但到了Linux上,就会报错:
# command-line-arguments./http_register.go:113:15: invalid operation: uint64(in) >> i (shift count type int, must be unsigned integer)./http_register.go:175:16: invalid operation: x << (y & (32 - 1)) (shift count type int32, must be unsigned integer)./http_register.go:175:47: invalid operation: uint32(x) >> (32 - y & (32 - 1)) (shift count type int32, must be unsigned integer)./http_register.go:179:24: invalid operation: uint32(x) >> (y & (32 - 1)) (shift count type int32, must be unsigned integer)./http_register.go:179:47: invalid operation: x << (32 - y & (32 - 1)) (shift count type int32, must be unsigned integer)而在Mac上进行穿插编译:
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build 文件名.go(如果呈现GOROOT blabla之类的,执行go env -w GO111MODULE=off )
也没有什么问题
导致这种状况的起因,可能因Go版本不同而导致
Mac上的Go版本为 1.16, 而Linux上Go版本为 1.11
解决:
最后想看一下有没有在线的不同Go版本执行工具,无果而终.
想到之前用php时,用过brew switch来切换不同的php版本.但搜寻之后发现,这个命令被 brew 弃用了.
之前用过node版本工具nvm,于是试图找寻Go有没有相似工具,发现了gvm.
装置gvm
$ bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)N.B. : 不同操作系统还须要装置所需依赖，如Mac须要执行brew install mercurial装置mercurial。具体见原始我的项目
另外如果呈现“ERROR: Unrecognized command line argument: 'use'”报错，可参考此文,执行：
cp -rp .gvm/scripts/env/use .gvm/scripts/usechmod 775 .gvm/scripts/use装置go 1.11
gvm install go1.11抉择版本
gvm use go1.11果然曾经变为 Go 1.11
在 Go 1.11 环境下执行,果然呈现了和在Linux上Go 1.11下呈现的同样谬误
gvm更多命令

其余计划--IDE
不论对于Python,还是Golang,面对版本问题时,应用PyCharm或GoLand,始终是极好的抉择
但当初只能下载最近几个版本，更长远的无奈装置
其余计划--Docker
docker pull golang:1.xx
docker run -it --name golang-1.xx自定义名称 golang:1.xx
进入到容器中(默认是基于ubuntu的镜像)
(如果没有vi/vim)切换源，装置vim
mv /etc/apt/sources.list /etc/apt/sources.list.bakecho "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free" >/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster-updates main contrib non-free" >>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/debian/ buster-backports main contrib non-free" >>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/debian-security buster/updates main contrib non-free" >>/etc/apt/sources.listapt-get updateapt-get install -y vim这种形式是万能的，任何版本都能够失去 (然而都是Linux版本的~)
其余计划--brew
但如果想用Mac的以往版本的Go，用Docker形式做不到~
还能够用brew
能够在这里找到所有能够装置的Go版本
(从1.16开始反对m1)
问题解决
切换为Go 1.11.5版本后,IDE会主动报错
y为int32,将其强制转为uint32即可,
i为int,将其强制转为uint即可.
