How to apply a git patch when given a pull number
提问by Homunculus Reticulli
I downloaded a trunk version of a codebase from git, and there are build errors. Aparently a patch is now available, and I received an email :
我从 git 下载了一个代码库的主干版本，并且存在构建错误。显然现在有一个补丁可用，我收到了一封电子邮件：
see https://github.com/JustinTulloss/zeromq.node/pull/47 for patch
见 https://github.com/JustinTulloss/zeromq.node/pull/47 补丁
I am new to git so I'm not quite sure what to do with this 'patch' especially, since the page looks more like a discussion thread.
我是 git 的新手，所以我不太确定如何处理这个“补丁”，特别是，因为该页面看起来更像是一个讨论线程。
Does anyone know how I can obtain/apply this patch to my locally cloned git repository?
有谁知道我如何获取/将此补丁应用于我本地克隆的 git 存储库？

Save the patch somewhere. If you're using linux you can use curl:
将补丁保存在某处。如果您使用的是 linux，则可以使用 curl：
curl -L https://github.com/JustinTulloss/zeromq.node/pull/47.patch > /tmp/47.patch
To apply the patch use git apply. You can see if the patch will apply cleanly with the checkoption. Change to your git directory and run:
要应用补丁，请使用git apply. 您可以使用该check选项查看补丁是否可以干净地应用。切换到您的 git 目录并运行：
git apply --check /tmp/47.patch
If it looks like you want to apply the patch remove the check option
如果看起来您想应用补丁，请删除检查选项
git apply /tmp/47.patch

Just add a .patchat the end to get the patch:
只需.patch在末尾添加一个即可获得补丁：
https://github.com/JustinTulloss/zeromq.node/pull/47.patch
https://github.com/JustinTulloss/zeromq.node/pull/47.patch
You can do something like below:
您可以执行以下操作：
$ git checkout master
$ curl http://github.com/JustinTulloss/zeromq.node/pull/47.patch | git am
$ git push origin master

The rule seems recently changed.
规则似乎最近发生了变化。
Previously we took a PR and add a .patchat the end to get the patch
之前我们拿了一个 PR 并.patch在最后添加一个以获得补丁
http://github.com/[group]/[project]/pull/30583.patch
But now the link is redirect(301) to
但现在链接重定向（301）到
https://patch-diff.githubusercontent.com/raw/[group]/[project]/pull/30583.patch
So if you use curl, you could pipe with git applycommand to apply a git patch from the Pull Request
因此，如果您使用curl，则可以使用git apply命令通过管道从拉取请求中应用 git 补丁
curl https://patch-diff.githubusercontent.com/raw/[group]/[project]/pull/30583.patch | git apply
If the patch is not right for you now, use git apply -Rcommand to rollback the change.
如果补丁现在不适合您，请使用git apply -R命令回滚更改。

To let git download pull request 47 and patch it into mylocalbranchlocally, run:
要让 git 下载 pull request 47 并将其修补到mylocalbranch本地，请运行：
git checkout -b mylocalbranch
git pull origin pull/47/head
If the pull request isn't on the origin repo, run
如果拉取请求不在原始存储库中，请运行
git remote add patchremote https://github.com/JustinTulloss/zeromq.node
git pull patchremote pull/47/head

git fetch -q origin +refs/pull/47/merge:
git checkout -qf FETCH_HEAD
