无法构建开源项目

Question

我想为一个用go它构建的OSS项目做贡献,但我很难编译它.看起来好像我错过了一些明显的东西.

我认为这个问题与go我的计算机上安装的方式有关,而不是与项目本身有关,因此我在StackOverflow上发布它,而不是项目的"问题"部分.

以下是我正在做的事情.

1. 我安装go使用homebrew:

   $ brew install go
   Updating Homebrew...
   ==> Auto-updated Homebrew!
   Updated 1 tap (homebrew/core).
   ==> Updated Formulae
   libebml
   
   ==> Downloading https://homebrew.bintray.com/bottles/go-1.8.3.sierra.bottle.tar.gz
   Already downloaded: /Users/gmile/Library/Caches/Homebrew/go-1.8.3.sierra.bottle.tar.gz
   ==> Pouring go-1.8.3.sierra.bottle.tar.gz
   ==> Caveats
   A valid GOPATH is required to use the `go get` command.
   If $GOPATH is not specified, $HOME/go will be used by default:
     https://golang.org/doc/code.html#GOPATH
   
   You may wish to add the GOROOT-based install location to your PATH:
     export PATH=$PATH:/usr/local/opt/go/libexec/bin
   ==> Summary
     /usr/local/Cellar/go/1.8.3: 7,035 files, 282.0MB
   $
   

2. 然后我克隆了回购:

   $ hub clone lucapette/fakedata
   

3. 我跑make setup(按指令),最初没有成功完成:

   $ make setup
   go get -u github.com/alecthomas/gometalinter
   gometalinter --install
   make: gometalinter: No such file or directory
   make: *** [setup] Error 1
   $
   

   我想这是因为gometalinter我无处可去$PATH,所以加了它(我用的是鱼壳):

   $ set fish_user_paths /Users/gmile/go/bin
   

4. 跑步make setup似乎现在已经成功了.这是输出:

   $ make setup
   go get -u github.com/alecthomas/gometalinter
   gometalinter --install
   Installing:
     aligncheck
     deadcode
     dupl
     errcheck
     gas
     goconst
     gocyclo
     goimports
     golint
     gosimple
     gotype
     ineffassign
     interfacer
     lll
     megacheck
     misspell
     safesql
     staticcheck
     structcheck
     unconvert
     unparam
     unused
     varcheck
   $
   

5. 运行make build失败:

   $ make build
   go build
   main.go:11:2: cannot find package"github.com/lucapette/fakedata/pkg/fakedata" in any of:
           /usr/local/Cellar/go/1.8.3/libexec/src/github.com/lucapette/fakedata/pkg/fakedata (from $GOROOT)
           /Users/gmile/go/src/github.com/lucapette/fakedata/pkg/fakedata (from $GOPATH)
   main.go:12:2: cannot find package "github.com/spf13/pflag" in any of:
           /usr/local/Cellar/go/1.8.3/libexec/src/github.com/spf13/pflag (from $GOROOT)
           /Users/gmile/go/src/github.com/spf13/pflag (from $GOPATH)
   make: *** [build] Error 1
   $
   

因此,任何贡献指南都是不完整的,或者我遗漏了一些关于安装和管理go包的明显事实.

Answer 1

克隆源代码时的路径必须在golang PATH上: /home/gujarat/golang/src/github.com/lucapette/fakedata

你可以看到我的golang路径是:/home/gujarat/golang/.您还可以输入以下命令在终端中打印golang路径:$GOPATH.

并且git clone应该在下面的路径中如下:src/github.com/lucapette/.

cd $GOPATH/src/github.com/
mkdir lucaptte
cd lucapette
git clone https://github.com/lucapette/fakedata.git

当您运行make触发go build此命令的命令时,将查看$GOPATH您和您的$GOROOT文件夹.
