使用buffalo框架，
我试着跑buffalo dev米
期望看到:
在端口3000上运行的项目
但我却收到了这些错误信息
actions/app.go:4:2: missing go.sum entry for module providing package github.com/gobuffalo/buffalo (imported by sc_api/actions); to add:go get sc_api/actions
actions/app.go:13:2: missing go.sum entry for module providing package github.com/gobuffalo/mw-csrf (imported by sc_api/actions); to add: go get sc_api/actions
BUBALO已生成actions/app.go，但如果您想知道错误是否与此文件中的IMPORT语句匹配，请注意.
// app.go
package actions
import (
"github.com/gobuffalo/buffalo" // 1rst line
"github.com/gobuffalo/envy"
forcessl "github.com/gobuffalo/mw-forcessl"
paramlogger "github.com/gobuffalo/mw-paramlogger"
"github.com/unrolled/secure"
"sc_api/models"
"github.com/gobuffalo/buffalo-pop/v2/pop/popmw"
csrf "github.com/gobuffalo/mw-csrf" // 2nd line
i18n "github.com/gobuffalo/mw-i18n"
"github.com/gobuffalo/packr/v2"
)
这是什么意思？我怎么才能修好它呢？
