英文:
type *gin.Context has no field or method SaveUploadedFile
问题
我的代码在我的电脑上运行正常，但是在将代码移动到Debian服务器后，我在编译时遇到了以下错误：
type *gin.Context has no field or method SaveUploadedFile
我使用了sample gin code来保存文件：
if err := c.SaveUploadedFile(file, file.Filename); err != nil {
c.String(http.StatusBadRequest, fmt.Sprintf("upload file err: %s", err.Error()))
return
}
我已经将服务器上的go升级到1.8.3（与我的桌面上的go版本相同），然后更新了gin，希望能解决这个问题。但是没有成功。
这是我的go env：
root@s1:~# go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/srv/go"
GORACE=""
GOROOT="/usr/local/go"
GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
CXX="g++"
CGO_ENABLED="1"
PKG_CONFIG="pkg-config"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
我还尝试过：
rm -rf $GOPATH/pkg/*
我还尝试了go build -a，但是得到了相同的错误。
英文:
My code works fine on my computer but I get this compile-time error on my server after I moved the code to the Debian server:
type *gin.Context has no field or method SaveUploadedFile
I use sample gin code to save file:
if err := c.SaveUploadedFile(file, file.Filename); err != nil {
c.String(http.StatusBadRequest, fmt.Sprintf("upload file err: %s", err.Error()))
return
}
I have upgraded go to 1.8.3 on the server (to be of the same version as go on my desktop) and updated gin afterwards, hoping to solve the issue. But it did not.
Here is my go env:
root@s1:~# go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"

CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
I have also tried:
rm -rf $GOPATH/pkg/*
I also tried go build -a, but get the same error.

看起来你的服务器正在使用旧版本的gin代码库。我刚刚查看了gin的提交历史。
方法SaveUploadedFile是5天前添加的。所以请在你的服务器上执行以下命令来获取最新的代码库。
go get -u github.com/gin-gonic/gin
然后进行编译。
英文:
It seems your server is using old codebase of gin. Just checked the gin commit history.
The method SaveUploadedFile added 5 days ago. So execute below command to pull the latest codebase on your server.
go get -u github.com/gin-gonic/gin
Then compile it.
