Go 常见问题
Go常见问题
问题: go.mod file not found
现象
go.mod file not found in current directory or any parent directory.
原因
Go1.16之后引入GoMod, 不需要基于GoPath进行包管理
在创建新项目的时候需要初始化模块
解决
# 初始化模块
go mod init example/hello
问题: GoLand无法选择Go版本
现象
The selected directory is not a valid home for Go SDK
原因
Goland是通过src内的源码文件读取版本信息的.
解决
打开文件:
${GOROOT}/src/runtime/internal/sys/zversion.go
添加版本号如下:
const TheVersion = `go1.20`
命令行:
echo -e "\nconst TheVersion = \`$(cat ${GOROOT}/VERSION)\`" >> ${GOROOT}/src/runtime/internal/sys/zversion.go
问题: Goland不显示代码提示
现象
原因
加载的GoRoot的GO环境中, 没有设置代理
解决
IDE -> File -> Settings -> Go -> GoModules
勾选: Enable Go modules integration
GOPROXY=https://goproxy.io
即可.
问题: Go项目编译时随机崩溃, 0xc0000005 0x0 0x1e1c5a53150 0x7ffce8a8ce20
现象
IDE或CMD编译Go项目的时候, 会有一定概率随机出现内存错误.
日志如下:

main.main()
原因
该问题为因Windows系统环境异常从而引起, 导致随机崩溃的问题.
使用最简单的HelloWorld代码测试, 如下,
package main
func main() {
print("Hello,World")
}
也同样会引起该类似的错误, 唯一的区别是该随机触发的概率有所降低.(?代码量越多, 则越容易触发)
推断可能是因为安全软件引起的环境问题.
- 可能影响的防火墙类/ 安全卫士类的 软件:
- Webroot SecureAnywhere
- XXX安全助手: ×, 卸载后再未出现过类似问题
解决
排查对应的安全助手或防火墙软件, 卸载即可.
