在雪豹上安装一些宝石时出错-libxml2

macports osx-snow-leopard development-environment rubygems macos

tfwright · 技术社区 · 15 年前

升级到雪豹之后,我发现安装一些宝石不再有效,包括Webrat、Mechanical等。每次出现此错误时:

checking for xmlParseDoc() in -lxml2... no
libxml2 is missing.  try 'port install libxml2' or 'yum install libxml2'
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

不,我没有尝试将它与MacPorts一起安装,因为几年前我发现自己无法轻松降级/管理端口时,我放弃了MacPorts。从那时起,我就从源头上用手变得非常舒适了,这是我第一次碰到我所不熟悉的东西。我愿意被说服回到MacPorts,但只有在没有简单的解决办法的情况下,我才会错过。

似乎libxml2并没有真正丢失,也许只是过时了?…

Floyd的解决方案是过度杀戮——我也遇到了同样的问题,开始使用与xml2相关的/opt/local文件,但是他的“find”命令并没有在opt/local/lib中显示实际的lib xml2文件。可能你只是需要用核武器。

以下是我的核文件:

/opt/local/include/libxml2
/opt/local/var/db/dports/distfiles/libxml2
/opt/local/var/db/dports/receipts/libxml2
/opt/local/var/db/dports/software/libxml2
/opt/local/var/db/dports/rsync.rsync.darwinports.org_dpupdate_dports/textproc/libxml2
/opt/local/share/gtk-doc/html/libxml2
/opt/local/var/db/dports/sources/rsync.rsync.darwinports.org_dpupdate_dports/textproc/libxml2

但在你尝试之前-只需核库文件 sudo rm/opt/local/lib/libxml2.*

当我尝试安装之后,它开始编译它,但后来又出现了libz问题…

所以在/opt/local/lib中使用核武器 sudo rm-rf/opt/local/lib/libz.*

它编译得很好!

因此,尝试nuking/opt/local/lib libxml2.*和libz.*文件,查看它是否编译,如果不编译,nuke/opt/local/includes

更新

如另一个答案所述,下面的解决方案是“过度杀戮”,因为它从您的系统中删除了MacPorts,我认为我之前已经做过。小心操作。可能有一种方法可以使用MacPorts来更新libxml2安装。

我(至少在我的机器上)解决了这个问题。

当我意识到跟踪中没有任何东西表明缺少libxml2,而是检测到的版本有问题时,我环顾四周以确认这一事实。当然了, nokogiri website (许多类似的bug报告指出我)毫不确定地指出,雪豹船上有一个良好的工作版本libxml2。

因此,我推断很久以前我一定是通过另一种方式安装了一个版本。我会记得如果我是手工安装的,那么只剩下一个选项,frickin'macports。

$ libxml2-2.7.1 tfwright$ sudo find / -type d -name "libxml2" 
find: /dev/fd/3: Not a directory
find: /dev/fd/4: Not a directory
/Developer/SDKs/MacOSX10.4u.sdk/usr/include/libxml2
/Developer/SDKs/MacOSX10.5.sdk/usr/include/libxml2
/Developer/SDKs/MacOSX10.6.sdk/usr/include/libxml2
/opt/local/include/libxml2
/opt/local/share/gtk-doc/html/libxml2
/opt/local/var/macports/distfiles/libxml2
/opt/local/var/macports/receipts/libxml2
/opt/local/var/macports/software/libxml2
/opt/local/var/macports/software/libxml2/2.6.30_0/opt/local/include/libxml2
/opt/local/var/macports/software/libxml2/2.6.30_0/opt/local/share/gtk-doc/html/libxml2
/opt/local/var/macports/sources/rsync.macports.org/release/ports/textproc/libxml2
/usr/include/libxml2
/usr/share/gtk-doc/html/libxml2

一个……的儿子,就这么飞走了。 /opt/local/var/macports 我首先尝试过的,似乎没有解决问题,所以我去了 big guns .

sudo rm -rf \
/opt/local \
/Applications/DarwinPorts \
/Applications/MacPorts \
/Library/LaunchDaemons/org.macports.* \
/Library/Receipts/DarwinPorts*.pkg \
/Library/Receipts/MacPorts*.pkg \
/Library/StartupItems/DarwinPortsStartup \
/Library/Tcl/darwinports1.0 \
/Library/Tcl/macports1.0 \
~/.macports

之后,一切都安装好了。这是正确的。不要相信错误消息的建议!我不需要用MacPorts重新安装libxml2,我需要 清除系统中所有MacPorts的痕迹 从垃圾堆外面一直萦绕着我。

您要安装的gems需要libxml2。如果您愿意从源代码安装,请安装 libxml2 .

您可能会遇到依赖性问题,其中libxml2依赖于一系列其他需要手动构建和安装的包。这就是为什么MacPorts最终变得有用的原因之一。
