Attempted Troubleshooting

stream.js:74
      throw er; // Unhandled stream error in pipe.
      ^

Error: EPERM: operation not permitted, chmod '/var/www/hong.io/koel/public/css/app.css'
    at Error (native)

This appears to be some sort of permissions error, as it states the operation is not permitted. I attempted to resolve this issue by deleting the contents of node_modules again (rm -rf node_modules) and rerunning npm install as root.

sudo npm install

This results in the following output

It appears the upgrade failed at another step in the process, and did not resolve.

<!-- gh-comment-id:261924927 --> @ShenZhouHong commented on GitHub (Nov 21, 2016): # Attempted Troubleshooting ``` stream.js:74 throw er; // Unhandled stream error in pipe. ^ Error: EPERM: operation not permitted, chmod '/var/www/hong.io/koel/public/css/app.css' at Error (native) ``` This appears to be some sort of permissions error, as it states the operation is not permitted. I attempted to resolve this issue by deleting the contents of node_modules again (`rm -rf node_modules`) and rerunning npm install as root. ``` sudo npm install ``` This results in the following output ``` npm WARN lifecycle koel@~postinstall: cannot run in wd %s %s (wd=%s) koel@ cross-env NODE_ENV=production && gulp --production /var/www/hong.io/koel npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/chokidar/node_modules/fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.0.15: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"}) npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/gulp-watch/node_modules/chokidar/node_modules/fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.0.15: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"}) shen@pattensen:/var/www/hong.io/koel$ rm -rf node_modules/ shen@pattensen:/var/www/hong.io/koel$ sudo npm install npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue npm WARN deprecated minimatch@0.2.14: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue npm WARN deprecated graceful-fs@1.2.3: graceful-fs v3.0.0 and before will fail on node releases >= v7.0.

Your issue explanation is very detailed, great to see!

Looking through the logs you concluded right that you have an permission issue, however it occurred in your public/css folder and not in node_modules as you though. Your Koel looks to be installed under the user www-data and you tried to update it using shen.
Additionally to that on your second attempt you've hit some bad luck and the re-installation of one dependency failed, which in turn made it fail the frontend update again.

To get things back on track you'll need to execute a few commands. Be sure to copy them precisely, some can, if used wrong, damage your system.

First, go to the folder you installed Koel in:
cd /var/www/hong.io/koel/
Clean up the failed dependency installation:
sudo rm -r node_modules
Correct the permissions in the folder:
sudo chown -Rv www-data:www-data .
Reinstall the required dependencies:
sudo -Hu www-data npm install

This last install step should also setup all frontend files, you can check this by reading the output. These two lines followed by no errors should be output:

> koel@ postinstall /var/www/hong.io/koel
> cross-env NODE_ENV=production && gulp --production

If that is not the case you can manually trigger a frontend update using the following command:
./node_modules/.bin/cross-env NODE_ENV=production && sudo -Hu www-data ./node_modules/.bin/gulp --production

Like before this also looks like a permissions issue. However, in this case, I believe I knew the solution. koel was not actually installed as the www-data user, but rather under a newly-created koel user specifically for that process. Therefore, when using `sudo -Hu www-data npm install, it (expectedly) did not work as permissions were still incorrect.

In order to solve this issue, I merely repeated your commands substituting koel for the user (which is also a group member of www-data, so I left the group unchanged).

This resulted in the expected output.

So, in summery and for future reference:

Make sure that the file and group permissions on your koel installation are correct - and that NPM has access to change and modify the files.

For future users that may be Googling the issue, here are some tips:

• Check the output of ls -al on your koel directory. The user and group permissions should make sense.
• If the permissions are incorrect, follow @gamerlv 's suggestion from above. You may need to change the names for your configuration.
