如何在 Heroku 上正确安装 PyICU？

Question

我正在尝试在 Heroku 上部署我的 Python 应用程序，但没有成功。 PyICU package 似乎出现了问题，我不确定如何纠正。 我已经确认这是我部署的唯一问题； 当我从需求文件中删除PyICU时，一切正常。 但当然，没有它我的网站就无法工作。

谁能指导我如何在 Heroku 上正确安装这个 package？ 我尝试了各种方法，包括下载 .whl 文件，然后将其添加到我的需求文件中，但随后出现另一个错误：

ERROR: PyICU-2.7.3-cp38-cp38m-win_amd64.whl is not a supported wheel on this platform. 我不明白为什么 - 它是正确的 Python 和操作系统版本。

如果有人能推荐一个修复方法，我将非常感激，谢谢。 我知道 PyICU 即使在本地也不是最容易安装的，但是我该如何告诉 Heroku 怎么做呢？

编辑：我尝试为 ICU 添加自定义构建包： https://github.com/generalassembly/heroku-icu-buildpack

它似乎运行起来有点不同，但仍然会出现关于语言环境的错误以及以下错误：

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

Answer 1

我自己没有尝试过，但是可以使用heroku-buildpack-apt来安装 PyICU，使用他们的 Debian安装方法。

否则，您的轮子需要与服务器操作系统的版本相同，而不是您的开发机器的操作系统。 您可以尝试使用此 StackOverflow 答案中的技术在 Heroku 测功机内部构建轮子。

我没有测试这些方法的存储库，所以我不确定它们的效果如何。 如果您尝试一下，我将很乐意更新此答案。

Answer 2

你为什么使用 windows 轮（ PyICU-2.7.3-cp38-cp38m-win_amd64.whl ）？ 你可能需要一个manylinux轮子。

你也可以试试pyicu-binary package。
