Question:
I’ve created a pre-configured node.js instance on AWS using ElasticBeanstalk, but the application does not run correctly. SO I connected to the instance and found out there is no node or angular cli, so I installed them manually. I then tried to run npm install in the application folder but failed, here is the output error.

I already installed node using version manager nvm, and tried also chown permission to nodejs:

I appreciate if someone could help me resolve this problem,
Thanks.
Answer:
It’s a LINUX permissions issue, your ec2-user doesn’t have write permissions in that directory.
I faced the same issue recently and my workaround was the following:
Note that I’m not an expert in UNIX neither AWS so maybe there is a better/cleaner/easier solution to this issue.
Having node and npm installed globally:
Log as root user using: sudo su and run npm install
Having node and npm only installed in ec2-user:
- Log as root user using:
sudo su - Create a group of users:
sudo groupadd mygroup - Now that the group exists, add users to it:
|
1 2 3 |
sudo usermod -a -G mygroup root sudo usermod -a -G mygroup uc2-user |
- Now all that’s left is to set the permissions on the directory:
|
1 2 3 |
sudo chgrp -R mygroup /path/to/the/directory sudo chmod -R 777 /path/to/the/directory |
- Now you can exit as root user:
exitand runnpm installas ec2-user
