如何使setuptools安装不在PyPI上的软件包？ [英] How can I make setuptools install a package that's not on PyPI?

问题描述

我刚刚开始使用setuptools和virtualenv。我的软件包需要最新的python-gearman，该工具仅可从GitHub获得。 PyPI上的python-gearman版本是旧版本。 Github的源代码是setuptools兼容的，即具有setup.py等。是否可以通过一种方法来使setuptools下载并安装新版本，而不是在PyPI上查找并安装旧版本？

I've just started working with setuptools and virtualenv. My package requires the latest python-gearman that is only available from GitHub. The python-gearman version that's on PyPI is an old one. The Github source is setuptools-compatible, i.e. has setup.py, etc. Is there a way to make setuptools download and install the new version instead of looking for it on PyPI and installing the old one?

仅供参考，新的python-gearman是 http://github.com/mtai/ python-gearman

FYI, the new python-gearman is http://github.com/mtai/python-gearman

推荐答案

关键是要告诉easy_install软件包可以在哪里下载。在这种特殊情况下，可以在以下网址找到它： http://github.com/mtai / python-gearman / tarball / master 。但是，该链接本身不起作用，因为easy_install无法仅通过查看URL来知道它将会得到什么。

The key is to tell easy_install where the package can be downloaded. In this particular case, it can be found at the url http://github.com/mtai/python-gearman/tarball/master. However, that link by itself won't work, because easy_install can't tell just by looking at the URL what it's going to get.

通过将其更改为 http://github.com/mtai/python-gearman/tarball /master#egg=gearman-2.0.0beta 相反，easy_install将能够识别软件包名称及其版本。

By changing it to http://github.com/mtai/python-gearman/tarball/master#egg=gearman-2.0.0beta instead, easy_install will be able to identify the package name and its version.

最后一步是添加包的dependency_links的URL，例如：

The final step is to add the URL to your package's dependency_links, e.g.:

setup(
   ...
   dependency_links = ['http://github.com/mtai/python-gearman/tarball/master#egg=gearman-2.0.0beta']
)

现在，在安装您的软件包时，easy_install将发现有一个可从该URL下载的 gearman 2.0.0beta，并乐于在PyPI上选择它，如果在依赖项中指定 gearman> = 2.0.0beta。

Now, when YOUR package is being installed, easy_install will discover that there is a "gearman 2.0.0beta" available for download from that URL, and happily pick it over the one on PyPI, if you specify "gearman>=2.0.0beta" in your dependencies..

（通常，这种方式要做的就是在一个人的PyPI页面上包含指向可下载源的链接；在这种情况下，如果Gearman软件包的作者包含了上述链接，那么您已经设置好了。通常，人们用'myproject-dev'标记开发版本，然后人们使用'myproject> = somever，== dev'的要求，因此，如果没有更高版本的软件包，easy_install将尝试检查或下载该版本。）

(Normally, the way this sort of thing is done is to include a link on one's PyPI page to the downloadable source; in this case, if the author of the gearman package had included a link like the above, you'd be already set. Typically, people mark the development version with 'myproject-dev' and then people use a requirement of 'myproject>=somever,==dev', so that if there isn't a package of somever or higher, easy_install will try to check out or download the release.)

使用时，您需要指定-process-dependency-links pip 。请注意，依赖项链接处理已被弃用，并将在以后的版本中删除。

You'll need to specify --process-dependency-links when using pip. Note that dependency links processing has been deprecated and will be removed in a future release.
