今天安装gin框架，首先下载gin，命令如下：
go get github.com/mattn/go-sqlite3
结果报错:
package golang.org/x/net/context: unrecognized import path "golang.org/x/net/context" (https fetch: Get https://golang.org/x/net/context?go-get=1: dial tcp 216.239.37.1:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
操作的办法就是：
1 2 3 4 | $mkdir -p $GOPATH/src/golang.org/x/$cd $GOPATH/src/golang.org/x/$git clone https://github.com/golang/net.git net $go install net |
安装了这个net包，然后再去安装go-sqlite3，就安装成功了。
go get报错unrecognized import path “golang.org/x/net/context”…
