Question

我在配置/初始化程序中添加了这些行

require 'memprof/middleware'
config.middlewares.use(Memprof::Middleware)

require 'memprof/tracer'
config.middleware.insert(0, Memprof::Tracer)

获取此错误

而不是

config.middlewares.use(Memprof::Middleware)

试

config.middleware.use(Memprof::Middleware)

如何在Rails 2.3.14应用程序中配置memprof？
