claude-code - 💡(How to fix) Fix Plugin install uses SSH clone even when HTTPS URL is specified [2 comments, 3 participants]

1. /plugin install plugin-name@marketplace-name — fails with SSH error Plugins cannot fix this because the error occurs during installation, before any hooks are registered.

TL;DR

The system should use HTTPS for cloning when the source specifies an HTTPS URL, and a workaround is to manually add GitHub's host key to ~/.ssh/known_hosts before installing plugins.

Guidance

• Verify that the marketplace source URL starts with "https" to ensure it's not an SSH URL.
• Run the provided command mkdir -p ~/.ssh && ssh-keyscan github.com >> ~/.ssh/known_hosts 2>/dev/null before installing plugins as a temporary workaround.
• Consider modifying the plugin installation process to automatically use HTTPS cloning when the source URL is an HTTPS URL.
• Check if the Claude Code CLI has any configuration options to specify the cloning protocol (HTTPS or SSH) for plugin installation.

Example

No code snippet is provided as the issue does not require a code change, but rather a configuration or process change.

Notes

This solution assumes that the Claude Code CLI does not have a built-in mechanism to handle host key verification for SSH cloning. The workaround provided may not be suitable for all environments, especially those with strict security policies.

Recommendation

Apply workaround: Manually add GitHub's host key to ~/.ssh/known_hosts before installing plugins, as this is a simple and effective solution to the problem, although it may not be the most elegant or long-term fix.
