如何在Requirements.txt中声明直接的github源

本文翻译自：How to state in requirements.txt a direct github source

I've installed a library using the command 我已经使用以下命令安装了一个库

pip install git+git://github.com/mozilla/elasticutils.git

which installs it directly from a Github repository. 直接从Github存储库安装它。 This works fine and I want to have that dependency in my requirements.txt . 这工作正常，我想在我的requirements.txt具有该依赖关系。 I've looked at other tickets like this but that didn't solve my problem. 我看其他的票像这样但这并没有解决我的问题。 If I put something like 如果我把像

-f git+git://github.com/mozilla/elasticutils.git
elasticutils==0.7.dev

in the requirements.txt file, a pip install -r requirements.txt results in the following output: 在requirements.txt文件中， pip install -r requirements.txt导致以下输出：

Downloading/unpacking elasticutils==0.7.dev (from -r requirements.txt (line 20))
  Could not find a version that satisfies the requirement elasticutils==0.7.dev (from -r requirements.txt (line 20)) (from versions: )
No distributions matching the version for elasticutils==0.7.dev (from -r requirements.txt (line 20))

The documentation of the requirements file does not mention links using the git+git protocol specifier, so maybe this is just not supported. 需求文件的文档没有提及使用git+git协议说明符的链接，因此也许只是不支持。

Does anybody have a solution for my problem? 有人能解决我的问题吗？

“Editable” packages syntax can be used in requirements.txt to import packages from a variety of VCS (git, hg, bzr, svn) : “可编辑”包语法可被用requirements.txt到从各种导入包VCS（GIT，HG，BZR，SVN） ：

-e git://github.com/mozilla/elasticutils.git#egg=elasticutils

Also, it is possible to point to particular commit: 另外，可以指向特定的提交：

-e git://github.com/mozilla/elasticutils.git@000b14389171a9f0d7d713466b32bc649b0bed8e#egg=elasticutils

First, install with git+git or git+https , in any way you know. 首先，以您知道的任何方式使用git+git或git+https安装。 Example of installing kronok 's branch of the brabeion project: 安装的例子kronok的的的分支brabeion项目：

pip install -e git+https://github.com/kronok/brabeion.git@12efe6aa06b85ae5ff725d3033e38f624e0a616f#egg=brabeion

Second, use pip freeze > requirements.txt to get the right thing in your requirements.txt . 其次，使用pip freeze > requirements.txt在您的requirements.txt获得正确的内容。 In this case, you will get 在这种情况下，您将获得

-e git+https://github.com/kronok/brabeion.git@12efe6aa06b85ae5ff725d3033e38f624e0a616f#egg=brabeion-master

Third, test the result: 三，测试结果：

pip uninstall brabeion
pip install -r requirements.txt

Since pip v1.5 , (released Jan 1 2014: CHANGELOG , PR ) you may also specify a subdirectory of a git repo to contain your module. 从pip v1.5 （2014年1月1日发布： CHANGELOG ， PR ），您还可以指定git repo的子目录来包含您的模块。 The syntax looks like this: 语法如下所示：

pip install -e git+https://git.repo/some_repo.git#egg=my_subdir_pkg&subdirectory=my_subdir_pkg # install a python package from a repo subdirectory

Note: As a pip module author, ideally you'd probably want to publish your module in it's own top-level repo if you can. 注意：作为pip模块的作者，如果可能的话，理想情况下，您可能希望将模块发布到它自己的顶级仓库中。 Yet this feature is helpful for some pre-existing repos that contain python modules in subdirectories. 但是，此功能对于某些子目录中包含python模块的现有存储库很有帮助。 You might be forced to install them this way if they are not published to pypi too. 如果它们也没有发布到pypi，则可能会被迫以这种方式安装它们。

requirements.txt allows the following ways of specifying a dependency on a package in a git repository as of pip 7.0: ¹ requirements.txt允许通过以下方式在git pip 7.0及更高版本中指定对git存储库中软件包的依赖关系： ¹

[-e] git+git://git.myproject.org/SomeProject#egg=SomeProject
[-e] git+https://git.myproject.org/SomeProject#egg=SomeProject
[-e] git+ssh://git.myproject.org/SomeProject#egg=SomeProject
-e [email protected]:SomeProject#egg=SomeProject

For Github that means you can do (notice the omitted -e ): 对于Github，这意味着您可以执行此操作（注意省略的-e ）：

git+git://github.com/mozilla/elasticutils.git#egg=elasticutils

Why the extra answer? 为什么要额外回答？
I got somewhat confused by the -e flag in the other answers so here's my clarification: 在其他答案中，我对-e标志有些困惑，所以这是我的澄清：

The -e or --editable flag means that the package is installed in /src/SomeProject and thus not in the deeply buried /lib/pythonX.X/site-packages/SomeProject it would otherwise be placed in. ² -e或--editable标志意味着该软件包安装在/src/SomeProject ，因此不会安装在深埋的/lib/pythonX.X/site-packages/SomeProject中。放入^。2

Normally your requirements.txt file would look something like this: 通常，您的requirements.txt文件如下所示：

package-one==1.9.4
package-two==3.7.1
package-three==1.0.1
...

To specify a Github repo, you do not need the package-name== convention. 要指定Github存储库，您不需要package-name==约定。

The examples below update package-two using a GitHub repo. 以下示例使用GitHub存储库更新了第二package-two 。 The text between @ and # denotes the specifics of the package. @和#之间的文本表示软件包的详细信息。

Specify commit hash ( 41b95ec in the context of updated requirements.txt ): 指定提交哈希（在更新的requirements.txt上下文中为41b95ec ）：

package-one==1.9.4
git+git://github.com/path/to/package-two@41b95ec#egg=package-two
package-three==1.0.1

Specify branch name ( master ): 指定分支名称（ master ）：

git+git://github.com/path/to/package-two@master#egg=package-two

Specify tag ( 0.1 ): 指定标签（ 0.1 ）：

git+git://github.com/path/to/[email protected]#egg=package-two

Specify release ( 3.7.1 ): 指定发行版（ 3.7.1 ）：

git+git://github.com/path/to/package-two@releases/tag/v3.7.1#egg=package-two

Note that #egg=package-two is not a comment here, it is to explicitly state the package name 请注意， #egg=package-two在这里不是注释，它是明确声明软件包名称
