如何在Heroku上安装charlock_holmes dependency libicu-dev [英] How to install charlock_holmes dependency libicu-dev on Heroku

问题描述

我在Rails 4应用程序中使用ruby gem charlock_holmes 来检测CSV的字符编码我正在解析，因此 CSV.foreach 不会引发错误。

然而，当我尝试推送到heroku（在Gemfile中使用 gem'charlock_holmes'）我得到以下错误：

 安装charlock_holmes（0.6.9.4）

如何获得 libicu-dev 在Heroku上安装？

解决方案

可悲的是，其他两种解决方案并不适合我），所以我不得不提出我自己的解决方案。该解决方案适用于Ruby 1.9.3，但 hammady 表示它不适用于2.0.0。

我使用了 heroku-buildpack-multi ：

  heroku config：add BUILDPACK_URL = https：//github.com/ddollar/heroku-buildpack-multi.git 
  

使用以下 .buildpacks ：

  https ：//github.com/benjie/heroku-buildpack-apt 
 https://github.com/heroku/heroku-buildpack-ruby 
  

而且 Aptfile ：

  libicu-dev 
  

需要 heroku-buildpack-apt 的我的分支通过 BUNDLE_BUILD__CHARLOCK_HOLMES 变量errer> Heroku的ENV_DIR 。在Gemfile中，您只需像往常一样引用 gem'charlock_holmes'，并且现在对我来说一切正常。

如果有人可以考虑一种不涉及导出 BUNDLE_BUILD__CHARLOCK_HOLMES 的方法，那么请让我知道！

瑞恩的答案对我来说不起作用 - Heroku保释，因为捆绑安装步骤不会3分钟内不提供任何输出。 Silasj的答案引用了 frederick / heroku-buildpack-ruby buildpack其中不再被维护，并且滞后于官方的 heroku-buildpack-ruby ，这是我无法接受的。

I'm using the ruby gem charlock_holmes in a Rails 4 app to detect the character encodings of CSV's that I'm parsing so that CSV.foreach doesn't throw an error.

However, when I try to push to heroku (with gem 'charlock_holmes' in the Gemfile) I get the following error:

How do I get libicu-dev to install on Heroku?

解决方案

Sadly the other two solutions don't work for me (see below), so I had to come up with my own solution. This solution works with Ruby 1.9.3 but hammady says it does not work with 2.0.0.

I used heroku-buildpack-multi:

heroku config:add BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git

With the following .buildpacks:

https://github.com/benjie/heroku-buildpack-apt
https://github.com/heroku/heroku-buildpack-ruby

And this Aptfile:

libicu-dev

My fork of heroku-buildpack-apt is required to export the BUNDLE_BUILD__CHARLOCK_HOLMES variable via Heroku's ENV_DIRs. In the Gemfile you just reference gem 'charlock_holmes' as usual and all works smoothly now for me.

If anyone can think of a way that doesn't involve exporting BUNDLE_BUILD__CHARLOCK_HOLMES then please let me know!

Ryan's answer doesn't work for me - Heroku bails because the bundle install step doesn't offer any output for 3 minutes. Silasj's answer references the frederick/heroku-buildpack-ruby buildpack which is no longer maintained and lags behind the official heroku-buildpack-ruby by quite an amount, which is not acceptable to me.
