Question

有人熟悉etcd项目吗？或者我们在谈论这个问题时最好忘记这个项目。问题是

$ build
ln: `gopath/src/github.com/coreos/etcd': cannot overwrite directory

执行构建 shell时内容是：

#!/bin/sh -e

if [ ! -h gopath/src/github.com/coreos/etcd ]; then
    mkdir -p gopath/src/github.com/coreos/
    ln -s ../../../.. gopath/src/github.com/coreos/etcd
fi

export GOBIN=${PWD}/bin
export GOPATH=${PWD}/gopath
export GOFMTPATH="./bench ./config ./discovery ./etcd ./error ./http ./log main.go ./metrics ./mod ./server ./store ./tests"

# Don't surprise user by formatting their codes by stealth
if [ "--fmt" = "$1" ]; then
    gofmt -s -w -l $GOFMTPATH
fi

go install github.com/coreos/etcd
go install github.com/coreos/etcd/bench

一些补充：我的系统是windows 7 我在git bash上运行shell。 问题重现：

step1: open the git bash
step2: git clone git@github.com:coreos/etcd.git
step3: cd etcd
step4: build

Answer 1

如“Git Bash Shell fails to create symbolic links”中所述（因为您在Windows 7上使用git bash中的脚本）

msysGit附带的ln只是试图复制其参数，而不是乱用链接。这是因为链接仅在NTFS文件系统上工作（类型），并且MSYS团队不想重新实现ln。

解决方法是从Bash运行mklink   这也允许您创建Symlink or a Junction。

所以'ln'默认情况下无法正常工作，在Git for Windows附带的旧shell中。

Answer 2

这是解决方案。这是一种解决方法，但由于你是在Windows上，我不会看到另一种方式。

启动命令行，然后使用脚本输入到该目录。应该有一个路径gopath/src/github.com/coreos/（如果没有这样的路径，你必须创建它）。接下来发出一个命令

mklink /D "gopath/src/github.com/coreos/etcd" "../../../../"

接下来，您应该编辑构建脚本以删除具有创建符号链接和目录的行。例如。

#!/bin/sh -e

export GOBIN=${PWD}/bin
export GOPATH=${PWD}/gopath
export GOFMTPATH="./bench ./config ./discovery ./etcd ./error ./http ./log main.go ./metrics ./mod ./server ./store ./tests"

# Don't surprise user by formatting their codes by stealth
if [ "--fmt" = "$1" ]; then
    gofmt -s -w -l $GOFMTPATH
fi

go install github.com/coreos/etcd
go install github.com/coreos/etcd/bench

注意，我刚刚删除了4行代码。接下来，您运行脚本，这应该可以。

Answer 3

您不应该使用git clone和build sh脚本。使用go get命令。例如，在Windows 7上，

Microsoft Windows [Version 6.1.7601]

'ln'脚本有些错误
