[英]Unable to install Rails extconf.rb failed
I'm new to Ruby on Rails, and I'm getting the below error when I'm installing it. 我是Ruby on Rails的新手,我在安装时遇到了以下错误。
Please note, I have installed the latest Xcode and installed command line tools, and I'm using OSX 10.8.4. 请注意,我已经安装了最新的Xcode和已安装的命令行工具,我正在使用OSX 10.8.4。 I've installed Ruby 2.0.0 as well.
我也安装了Ruby 2.0.0。
-bash-3.2$ sudo gem install rails

我有类似的问题,它通过安装命令行工具得到解决:
xcode-select --install
The symlinking did not solve the problem for me. 符号化并没有为我解决问题。 I uninstalled my ruby that I previously had installed using rvm by typing
rvm uninstall ruby-2.0.0
and then I typed rvm requirements
. 我通过键入
rvm uninstall ruby-2.0.0
了我之前使用rvm uninstall ruby-2.0.0
,然后输入了rvm requirements
。 This command found that I needed a few other things, such as gcc46. 这个命令发现我需要一些其他的东西,比如gcc46。 It's strange that the gcc compiler was needed, even though I had installed the xcode command line tools, and gcc was most definitely installed on my system.
奇怪的是,即使我已经安装了xcode命令行工具,也需要gcc编译器,并且gcc绝对安装在我的系统上。
So, if none of the usual methods are working, give rvm requirements
a shot! 因此,如果通常的方法都不起作用,请给出
rvm requirements
!
I guess it's a same problem with this question . 我想这个问题也是同样的问题。
Try sudo ln -s /usr/bin/{llvm-,}gcc-4.2
and gem install rails
again. 再次尝试
sudo ln -s /usr/bin/{llvm-,}gcc-4.2
和gem install rails
。
By the way, you're in your own home directory, you don't have to use sudo
. 顺便说一下,你在自己的主目录中,你不必使用
sudo
。
I just ran into this with ruby 2.5.3
and was able to install cairo by calling: 我刚刚使用
ruby 2.5.3
遇到了这个问题并且可以通过调用来安装cairo:
PKG_CONFIG_PATH=/usr/local/opt/libffi/lib/pkgconfig gem install cairo -v '1.15.2'
Took a while to find something that worked, as I already had the command line tools installed, and am using asdf
not rvm
. 花了一段时间找到
rvm
东西,因为我已经安装了命令行工具,并且使用的是asdf
而不是rvm
。
