mime dependency breaking changes

[valtlfelipe]

node-mime has released a new version, which requires node>=6. And in package.json of knox requires mim in any version "mime": "*",.

My enviorment uses node 4, and this just broke my application.

Please merge #325.

See the stack trace.

Similar problem. We use Node 8 but instead we get a runtime error.

ERROR TypeError: mime.lookup is not a function

I have the same problem that @valtlfelipe

[PyroSA]

Same issue. Old 0.12.7 server got re-initialised this morning.

[PyroSA]

Thanks @valtlfelipe & @neebz
You can temporarily use their fixed version of 0.9.2 by using:
"knox": "git://github.com/caremerge/knox.git#b1e031c209b3c17cab622a458e87728c1ee88cbd",
In your package.json

[dwjft]

It seems this package is no longer maintained.

I have created a clone with the fix here: https://www.npmjs.com/package/knox-s3

No other changes other than pinning the mime version.

[manuelxaguilar]

So there's no chance of getting this fixed? I'm not using Knox directly, I'm actually using Keystone, which has Knox as a dependency itself, so I keep getting this mime.lookup error. Any suggestions if this won't get fixed?

[valtlfelipe]

@manuelxaguilar You will have to open an issue at Keystone, so they can change the konx dependency to use @dwjft fork for example 😞

[sedge]

@manuelxaguilar @valtlfelipe You can also investigate npm shrinkwrap to prevent this sort of thing in the future.

[manuelxaguilar]

@valtlfelipe Yeah, I brought it up but they seem to take forever to reply... We'll see I guess.

@sedge I'm using Yarn on my project, which I believe doesn't work well with npm-shrinkwrap. I actually used resolutions to determine which version of Knox to use (I used @PyroSA fork) and it worked well on development, however it failed when deploying to Heroku because it wasn't recognizing git as a valid protocol. :/
