golang的 variable declared but not used 和 package imported but not used 在调试代码的时候很不方便!!! 这么多语言中只有golang会有变量不使用, 包引用不用报错的! 方法: 修改golang源码, 将error错误改成warn错误(在eclipse上都会显示红色错误, 但warn不影响编译), 重新编译源码. 解决:declared but not u...

尝试编译这段代码将得到错误 a declared and not used 此外,单纯地给 a 赋值也是不够的,这个值必须被使用,所以使用 在同一个作用域中,已存在同名的变量,则之后的声明初始化,则退化为赋值操作。但这个前提是,最少要有一个新的变量被定义,且在同一作用域,例如,下面的y就是新定义的变量 ...
