How do I fix EACCES: permission denied, open

Question

I see the following error when executing npm install -g serverless via buildspec.yml from AWS Codebuild

storage-engine@3.0.7 postinstall /usr/local/lib/node_modules/serverless/node_modules/storage-engine node ./compatibility/detect.js

Error: EACCES: permission denied, open '/usr/local/lib/node_modules/serverless/node_modules/storage-engine/lib/compatibility/index.js'

Does this answer your question? [npm throws error without sudo](https://stackoverflow.com/questions/16151018/npm-throws-error-without-sudo) — Elias Soares, Jun 21 '20 at 20:53
I just received the exact same error as you, maybe AWS has changed something? — Niall McKenna, Jun 21 '20 at 21:29
My codebuild pipeline also just started breaking with the same error — Vitor Freitas, Jun 21 '20 at 22:06
For the time being, adding `--unsafe-perm` to the npm install command solved the problem for me. `npm install --silent --progress=false -g --unsafe-perm serverless` — Vitor Freitas, Jun 21 '20 at 23:04
I also met the same problem. And the same issue was reported also on AWS developer forum. https://forums.aws.amazon.com/thread.jspa?threadID=323762 — Koyama Kenta, Jun 22 '20 at 04:23
It looks like it has been fixed. We were able to deploy without --unsafe flag — Francis Zabala, Jun 22 '20 at 07:37
Me too. In my environment, it's also been fixed. I can deploy with doing nothing special. — Koyama Kenta, Jun 23 '20 at 23:40

Used yarn instead of npm.

yarn global add serverless

Use the command

sudo chmod -R 777 {your node module link that is shown in the error}

In this case the link shown in the error is /usr/local/lib/node_modules/serverless/node_modules/storage-engine/lib/compatibility/index.js so your command would be:

sudo chmod -R 777 /usr/local/lib/node_modules/serverless/node_modules/storage-engine/lib/compatibility/index.js
