I am trying to install one of my extension via the extension manager, and I get the "not a valid zip" error message. I was trying to debug brackets, but running the latest code keeps on closing my chrome instance; I am running brackets 33, which apparently needs an updated shell to run latest code.

This is the URL I am trying to install.

Same thing happens when I install from the registry. Any help would be great!

If this helps, I was able to get some information about the error.

The error happens in package-validator.js:extractAndValidateFiles. unzipper.on("error"... is called with the message below.

[node-log 9:26:28 AM] decompress: [Error: Unsupported file type "SymbolicLink"] NodeDebugUtils.js:117
[node-log 9:26:28 AM] validate callback: null { errors:
[ [ 'INVALID_ZIP_FILE',
'/var/folders/76/79415zbs2cd3gl630nf_jy8h0000gp/T/brackets113108-5552-1lwxu5p' ] ] } NodeDebugUtils.js:117

@MiguelCastillo How did you create the zip file? One of my extensions is having issues too.

I always do the "Download Zip" from my github repo and push that... So, whatever github zip creation process does is out of my control. So, I load up the zip into the plugin registry and I also load using the url link; both have the same problem.

So, I finally found the cause of the issue. DecompressZip chokes when processing files with type "SymbolicLink". Once I identified which ones were symbolic links, I deleted them from my repo and things are working again.

Tips for debugging:

1. Open up "extensibility/node/node_modules/decompress_zip/lib/decompress_zip.js"
2. Go to line 81 and add a console.out to see all the files that are going to be decompressed. This is what my statement looked like:
   .then(function (files) {
   console.log("files", files, options);
   var promises = [];
3. Look at Chrome Debug console and search for "SymbolicLink". You should be able to find the offending files. :)

Happy debugging!

BTW, I am not sure if there is a clean way to handle symlinks besides deleting them... Maybe there is an option we can pass into DecompressZip to ignore certain file types?

Nominating for sprint 35, on the assumption that symlinks might be common in some node use cases (since I think some node modules create things link symlinks into a bin folder?). I don't really know if it's that common though.
