帶有所有補丁的 OS X Yosemite。安裝好了brew install go --cross-compile-common創建 ~/work，設置環境如下：export GOPATH=$HOME/workexport GOROOT='/usr/local/Cellar/go/1.6'export PATH=$PATH:$GOROOT/bin現在嘗試添加一個包給我一個錯誤：go get golang.org/x/tools/cmd/godocpackage archive/zip: unrecognized import path "archive/zip" (import path does not begin with hostname)package bytes: unrecognized import path "bytes" (import path does not begin with hostname)package encoding/json: unrecognized import path "encoding/json" (import path does not begin with hostname)package encoding/xml: unrecognized import path "encoding/xml" (import path does not begin with hostname)package errors: unrecognized import path "errors" (import path does not begin with hostname)package expvar: unrecognized import path "expvar" (import path does not begin with hostname)package flag: unrecognized import path "flag" (import path does not begin with hostname)package fmt: unrecognized import path "fmt" (import path does not begin with hostname)...Go 是否支持 OS X 10.10？我在這里錯過了什么？
