Hermes configuration is wrong, don't rush to reinstall. The most common repair sequence is: first run 'hermes config check' to see what is missing, then use 'hermes config migrate' to fill in the new items, and finally use 'hermes doctor --fix' to do automatic repairs. Most of the errors reported after the update are essentially a mismatch between the old configuration and the new version.
What do the three commands do separately?
| order | Function | When to use |
|---|---|---|
| config check | Check for missing and outdated configurations | Error after upgrade |
| config migrate | Interactive completion of new options | The inspection results indicate missing items |
| doctor --fix | Do automatic diagnostics and repairs | The service, the gateway, the memory are unstable |
Hermes' configuration is mainly divided into '~/.hermes/config.yaml', '.env', and 'auth.json'. If it is a model, terminal, compression, memory, etc., look at 'config.yaml' first. If it's API key, OAuth, token, look at '.env' and 'auth.json'. This layering is very important, otherwise you will change the problem in the wrong place.
The most practical experience is that 'config check' is responsible for positioning, 'config migrate' is responsible for completion, and 'doctor' is responsible for verifying that the entire system is healthy. Compared to blind deleting the directory, this is more stable and easier to keep the habit configuration you have adjusted.
Summary in one sentence: Hermes configuration is broken, check first, then migrate, and finally repair, don't reinstall it in the first step.
