> golang报错：unrecognized import path “[golang.org/x/tour][golang.org_x_tour]”

由于`golang.org`官网无法顺利打开，国内的用户可以使用`golang.google.cn`镜像网站来查看一些文档等。

但是在安装`x/tour`， `x/net`等扩展包的时候，就无能为力了。

除了使用VPN以外，可以使用手动下载代码的方式，下边来介绍一下怎么手动解决的。

### 手动安装非预装扩展包: ###

golang 官方在 `github` 上建立了一个镜像库，直接从github下载镜像代码，放入`GOPATH`目录下即可。

直接通过 `go get` 安装，报错:

$ go get golang.org/x/tour
    package golang.org/x/tour: 
     unrecognized import path "golang.org/x/tour" 
     (https fetch: Get https://golang.org/x/tour?go-get=1: 
     	dial tcp 216.239.37.1:443: i/o timeout)
    
    $ go get -u golang.org/x/blog
    package golang.org/x/blog: 
     unrecognized import path "golang.org/x/blog" 
     (https fetch: Get https://golang.org/x/blog?go-get=1: 
     	dial tcp 216.239.37.1:443: i/o timeout)

切换成国内可以打开的 `golang.google.cn` 网址也不行:

$ go get golang.google.cn/x/tour
    package golang.google.cn/x/tour: 
     unrecognized import path "golang.google.cn/x/tour" 
      (parse https://golang.google.cn/x/tour?go-get=1: 
      	 no go-import meta tags (meta tag golang.org/x/tour did not match 
      	 	import path golang.google.cn/x/tour))

查看$GOPATH环境变量:

如果没有设置 `$GOPATH` 环境变量，请参考 “如何设置go环境变量GOPATH？” 。

$ echo $GOPATH 
    /Users/wangtom/development/gopath
    $ cd $GOPATH  
    $ pwd
    /Users/wangtom/development/gopath

首先创建好 `src/golang.org/x/` 目录:

$ mkdir -p src/golang.org/x/

拉取各个模块的代码:

比如拉取 `x/net` 代码，直接执行:

$ git clone https://github.com/golang/net.git

可以将Go的各个子包都给下载下来:

$ git clone https://github.com/golang/tour.git
    $ git clone https://github.com/golang/net.git
    $ git clone https://github.com/golang/blog.git
    $ git clone https://github.com/golang/sync.git
    $ git clone https://github.com/golang/tools.git
    $ git clone https://github.com/golang/lint.git
    // ...

每个包的名称如下:

benchmarks — benchmarks to measure Go as it is developed.
    blog — blog.golang.org's implementation.
    build — build.golang.org's implementation.
    crypto — additional cryptography packages.
    debug — an experimental debugger for Go.
    image — additional imaging packages.
    mobile — experimental support for Go on mobile platforms.
    net — additional networking packages.
    perf — packages and tools for performance measurement, storage, and analysis.
    review — a tool for working with Gerrit code reviews.
    sync — additional concurrency primitives.
    sys — packages for making system calls.
    text — packages for working with text.
    time — additional time packages.
    tools — godoc, goimports, gorename, and other tools.
    tour — tour.golang.org's implementation.
    exp — experimental and deprecated packages (may change without warning).

### VSCode 安装扩展报错: ###

在 VSCode 中安装go扩展 `Go for Visual Studio Code` 报错:

gocode:
    Error: Command failed: /usr/local/go/bin/go get -u -v github.com/mdempsky/gocode
    github.com/mdempsky/gocode (download)
    Fetching https://golang.org/x/tools/go/gcexportdata?go-get=1
    https fetch failed: Get https://golang.org/x/tools/go/gcexportdata?go-get=1: dial tcp 216.239.37.1:443: i/o timeout
    package golang.org/x/tools/go/gcexportdata: unrecognized import path "golang.org/x/tools/go/gcexportdata" (https fetch: Get https://golang.org/x/tools/go/gcexportdata?go-get=1: dial tcp 216.239.37.1:443: i/o timeout)

问题原因: 该扩展使用了`x/tools`,`x/lint`等go语言非预装的扩展包，需要先安装.

解决办法: 使用上边介绍的方法，把相关依赖包下载下来即可。
