Default Git master branch checkout in Travis CI build when using go get
问题
我在尝试使用Travis CI构建时遇到了一些困难。
我正在使用Parse(.com)作为后端，并找到了一个使用Travis进行构建和部署的示例这里。然而，尽管我尽力进行了设置，但我现在遇到了一个Google无法解决的问题。
我从Travis CI构建日志中得到了以下错误信息：
....
$ mkdir -p "$TRAVIS_BUILD_DIR/gosrc"
$ mkdir -p "$TRAVIS_BUILD_DIR/static"
$ curl -s https://www.parse.com/downloads/cloud_code/installer.sh | sudo /bin/bash
$ go get -v github.com/xxxxx/xxxxxxx
github.com/xxxxxx/xxxxxx (download)
cd /home/travis/build/xxxxx/xxxxx/gosrc/src/github.com/xxxxxx/xxxxxx; git checkout master
error: pathspec 'master' did not match any file(s) known to git.
package github.com/xxxxx/xxxxxx: exit status 1
The command "go get -v github.com/xxxxxx/xxxxxx" failed and exited with 1 during .
Your build has been stopped.
这是我的.travis.yml文件中的安装部分：
install:
- mkdir -p "$TRAVIS_BUILD_DIR/gosrc"
- mkdir -p "$TRAVIS_BUILD_DIR/static"
- curl -s https://www.parse.com/downloads/cloud_code/installer.sh | sudo /bin/bash
- go get -v github.com/xxxxxx/xxxxxxx
我的问题是：在执行go get {git repo}时，是否可以指定它应该检出哪个分支？这样它就不会默认检出master分支。如果不能，是否有更好的方法来做到这一点？
注意：我在我的存储库中没有主分支，因为我一段时间前将其删除了，因为我没有使用它。我需要添加一个主分支才能使其工作吗？
如果问题不清楚或缺少必要的信息，请告诉我。
非常感谢任何帮助！

I'm having some difficulties getting my first attempts at an Travis CI build working.
I'm using Parse(.com) as a backend and have then found an example of using Travis for build and deployment here. However having tried to set it up as best I could I now gotten to a problem which Google can't help with.
I'm getting this error from the Travis CI build log.
....
$ mkdir -p "$TRAVIS_BUILD_DIR/gosrc"
$ mkdir -p "$TRAVIS_BUILD_DIR/static"
$ curl -s https://www.parse.com/downloads/cloud_code/installer.sh | sudo /bin/bash

github.com/xxxxxx/xxxxxx (download)
cd /home/travis/build/xxxxx/xxxxx/gosrc/src/github.com/xxxxxx/xxxxxx; git checkout master
error: pathspec 'master' did not match any file(s) known to git.
package github.com/xxxxx/xxxxxx: exit status 1
The command "go get -v github.com/xxxxxx/xxxxxx" failed and exited with 1 during .
Your build has been stopped.
This is my install section of the .travis.yml file
install:
- mkdir -p "$TRAVIS_BUILD_DIR/gosrc"
- mkdir -p "$TRAVIS_BUILD_DIR/static"
- curl -s https://www.parse.com/downloads/cloud_code/installer.sh | sudo /bin/bash
- go get -v github.com/xxxxxx/xxxxxxx
My question is: Can you, when conducting a go get {git repo}, specify which branch it's supposed to checkout? So it doesn't default to master. If not is there a better way of doing this?
Note: I don't have a master branch in my repository, having removed it some time ago because I didn't use it. Do I need to add one for this to work?
Please let me know if the question is unclear or if it's missing some needed information.
Thankful for any help!

简短回答是不可以，你不能使用go get指定分支或标签。然而，如果你检查一下go工具的源代码，你会发现在克隆时它实际上也没有指定master。它只是克隆了整个仓库。这可能是一个git/GitHub的问题。
你可以尝试在终端中克隆该仓库到其他位置，看看是否会报错找不到master分支。仓库有一个设置，用于指定默认分支，如果它仍然默认为master，即使你没有该分支，你将会看到错误。我通过创建一个没有master分支的GitHub仓库来复现了这个问题。我通过进入GitHub仓库的设置并指定默认分支来解决了这个问题。
注意：如果你的本地仓库处于分离头状态，go get命令将会指定master分支。从输出来看，我不认为这是发生在这里的情况。

The short answer is that No, you can't specify a branch or tag with go get. However, if you inspect the source of the go tool you will see that it doesn't really specify master either when it's doing a clone. It just clones the repo. This is probably really a git/GitHub issue.
Can you open a terminal and just clone that repo to some other location? Does it give you a complaint about not having the master branch? Repositories have a setting for which branch should be the default and if it's still defaulting to master even though you don't have one then you'll see the error. I reproduced this by making a GitHub repo without a master branch. I was able to fix it by going into my GitHub repo settings and specifying the default branch.
Note: The go get command will specify the master branch if your local repo is in a detached head state. Looking at the output I don't think that's what's happening here.
