 13

I used these instructions to install nodejs

But when I try and run:

#fwconsole ma downloadinstall pm2
No repos specified, using: [standard,extended,unsupported,commercial] from last GUI settings

Starting pm2 download..

I can see that I don’t have the right version of nodjs but can’t figure out how to upgrade. This is more of OS issue than a freepbx issue but perhaps someone could nudge me in the right direction?

tm1000 · May 25, 2017, 5:40pm

Since you aren’t using the distro (and if you are DO NOT DO THIS)

curl -sL https://rpm.nodesource.com/setup_0.12 | bash -
yum install -y nodejs

posi211 · May 25, 2017, 8:38pm

I had the same issue for a new distro install. I downloaded the distro USB image yesterday.

Jas_williams · May 27, 2017, 7:28am

If you are running the free pbx distro the yum install nodejs will work for you it is a recent dependency for some recently upgraded modules

lgaetz · May 27, 2017, 11:31am

If you are running the distro, and keeping current with distro updates, then you would already have nodejs installed:

Process Management is found in Module Admin under Extended modules not Standard.

NDSiouxFan · June 27, 2017, 9:17pm

I am getting the same error. FreePBX Distro 13.0.192.9 with all current updates. Run “yum install nodejs” and get

Package nodejs-0.12.18-1nodesource.el6.x86_64 already installed and latest version. Nothing to do

Run “fwconsole ma downloadinstall pm2” and get the following two errors:

[npm-cache] [INFO] [composer] Dependency config file /var/www/html/admin/modules/pm2/node/composer.json does not exist. Skipping install

[npm-cache] [INFO] [bower] Dependency config file /var/www/html/admin/modules/pm2/node/bower.json does not exist. Skipping install

Any ideas how to fix this? In Module Admin, PM2 is “Disabled: Pending upgrade to 13.0.3.15” The current version shows as 13.0.3.13

tm1000 · June 27, 2017, 9:26pm

Those aren’t errors. Can you provide the full output.

Hello @able,

I stumbled on this problem with some of my servers. For some reason the nodejs modules are not downloaded with the rest of the PM2 module (especially the debug module). I guess it is a timeout of one of the HTTP servers somewhere in the way because many of my Freepbx servers are being upgraded fine with the PM2 module.

What I am doing to bypass this problem is just copying a working PM2 module directory from another server with SCP and then I am “installing” the PM2 module.

Let us assume that you have a working and updated PM2 module with an ip address of 1.1.1.1 and a non working Freepbx server with an ip address of 2.2.2.2

Here are the steps:

Remove the PM2 module directory from the non working Freepbx (2.2.2.2)
rm -rf /var/www/html/admin/modules/pm2
Copy the working PM2 directory from 1.1.1.1 to 2.2.2.2
scp -r /var/www/html/admin/modules/pm2 [email protected]:/var/www/html/admin/modules/
Install the PM2 module on 2.2.2.2 after the copy of the working module
fwconsole ma install pm2
Upgrade the rest of the modules on 2.2.2.2
fwconsole ma upgradeall
Reload the Freepbx framework on 2.2.2.2
fwconsole reload
Restart the Freepbx framework
fwconsole stop && fwconsole start

Thank you,
