gocode安装失败

在/usr/local/go/bin目录下手动创建gocode目录就可以解决

wangdongyang@wdy:/usr/local$ go get -u github.com/nsf/gocode
go install github.com/nsf/gocode: open /usr/local/go/bin/gocode: permission denied
wangdongyang@wdy:/usr/local$ ls -la /usr/local/go/bin/

open dlv安装失败

go install github.com/derekparker/delve/cmd/dlv: open /usr/local/go/bin/dlv: permission denied

同样在/usr/local/go/bin目录下手动创建dlv目录就可以解决
