问题描述
我最近将Mac上的操作系统更新为El Capitan，此后一直遇到尝试运行WeasyPrint的问题.我已经更新了macports，已卸载并重新安装了所有macport依赖项.我还通过pip卸载并重新安装了WeasyPrint，没有问题，但仍然无法运行.我的〜/.profile中也有导出DYLD_FALLBACK_LIBRARY_PATH ="/opt/local/lib"，这有助于解决导入错误，并允许在安装El Capitan之前运行WeasyPrint.当我在终端上输入weasyprint --help时，出现以下输出/错误:
I recently updated my OS on my mac to El Capitan and since then have been running into issues trying to run WeasyPrint. I have updated macports, uninstalled and reinstalled all of the macport dependencies. I've also uninstalled and reinstalled WeasyPrint via pip with no issues, but still it doesn't run. I also have the export DYLD_FALLBACK_LIBRARY_PATH="/opt/local/lib" in my ~/.profile which helped solve the import errors and allowed WeasyPrint to run before I had El Capitan installed.When i type weasyprint --help into the terminal i get the following output/error:

raise OSError("dlopen() failed to load a library: %s" % ' / '.join(names))

这看起来像是路径问题，但我已经尝试了所有我能想到的东西.有什么建议吗?
It looks like a path problem, but I've tried everything i can think of. Any suggestions?
推荐答案
好，所以我找到了解决方案(无需更改任何原始的weasyprint或cairocffi文件).显然，OS X 10.11引入了SIP，该SIP禁用了DYLD路径变量的使用.为了解决这个问题，我禁用了SIP.这样做的说明是此处.基本上在启动时按住Command + R键.单击顶部的实用程序，然后进入终端.键入csrutil disable，然后重新启动，这应该可以解决.
Ok so I found a solution (without changing any of the original weasyprint or cairocffi files). Apparently OS X 10.11 introduces SIP which disables the use of DYLD path variables. To get around this I disabled SIP. The instructions to do so are here. Basically hold command + r when booting up. Click utilities at the top and go into the terminal. type in csrutil disable then reboot and that should fix it.
