Heroku Aspen上的“错误:未能构建创业板本机扩展”

Question

我尝试克隆一个老Ruby项目，从一个Heroku应用程序到另一个，但我无法让它运行。

我已经设置了一个新的应用程序与aspen 1.8.6堆栈。

但是，当我将代码向上推时(直接从正在工作的应用程序中克隆)，我会得到以下错误：

Counting objects: 465, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (214/214), done.
Writing objects: 100% (465/465), 192.12 KiB | 95 KiB/s, done.

       Provided configuration options:

         Try passing --with-curl-dir or --with-curl-lib and --with-curl-include
         options to extconf.


       Gem files will remain installed in /app/tmp/repo.git/gems_build/gems/patron-0.4.18 for inspection.

任何建议都将不胜感激。

Answer 1

sudo apt安装libcurl3 3-dev

libcurl是一个易于使用的客户端URL传输库，这是一个超出mri ruby要求的库。
