安装/捆绑gem unf_ext -v’0.0.6’时出错
我正在尝试捆绑unf_ext -v '0.0.6'但我一直收到此错误：
Gem::Ext::BuildError: ERROR: Failed to build gem native extension. checking for main() in -lstdc++... yes checking for ruby/encoding.h... yes creating Makefile make "DESTDIR=" clean make "DESTDIR=" compiling unf.cc In file included from unf.cc:1: In file included from ./unf/normalizer.hh:4: In file included from /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/vector:265: In file included from /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/__bit_reference:15: In file included from /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/algorithm:628: In file included from /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/memory:604: /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/iterator:341:10: fatal error: '__debug' file not found #include ^ 1 error generated. make: *** [unf.o] Error 1 make failed, exit code 2
我已经运行了gem update --system并且我已经brew install coreutils但我仍然遇到了同样的错误。
更新：答案
从Apple Developer下载并安装了commandlinetoolsosx10.10forxcode6.2.dmg 。 无需卸载任何东西。
这是新的xcode工具中的一个错误。 在我的案例中，它打破了eventmachine。 有关使用虚拟文件和重新安装链接的答案更新OSX命令行工具6.3后，请参阅缺少C ++标头<__ debug> 。 我降级到6.2，问题消失了。
这样做对我有用：
echo '#define _LIBCPP_ASSERT(x, m) ((void)0)' | sudo tee -a /Library/Developer/CommandLineTools/usr/include/c++/v1/__debug > /dev/null
然后再次运行bundle 。
而且，由于这仅仅是Apple发布补丁之前的临时修复，因此请删除新创建的文件：
sudo rm /Library/Developer/CommandLineTools/usr/include/c++/v1/__debug
