Ubuntu 16.04 mean.js installation (without using one click app)

June 17, 2017 144

MEAN Node.js Ubuntu 16.04

I am trying to install mean.js on my ubuntu 16.04 using the following guide. And I keep getting stuck at the grunt stage.

https://www.digitalocean.com/community/tutorials/how-to-install-a-mean-js-stack-on-an-ubuntu-14-04-server

There were issues with building node so I install using nvm
https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-ubuntu-16-04#how-to-install-using-nvm

Then there were issues with bower where the process was killed. Managed to solved that by adding swap. I have the 512 MB ram settings.
https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04

Now my problem is grunt. I now have this error.

/opt/mean$ grunt
A valid Gruntfile could not be found. Please see the getting started guide for
more information on how to configure grunt: http://gruntjs.com/getting-started
Fatal error: Unable to find Gruntfile.

Then when I tried

/opt/mean$ npm install
npm WARN checkPermissions Missing write access to /opt/mean/nodemodules/tiny-lr/nodemodules
npm WARN checkPermissions Missing write access to /opt/mean/nodemodules/tiny-lr/nodemodules/body-parser/nodemodules

This is my second droplet try.

If anyone need me to edit the question or require more information, just leave a message.

Hi @tengyong80

From looking at the error log, it looks like you don't have permissions to the /opt/mean directory with the current user you're logged in as.
So either change permissions to allow that user access - or run the commands as root or with sudo.

Hi @hansen

My user is a root user. I created it following the link below.
https://www.digitalocean.com/community/tutorials/how-to-create-a-sudo-user-on-ubuntu-quickstart

When I tried using

/opt/mean$ sudo npm install
npm WARN lifecycle meanjs@0.5.0~postinstall: cannot run in wd %s %s (wd=%s) meanjs@0.5.0 npm run bower /opt/mean
npm WARN eslint-config-airbnb@6.0.2 requires a peer of eslint-plugin-react@^4.0.0 but none was installed.
removed 12 packages and updated 1 package in 12.66s

Then I tried using

opt/mean$ grunt
A valid Gruntfile could not be found. Please see the getting started guide for
more information on how to configure grunt: http://gruntjs.com/getting-started
Fatal error: Unable to find Gruntfile.

How To Create a Sudo User on Ubuntu [Quickstart]
The sudo command provides a mechanism for granting administrator privileges, ordinarily only available to the root user, to normal users. This guide will show you the easiest way to create a new user with sudo access on Ubuntu, without having to modify your server's sudoers file.

  If you were root, then opt/mean$ would be opt/mean#.
  You can run the command whoami to see which user you're currently using.
  Is there a special reason why you want to compile it instead of using a PPA?

  I change the settings to PermitRootLogin yes for root login and repeated the process.
  
  /opt/mean# sudo npm install
  npm WARN lifecycle meanjs@0.5.0~postinstall: cannot run in wd %s %s (wd=%s) meanjs@0.5.0 npm run bower /opt/mean
  npm WARN eslint-config-airbnb@6.0.2 requires a peer of eslint-plugin-react@^4.0.0 but none was installed.

  /opt/mean# sudo grunt

  Fatal error: Unable to find Gruntfile.
  
  I got the same message for root too. I thought that if I am using a sudo user, I no longer have to use root user?
  
  My previous user has sudo rights. For example
  root@nodejs-ssl-deploy:~# id jason
  uid=1000(jason) gid=1000(jason) groups=1000(jason),27(sudo)
  
  I based my reason on the following guide. It mentioned that
  "While the packaged version in Ubuntu's repository is the easiest, the nvm method is definitely much more flexible."
  So I decided to go with nvm.

  To be honest this is my second failed droplet. My first droplet failed at gulp using the tutorial below.
  https://linuxacademy.com/howtoguides/posts/show/topic/11960-how-to-install-mean-on-ubuntu-1604
  
  I seem to be stuck at the either grunt or gulp. The main difference between the first and second droplet is I added swap for the second droplet.

@tengyong80

You're totally right, when you use sudo you don't need to use the root login, but your first post didn't use sudo or root.

All the errors involves some type of permissions problem, so have a look at these:

Hi @hansen

I started with the first link and when I used npm config get prefix, I get
/home/myuser/.nvm/versions/node/v6.11.0 instead of /usr/local or /usr

myuser is the sudo user that I created. when I changed to root and used npm config get prefix,
I get the same output.

Could this be the caused of all my previous error?

https://www.digitalocean.com/community/tutorials/how-to-install-node-js-with-nvm-node-version-manager-on-a-vps

I tried to use n=$(which node);n=${n%/bin/node}; chmod -R 755 $n/bin/*; sudo cp -r $n/{bin,lib,share} /usr/local from the link above and still it's pointing to home instead of /usr/local/bin/node

  I have never tried compiling Node.js, since I didn't need any function which wasn't already in the default repository, so I'm not familiar with that error, but it seems like that's the problem - how to solve it, I'm unsure.

  Could you show me which guide you used?

  I will try that as well. I really wished the nvm method works though.
