Question

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

[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]$ 
[niko@localhost sources]$ echo $GOPATH
/home/niko/sources/github.com/ethereum/go-ethereum/build/_workspace/:/home/niko/sources/github.com/ethereum/go-ethereum/vendor:/home/niko/go
[niko@localhost sources]$

你可以看到它抱怨：

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

与：

不同

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

然而，它是相同的，因为我手动将其复制到/ home / niko / go所有Go包所在的位置：

[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]$

它在我的GOPATH中

那么，我该如何解决这个错误，如何告诉Go这个包是好的呢？

Answer 1

github.com/ethereum/go-ethereum/vendor/gopkg.in/urfave/cli.v1

gopkg.in/urfave/cli.v1

是不同的导入路径包，无论内容如何，都被认为是不同的。

这里的问题是你的程序以某种方式从不同的位置加载两次，导致你提供的那种错误信息。

我对你使用的go run命令行不太清楚，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

除非您想破解以太坊，否则我认为没有理由将其依赖项复制到您的gopath。当他们出售他们的依赖关系（IE：他们将他们的依赖关系复制到vendor文件夹中）ref：https://github.com/ethereum/go-ethereum/tree/master/vendor你真的应该使用它们。

关于你的gopath

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

对我来说看起来不太好。

如果是GOPATH=/home/niko/sources/，那么，

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

3 directories, 0 files

ls -al $GOPATH/src/github.com/ethereum/go-ethereum应该是正确的。

另见go env。

不能在Go中使用函数作为类型
