Error deploying node.js app to Amazon Elastic beanstalk

Question

I recently deployed a new node.js app on beanstalk and keep running into the following error?

[Instance: i-cce89e4a] Command failed on instance. Return code: 1 Output: (TRUNCATED)...opt/elasticbeanstalk/containerfiles/ebnode.py", line 180, in npm_install raise e subprocess.CalledProcessError: Command '['/opt/elasticbeanstalk/node-install/node-v4.4.6-linux-x64/bin/npm', '--production', 'rebuild']' returned non-zero exit status 254. Hook /opt/elasticbeanstalk/hooks/configdeploy/pre/50npm.sh failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.

My version of node is: 4.4.7

The deployment seems to be failing at the last line below:

 except Exception, e:
            npm_debug_log = '/var/log/nodejs/npm-debug.log'
            app_npm_debug_log = os.path.join(app_path, "npm-debug.log")
            write_event('Failed to run npm install. Snapshot logs for more details.', 'ERROR')
            if not os.path.exists(app_npm_debug_log):
                utc_time_str = datetime.datetime.utcnow().strftime("UTC %Y/%m/%d %H:%M:%S")
                err_msg = str.format("{0} cannot find application npm debug log at {1} \n", utc_time_str, app_npm_debug_log)
                print(err_msg)
                with open(npm_debug_log, 'a') as f:
                    f.write(err_msg)
            else:
                shutil.copyfile(app_npm_debug_log, npm_debug_log)
            raise e

I cant seem to find any solid solution out there?

I manually zipped and uplaoded the files.

The app works perfectly locally.

Can anyone help?

Answer 1

I don't have enough information to answer... What does the /var/log/eb-activity.log say ?

...But I encounter a similar error when running an npm install on a beanstalk with a t2.small : it had not enough RAM, npm failed. Upgrading to a bigger instance solve the problem. (commiting node_module could also solve this problem, but I didn't wanted to).

What you should do is connect with SSH to the instance, and watch with top/htop what is happening when deploying.

Answer 2

After hours searching why the deploy fails. I can say that any of the following points could resolve the problem.

• Change nodejs version in the elacticbeanstalk configuration
• Change instance type from t2.micro to t2.small in the elacticbeanstalk configuration
• Set the new command that elasticbeanstalk will run when launch node application (according to your requirements) in the elacticbeanstalk configuration
• Or create a .npmrc file in root project with this content

# Force npm to run node-gyp also as root, preventing permission denied errors in AWS with npm@5
