config/engine-version

The project needs a different version of yuanme than the one running: yuanme = "X.Y" is the oldest compatible version, with Cargo’s caret meaning, so 1.2 accepts any 1.x from 1.2 on and 0.3 accepts only 0.3.x.

Example

yuanme = "9.0"

[site]
url = "https://example.com"

Fix

Install a version of yuanme that the project accepts, with yuanme self update X.Y.Z, or change yuanme = if the project really works with the version you have.
