为idn-ruby进行捆绑安装时出错

Question

我的应用程序中有twitter文本宝石。

当我进行捆绑安装时，我会得到以下错误。

需要优先解决这个问题。

我还访问了github页面https://github.com/twitter/twitter-text/issues/225

但在那里找不到解决办法。

我试图使用下面的行直接安装，但也得到了同样的错误。

gem install idn-ruby -v '0.1.0'

错误

Could not create Makefile due to some reason, probably lack of necessary

To see why this extension failed to compile, please check the mkmf.log which can be found here:

extconf failed, exit code 1

Gem files will remain installed in /home/inuscg/.rvm/gems/ruby-2.3.0@idt-two/gems/idn-ruby-0.1.0 for inspection.

An error occurred while installing idn-ruby (0.1.0), and Bundler cannot continue.
Make sure that `gem install idn-ruby -v '0.1.0'` succeeds before bundling.

In Gemfile:
  twitter-text was resolved to 2.1.0, which depends on
    idn-ruby

提前谢谢你

Answer 1

根据日志中的错误显示，ERROR: could not find idn library!。安装twitter文本需要idn库。尝试先安装它，然后安装创业板。试着

sudo apt-get install libldap2-dev
sudo apt-get install libidn11-dev

希望这能解决你的问题。

对于mac：

brew install libidn

Answer 2

在Mac电脑上，你可以：

$ brew install libidn

Answer 3

如果您使用的是Mac，那么下面是如何安装libidn

$ brew install libidn
