gometalinter 正在检查 /usr/local/go 个文件

Question

我运行宁 gometalinter 针对一个文件：gometalinter ./src/main.go

但它为 golang 源文件打印错误：

90cc5ff9b2ea:/repo# gometalinter ./src/main.go

如何运行 gometalinter 再次针对一个文件或仅针对 ./src 目录？

我的配置：

{
  "Deadline": "5m",
  "EnableGC": true,
  "Enable": [
    "deadcode",
    "gocyclo",
    "gofmt",
    "gotype",
    "goimports",
    "golint",
    "gosimple",
    "ineffassign",
    "interfacer",
    "misspell",
    "unconvert",
    "unused",
    "vet",
    "varcheck",
    "maligned",
    "errcheck",
    "megacheck",
    "goconst",
    "structcheck"
  ],
  "Cyclo": 10,
  "Aggregate": true
}

此命令在 Docker 容器中启动，基于 golang:alpine 作为 root 用户。
