Resolving Hex dependencies... Failed to use X because Y dependency requires specific version ... 🤦‍♂️ #182

Open nelsonic opened 1 year ago

nelsonic commented 1 year ago

We recently had this happen in https://github.com/dwyl/auth_plug/issues/76 and it's happened in the past too. ⏳

It's happening to me in the auth project while I try to update Fields:

mix deps.get
Resolving Hex dependencies...

Failed to use "ecto" (versions 3.3.0 to 3.9.1) because

** (Mix) Hex dependency resolution failed, change the version requirements of your dependencies 
or unlock them (by using mix deps.update or mix deps.unlock). 
If you are unable to resolve the conflicts you can try overriding with {:dependency, "~> 1.0", override: true}

As noted in https://github.com/dwyl/auth_plug/issues/76#issuecomment-1277847197 this is one of my biggest frustrations with Hex. 😢 By upgrading to a later version of a dependency e.g. jason or plug in one of the packages we "control", we are no longer able to use the package in a project where a different dependency relies on on an older version! So we are forced to conform to the lowest common denominator in terms of updates. Which is really bad for both security and performance. 🤦‍♂️ When a newer version of a package is released, provided all tests continue passing, everyone should use it!

Ran:

mix deps.unlock --all

Followed by:

mix deps.get

Got:

Resolving Hex dependencies...
The dependency resolver is taking more than 30 seconds. This typically happens when Hex cannot find a suitable set of dependencies that match your requirements. Here are some suggestions:

  1. Do not delete mix.lock. If you want to update some dependencies, do mix deps.update dep1 dep2 dep3

  2. Tighten up your dependency requirements to the latest version. Instead of {:my_dep, ">= 1.0.0"}, try {:my_dep, "~> 3.6"}

Took a break to refill my water bottle and when I returned to my desk I spent a few mins checking my GH Notifications ... ⏳ It's been 10 mins and the fans on my Mac are running like jet engines and zero progress on downloading the deps! 🤷‍♂️

Had to kill the mix deps.get as it seemed like it hung my terminal. 💀 Downgrade my version of Fields from 2.9.1 to 2.8.2 and then re-installed everything mix deps.get. 🙃 This is annoying ... 🤦‍♂️

Need a permanent solution to this. 💭 Parking for now but will return to it ASAP.

Lame. 🤦‍♂️ Unpicking now. ⏳

nelsonic commented 1 year ago

Downgrading the required version of ecto in the fields project from:

{:ecto, "~> 3.8"},

To:

{:ecto, "~> 3.3"},

To match: https://github.com/phoenixframework/phoenix_ecto/blob/2cf35cf2e441416bfb82b72aafc1659a12873cd2/mix.exs#L55

And thus avoid compatibility issues! 🤞

From bad to much worse! 🤦‍♂️ Looks like it's going to be a looooong evening! ⏳
