为什么即使我在 Ubuntu 12.10 上安装了 git 1.8.3.2，`git subtree` 也不起作用？

Why is the `git subtree` not working even though I have git 1.8.3.2 installed on Ubuntu 12.10?

I am about to deploy my AngularJS based static site as a Github Page with Yeoman. Step 3 of the deployment instructions tell me to do
我即将使用 Yeoman 将我的基于 AngularJS 的静态站点部署为 Github 页面。部署说明的第 3 步告诉我要做
git subtree push --prefix dist origin gh-pages
git subtree push --prefix dist origin gh-pages
but when I enter that I get
但是当我输入时，我得到
git: 'subtree' is not a git command. See 'git --help'.
git: 'subtree' is not a git command. See 'git --help'.
This SO answer provided me instructionson how to upgrade to the latest git-core and ensure it always get upgraded to the latest stable release.
这个SO answer 为我提供了有关如何升级到最新的 git-core 并确保它始终升级到最新的稳定版本的说明。
sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get install git
After running those commands I did git --versionto make sure I had the latest version and apparently I did since git version 1.8.3.2was the output. Now when I tried running
运行这些命令后，我git --version确保我拥有最新版本，显然我这样做了，因为这git version 1.8.3.2是输出。现在当我尝试跑步时
git subtree push --prefix dist origin gh-pages
git subtree push --prefix dist origin gh-pages
again I still got the same following error
再次我仍然遇到相同的以下错误
git: 'subtree' is not a git command. See 'git --help'.
git: 'subtree' is not a git command. See 'git --help'.
Finally I just restarted Ubuntu 12.10 and tried to run the command again but once again, I got the same error.
最后，我重新启动了 Ubuntu 12.10 并尝试再次运行该命令，但再次出现相同的错误。
How come the git subtreecommand is still not working even though I have upgraded to the current stable release?
git subtree即使我已升级到当前的稳定版本，该命令为什么仍然不起作用？

It doesn't seem to be installed by the default package. This site has some directions: http://engineeredweb.com/blog/how-to-install-git-subtree
它似乎没有被默认包安装。这个网站有一些说明：http: //engineeredweb.com/blog/how-to-install-git-subtree

It actually is installed on Ubuntu but for some reason it's not put anyplace where git can find it. Easiest way is to create a symlink:
它实际上安装在 Ubuntu 上，但由于某种原因，它没有放在 git 可以找到它的任何地方。最简单的方法是创建一个符号链接：
sudo chmod +x /usr/share/doc/git/contrib/subtree/git-subtree.sh
sudo ln -s /usr/share/doc/git/contrib/subtree/git-subtree.sh /usr/lib/git-core/git-subtree
UPDATE 1:looks like a patch has been submittedupstream to fix this but it hasn't yet been merged.
更新 1：看起来上游已提交补丁来解决此问题，但尚未合并。
UPDATE 2:the patch to fix this in Debian has been merged, but since they went the route of a separate git-subtreepackage I don't think this will make it to Ubuntu 12.04. Seems to not be an issue in 14.04 as /usr/lib/git-core/git-subtreeis already created correctly by the gitpackage.
更新 2：在 Debian 中修复此问题的补丁已合并，但由于它们采用单独git-subtree软件包的方式，我认为这不会适用于 Ubuntu 12.04。在 14.04 中似乎不是问题，因为包/usr/lib/git-core/git-subtree已经正确创建了git。

On Fedora, it is available as a separate package:
在 Fedora 上，它作为一个单独的包提供：
dnf install git-subtree
dnf install git-subtree
