Unable to install lightbug_http using magic following the latest documentation

[nowex35]

（Sorry, but I'm new to the Mojo community.）

I followed the official Mojo manual for the setup and attempted to install lightbug_http using magic, but it didn't work.

Steps to reproduce the behavior:

1. Start mojo project

magic init LB --format mojoproject

2. Add mojo-community channel to mojoproject.toml

[project]
channels = ["https://conda.modular.com/max-nightly", "https://conda.modular.com/max", "https://repo.prefix.dev/modular-community", "conda-forge", "https://repo.prefix.dev/mojo-community"]

3. Add lightbug_http

[dependencies]
max = ">=25.1.0.dev2025021016,<26"
lightbug_http = ">=0.1.11"

4. Run "magic install" in LB directory

magic install

5. Then, I got the following error:

  × failed to solve the conda requirements of 'default' 'linux-64'
  ╰─▶ Cannot solve the request because of: The following packages are incompatible
      └─ lightbug_http >=0.1.11 cannot be installed because there are no viable options:
         └─ lightbug_http 0.1.11 would require
            └─ small_time ==0.1.6, which cannot be installed because there are no viable options:
               └─ small_time 0.1.6 is excluded because due to strict channel priority not using this option from: 'https://repo.prefix.dev/
      mojo-community/'
      

6. When I changed mojoproject.toml as follows, It worked.

[project]
channels = ["conda-forge", "https://conda.modular.com/max", "https://repo.prefix.dev/mojo-community"]
name = "LB"
platforms = ["linux-64"]
version = "0.1.0"

[tasks]

[dependencies]
max = "24.6.0.*"
lightbug_http = ">=0.1.11"

For comparison, I'll include this (unable version) as well.
＜This is simply an edit based on the 'Getting Started' sections of Mojo and lightbug_http.＞

[project]
channels = ["https://conda.modular.com/max-nightly", "https://conda.modular.com/max", "https://repo.prefix.dev/modular-community", "conda-forge", "https://repo.prefix.dev/mojo-community"]
name = "LB"
platforms = ["linux-64"]
version = "0.1.0"

[tasks]

[dependencies]
max = ">=25.1.0.dev2025021016,<26"
lightbug_http = ">=0.1.11"

It also failed.

[project]
channels = ["https://conda.modular.com/max-nightly", "https://conda.modular.com/max", "https://repo.prefix.dev/modular-community", "conda-forge"]
name = "LB"
platforms = ["linux-64"]
version = "0.1.0"

[tasks]

[dependencies]
max = "24.6.0.*"
lightbug_http = ">=0.1.11"

Could this be an issue caused by the latest dependencies or wrong channels? If I’m mistaken, I apologize.

Thank you for the thorough bug report!
The issue here is that Lightbug hasn't been yet uploaded to the official modular-community channel, only to the unofficial mojo-community one.

Not sure what happens here exactly, but most likely when both channels are included in the channel list there's a clash, and magic can't get some of the dependencies.
For now the way to go is still to use the mojo-community channel.

I hope in a couple days we can resolve the latest issues with CI in the Modular repo and get Lightbug added to the modular-community channel. Once that works, we'll transition to this as the main one.

Thank you for your reply.
I understand the situation.
