无法在Linux Mint中安装遏制宝石

Question

我在安装路边时遇到问题。当我在控制台输入：

sudo gem install curb 

它返回我以下错误：

Fetching: curb-0.8.6.gem (100%) 
Building native extensions. This could take a while... 
ERROR: Error installing curb: 
    ERROR: Failed to build gem native extension. 

     /usr/bin/ruby1.9.1 extconf.rb

*** extconf.rb failed *** 
Could not create Makefile due to some reason, probably lack of 
necessary libraries and/or headers. Check the mkmf.log file for more 
details. You may need configuration options. 

Provided configuration options:

    --with-curllib 
    --without-curllib 
extconf.rb:23:in `<main>': Can't find libcurl or curl/curl.h (RuntimeError) 

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


Gem files will remain installed in /var/lib/gems/1.9.1/gems/curb-0.8.6 for inspection. 
Results logged to /var/lib/gems/1.9.1/gems/curb-0.8.6/ext/gem_make.out 

我没有任何想法如何解决这个问题。我在谷歌寻找一些解决方案，但没有找到任何有助于我解决这个问题的方法。请帮忙...

编辑：

这里是mkmf.log文件。也许这将是有益的调试运行：

Answer 1

如果你是在Ubuntu上，然后再继续这样做：

：从这里

sudo apt-get install libcurl3 libcurl3-gnutls libcurl4-openssl-dev 

或者其他操作系统上安装，下载包中选择您的操作系统后，

http://curl.haxx.se/dlwiz/?type=devel

Answer 2

您的Mint安装可能缺少卷曲开发库。从以前的答案

sudo apt-get install libcurl3 libcurl3-gnutls libcurl4-openssl-dev

sudo apt-get install libcurl4-openssl-dev 

Answer 3

使用命令有时薄荷不能因为一个错误的安装libcurl4-openssl-dev：

试试这个在命令行上。

The following packages have unmet dependencies: 
libldap2-dev : Depends: libldap-2.4-2 (= 2.4.31-1+nmu2ubuntu8.2) but 2.4.31-1+nmu2ubuntu8.3 is to be installed 
E: Unable to correct problems, you have held broken packages. 

在我来说，我已经与下一个命令解决它：

sudo aptitude install libldap2-dev

起初，它建议什么都不做，我已经没有选择的话，就建议我降级当前安装到适当的版本。我选择了“是”。然后像往常一样安装libcurl4-openssl-dev
