Swift vapor 3 ViewRenderer 错误

Swift vapor 3 ViewRenderer error

那是错误

Please choose which ViewRenderer you prefer, multiple are available: PlaintextRenderer, LeafRenderer.

那是我在 configure.swift

中的代码
try services.register(LeafProvider())
config.prefer(LeafRenderer.self, for: TemplateRenderer.self)

叶子添加到 Package.swift

.target(name: "App", dependencies: ["Vapor", "FluentSQLite", "Crypto", "Leaf"]),

尽管我做了 vapor xcode , Build运行也是,但是还是不行。

// As of Vapor 3.0.1 and Leaf 3.0.0-rc.2.2
config.prefer(LeafRenderer.self, for: ViewRenderer.self)
