无法将函数用作Go中的类型

我正在尝试从源代码运行以太坊（我想用调试器跟踪执行），但在编译时遇到问题。这就是我得到的错误：

[niko@localhost sources]$  go run github.com/ethereum/go-ethereum/cmd/geth/main.go github.com/ethereum/go-ethereum/cmd/geth/config.go github.com/ethereum/go-ethereum/cmd/geth/chaincmd.go github.com/ethereum/go-ethereum/cmd/geth/monitorcmd.go github.com/ethereum/go-ethereum/cmd/geth/accountcmd.go gopkg.in/urfave/cli.v1  --verbosity 5 --ipcdisable --port 40401 --rpc --rpcport 9101 --pprof --datadir=/home/niko/saved-niko-home/myeth/ --networkid=15 console

[niko@localhost sources]$ 

如您所见，它抱怨：

func(*"gopkg.in/urfave/cli.v1".Context)

不同于：

func(*"github.com/ethereum/go-ethereum/vendor/gopkg.in/urfave/cli.v1".Context) 

但是，它是相同的，因为我手动将它复制到/home/niko/go，所有我的

go

包都位于那里：

[niko@localhost sources]$ find /home/niko/go -iname "*cli.v1*"
/home/niko/go/src/gopkg.in/urfave/cli.v1
/home/niko/go/pkg/linux_amd64/gopkg.in/urfave/cli.v1.a
[niko@localhost sources]$ 

它就在我的路上

那么，如何避免这个错误，如何告诉Go这个包是好的呢？

github.com/ethereum/Go ethereum/vendor/gopkg.in/urfave/cli.v1

gopkg.in/urfave/cli.v1

都是不同的导入路径包，无论内容如何，都被认为是不同的

这里的问题是，您的程序不知何故从不同的位置加载了两次，导致出现您提供的错误消息

我不太清楚您使用的

go-run

命令行，我宁愿这样做

go run github.com/ethereum/go-ethereum/cmd/geth/*go --verbosity 5 --ipcdisable --port 40401 --rpc --rpcport 9101 --pprof --datadir=/home/niko/saved-niko-home/myeth/ --networkid=15 console

除非你想入侵以太坊，否则我认为没有理由把它的依赖项复制到你的gopath。 当他们供应商提供其依赖项时（即：他们将其依赖项复制到供应商文件夹中），ref:您真的应该使用这些

关于你的道路

/home/niko/sources/github.com/ethereum/go-ethereum/build/_-workspace/：/home/niko/sources/github.com/ethereum/go-ethereum/vendor:/home/niko/go

我觉得不太好

如果

GOPATH=/home/niko/sources/

，那么

tree $GOPATH -L 1
/home/niko/sources/
├── bin
├── pkg
└── src

3 directories, 0 files

和

ls-al$GOPATH/src/github.com/ethereum/go-ethereum

应该是正确的

另请参见

go-env

，虽然路径不同，但它并不相同。这使他们different@Flimzy代码所在的路径属于Go的标准位置，可重用包应该位于该位置，即GOPATH目录中，这无关紧要。代码期望它被出售。因此，如果它不在供应商目录中，则是错误的。@Flimzy我如何指定文件的确切位置？因为我已将它们从一个地方复制到另一个地方几个小时了，但它不起作用。你根本不应该复制/移动它们。供应商提供的文件通常应随源程序包一起提供。是的，您完全正确，函数定义了两次，因为我在命令行中手动提供源文件。但是，如果我省略它们，我会遇到另一个问题，发布在这里：在src、pkg目录中列出源代码之后，它就工作了。谢谢
