Question

我发誓，我已经看到了在stackoverflow上安装Ruby的所有讨论......没有帮助。我安装了Xcode 4.1以及rvm 1.16.19。

已安装libksba。

某些版本的Ruby以某种方式安装但我不知道哪个版本 - 因为如果我执行任何类型的Ruby命令 - “ruby”本身，“ruby --version”，无论如何，我得不到回应，并得到一个提示我必须ctrl / c。

是否使用RVM，每当我尝试安装任何版本的Ruby时，我都会得到这个输出：

Error running 'env LDFLAGS=-L/opt/sm/pkg/active/lib CFLAGS=-I/opt/sm/pkg/active/include CPATH=/opt/sm/pkg/active/include -L/Users/Dauber/.rvm/usr/lib ./configure --enable-shared --disable-install-doc --prefix=/Users/Dauber/.rvm/rubies/ruby-1.9.3-p286', please read /Users/Dauber/.rvm/log/ruby-1.9.3-p286/configure.log
There has been an error while running configure. Halting the installation.
ruby-1.9.3-p286 is not installed.

以下是上述configure.log的输出：

[2012-11-08 20:46:41] env LDFLAGS=-L/opt/sm/pkg/active/lib CFLAGS=-I/opt/sm/pkg/active/include CPATH=/opt/sm/pkg/active/include -L/Users/Dauber/.rvm/usr/lib ./configure --enable-shared --disable-install-doc --prefix=/Users/Dauber/.rvm/rubies/ruby-1.9.3-p286 --with-gcc=clang

checking target system type... x86_64-apple-darwin11.4.2
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.

现在，一个奇怪的事情是系统中没有任何名为“config.log”的文件，所以我不能“看到”它“以获取更多细节。”

另一个奇怪的事情......我已经使用gcc和gcc-4.2在这台机器上编译了几十个C程序 - 我只是尝试了AGAIN并且它们工作正常，所以我不知道究竟是什么交易...

我尝试从https://github.com/kennethreitz/osx-gcc-installer安装无效;它完全没有区别。

这一切都在我的MacBook上，运行OSX 10.7.5。奇怪的是......我的iMac运行完全相同版本的Lion时出现了ZERO问题......事实上，我甚至不需要安装Ruby - 它碰巧已经有1.9.2了;我只需要添加Rails并且所有工作都很完美......到底有什么不同以至于我无法在MacBook上运行这些东西???

PRUSSWAN之后的链接：长话短说，prusswan链接的另一篇文章提到Rails安装程序中存在一个错误，需要更改/ etc / rvmrc。我做了更改但得到了与我之前尝试安装ruby时完全相同的错误消息。这就是configure.log现在所说的：

所以看起来生成的./configure文件会生成拼写错误或其他内容......

Answer 1

关注this guide，其中介绍了如何使用RVM设置Ruby。

Answer 2

哇......我无法相信，但我找到了自己问题的答案，而且非常糟糕。

我应该使用“rvm remove”命令 - 尝试过，突然就像魔术一样，我现在可以安装任何和所有版本的Ruby了。

现在看看Aptana是否会让我创建一个新的Rails项目。：）

感谢您的反馈，所有......
