1 flag provided but not defined: -test.timeout 很显然,跑go test时涉及到了flag解析。 go test是以package为单位进行测试的(无论是否通过-run指定特性test函数),所以一定是test所在的包内包含了flag解析逻辑或import了需要进行flag解析的其他package. 此错误有些类似于package的循环引用。 一般来说考虑如下解除方...

在执行flag.String后,记得执行flag.Parse来解析命令,否则不能执行成功。我们来测试一下,先键入一个错的参数,会得到以下提示。 Copy go run main.go -i flag provided but not defined: -i Usage of /var/folders/3s/5v6r481x17x5ks_7q1dzmlsw0000gp/T/go-build400337564/b001/exe/main: -ip string 此...
