Error: Cannot find module 'memdown' #413

Leen15 · 2016-02-10T12:45:50Z

Hi, i'm using mosca with a custom dockerfile, where I install node and mosca as follow:

....
# Install nodejs and helpful node packages
RUN apt-get install nodejs -y --force-yes
RUN ln -s /usr/bin/nodejs /usr/bin/node
RUN apt-get install npm -y --force-yes

#Install PostgresSQL client
RUN apt-get install libpq-dev -y --force-yes

# Install Redis.
...
RUN mkdir -p $PROJECT_PATH
COPY . $PROJECT_PATH
WORKDIR $PROJECT_PATH

RUN npm install debug
RUN npm install mosca@latest --save
RUN npm install daemon
RUN npm install bcrypt
RUN npm install jsonwebtoken
RUN npm install pg
RUN npm install pg-native
....

Every time i rebuild the docker image it installs version 0.32.1 of mosca.
So i added @latest to mosca npm module and now it installs correct version 1.0.2.
But when i start the container it doesn't stay up, and i read in log this error:

module.js:340
    throw err;
    ^
Error: Cannot find module 'memdown'

Any Ideas?

Hi Matteo, aptitude installs node 0.10.25.

mcollina · 2016-02-10T13:56:44Z

I would suggest at least 0.10.36 on the 0.10.x line. But I'd suggest you to
use v4.

I am pretty sure that in either case your npm install doesn't run cleanly. Have a look at the output of the docker build.

In your pasted code for node4 it says: gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable. So obviously you are missing python in the docker base image you are using.

So the better question would probably be: what Docker base image are you using?

Ok so instead of use apt repo for install node i tried to use "n":

RUN npm install -g n
RUN n 0.10.36

With this version mosca working fine.

If instead i try to use last node version:

RUN npm install -g n
RUN n stable

I receive this error:

npm ERR! Linux 3.13.0-63-generic

Base image is ubuntu:14.04, with build-essential installed (for install redis).

Thanks for support guys.

I'm trying with various versions.
With node 4.0.0 all working fine, with node 5.6.0 give the error above, with node 5.2.0 it give this error:

But container start and mosca working.
What version of node should i use? I'm not expert of node (i don't know if you did notice yet? :P )

mcollina · 2016-02-10T15:24:17Z

if you are not using zmq there is nothing to worry about.

Leen15 · 2016-02-10T15:29:41Z

Ok so i stay with node 5.2.
Thanks for all :)

jdkanani · 2016-02-21T08:19:42Z

Getting same error with node v5.6.0

jdkanani · 2016-02-21T09:52:02Z

It's npm problem: deleting ~/.npm, npm_modules and installing dependencies did the trick.

uchobby · 2016-03-06T11:15:31Z

I am having this problem with mosca not finding memdown. memdown is installed and in the node_modules directory. I am trying to run the basic example with no backend DB so it should use internal memory...

Here is the code...

var mosca = require('mosca')

var moscaSettings = {
port: 1883,
};

var server = new mosca.Server(moscaSettings);
server.on('ready', setup);

server.on('clientConnected', function(client) {
console.log('client connected', client.id);
});

// fired when a message is received
server.on('published', function(packet, client) {
console.log('Published', packet.payload);
});

// fired when the mqtt server is ready
function setup() {
console.log('Mosca server is up and running')
}

node version...

node --version
v0.10.25

Run the code....

node server.js

result

module.js:340

I did not mean for the formatting on that to yell out.. with bold type etc... sorry, markdown false trigger..LOL

mcollina · 2016-03-06T14:19:57Z

So, update your version of NPM and node. Something went wrong in your installation phase.
And do not use the node.js version from your linux distribution.

rgstephens · 2016-04-25T22:37:56Z

Pulling my hair out on this one. I've tried the latest 0.12 release and had this error, saw that @mcollina recommended v4, so I'm now on v4.4.3 and still have this error. I've avoided installing the standard Ubuntu package as recommended. Not sure where to go next.
