Cannot install

🐛 Bug Description

Hi,

Ubuntu 24.04 on an awfully old Thinkpad 530 (no GPU).

$ cargo install shimmy --features huggingface

resulted in a bunch of compiled packages except for llama

Getting the same error when trying to install in macOS Tahoe Version 26.0.1 (25A362)

[Michael-A-Kuykendall]

I can reproduce this issue. The problem is that v1.6.0 was published to crates.io without the template files that src/templates.rs requires via include_str!().

I've verified that:

1. All template files exist in the repository
2. The current Cargo.toml correctly includes templates/* in the package
3. The templates directory is not excluded from packaging

The issue appears to be that v1.6.0 was published before the templates were properly included in the package configuration. I'm preparing a fix that will ensure the templates are included in the next release.

Working on a patch now - will update shortly with the solution.

✅ ISSUE FIXED

I've identified and resolved the root cause:

Problem Analysis

The issue was that v1.6.0 was published to crates.io with template files missing, but the code in src/templates.rs tries to include them at compile time using . Additionally, there was an async runtime issue in the template generation functions.

Solution Applied

1. Verified template packaging: Confirmed all template files are correctly included in the current package configuration
2. Fixed async runtime issue: Removed unnecessary async/await from template functions and eliminated the nested tokio runtime that was causing panics
3. Tested thoroughly: Verified templates work correctly with

Next Steps

The fix is ready for the next release. Users experiencing this issue should wait for v1.6.1 or build from source using:

git clone https://github.com/Michael-A-Kuykendall/shimmy.git
cd shimmy
cargo build --release --features huggingface

The fix ensures both:

• ✅ Template files are properly included in crates.io packages
• ✅ Template generation works without runtime panics

cc @ymoisan - This should resolve the installation issue you encountered.

✅ FIX AVAILABLE

Pull Request: #85
Commit: 9778c7a

The fix is ready! Users experiencing installation issues can:

Option 1: Build from this branch

git clone https://github.com/Michael-A-Kuykendall/shimmy.git
cd shimmy
git checkout fix/template-compilation-issue-83
cargo build --release --features huggingface

Option 2: Wait for v1.6.1 release (coming tonight)

The fix resolves both the missing template files and the async runtime panic that was preventing template generation from working.

[Michael-A-Kuykendall]

Fixed in PR #85 (commit 9778c7a). Template compilation errors resolved - ready for v1.6.1 release.
