D:\Project\Go\GinDemo\15gin_file>go get -u gorm.io/driver/sqlite
go: downloading gorm.io/driver/sqlite v1.1.4
go: downloading github.com/mattn/go-sqlite3 v1.14.5

# github.com/mattn/go-sqlite3
cgo: exec gcc: exec: "gcc": executable file not found in %PATH%

解决

可以在MinGW-w64下载离线安装包。

下载了x86_64-posix-sjlj的压缩包，如图所示，然后解压缩便得到了mingw64。

直接将bin路径添加到环境变量中即可。

  • 在系统变量中，新增：GCC_HOME:C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw643， LIBRARY_PATH:%GCC_HOME%\lib， %GCC_HOME%\lib:%GCC_HOME%\include

  • path中新增：%GCC_HOME%\bin
