Question

我想在ruby中安装restclient。我收到这些消息：

Building native extensions.  This could take a while...
ERROR:  Error installing rest-client:
ERROR: Failed to build gem native extension.

current directory: /var/lib/gems/2.3.0/gems/unf_ext-0.0.7.4/ext/unf_ext
/usr/bin/ruby2.3 -r ./siteconf20170427-2260-1nc7gtz.rb extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include /ruby.h

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.3.0/gems/unf_ext-0.0.7.4 for inspection.
Results logged to /var/lib/gems/2.3.0/extensions/x86_64-linux/2.3.0/unf_ext-0.0.7.4/gem_make.out

我的终端命令是：sudo gem install rest-client

有人能帮助我吗？

Answer 1

如果你的堆栈跟踪中有这个：

Makefile:207: recipe for target 'unf.o' failed

你缺少构建必需的g ++。在Ubuntu上，您可以使用以下命令安装：

sudo apt-get install build-essential g++

然后重新运行：

sudo gem install rest-client

Answer 2

系统上缺少开发头文件，运行：

sudo apt-get install ruby-dev zlib1g-dev liblzma-dev

Answer 3

首先需要确保拥有用于编译Ruby扩展模块的头文件。如果您使用的是Ubuntu（Ubuntu 16.04.3 LTS），请检查如下：

apt list --installed | grep ruby-all-dev

如果未找到任何内容，请安装它：

sudo apt-get install ruby-all-dev

现在您可以继续安装rest-client：

sudo gem install rest-client

无法安装restclient gem
