帶附加包含和lib路徑的gem install

Question

我試圖在Mac OS X 10.9.2上構建和安裝nokogiri Rubygem，它需要libxml2。薪火--with-xml2-lib和--with-xml2-include選項似乎沒有生效

$ gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2 --with-xml2-lib=/usr/local/lib 

設置LDFLAGS和CPPFLAGS確實是（使用的libxml2代替的Xcode的自制版）

$ LDFLAGS="-L/usr/local/opt/libxslt/lib -L/usr/local/opt/libxml2/lib" CPPFLAGS="-I/usr/local/opt/libxslt/include -I/usr/local/opt/libxml2/include" gem install -r nokogiri 

錯誤輸出始終是不行的同樣

checking for libxml/parser.h... yes 
checking for libxslt/xslt.h... yes 
checking for libexslt/exslt.h... yes 
checking for iconv_open() in iconv.h... yes 
checking for xmlParseDoc() in -lxml2... no

libxml2 is missing. please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

你讀過：https://github.com/sparklemotion/nokogiri/wiki/What-to-do-if-libxml2-is-being-a-jerk

這通常有幫助。其他類似的問題發現這很有幫助。

Answer 2

使用自制安裝寶石取決於實際安裝寶石做的伎倆在我面前，然後再設置NOKOGIRI_USE_SYSTEM_LIBRARIES=1庫。

彙總：

• 如果以前安裝，卸載寶石：
  $ gem uninstall nokogiri

• 使用自制安裝libxml2，libxslt和libiconv：
  $ brew install libxml2 libxslt libiconv

• 安裝寶石指定pa部份的圖書館對鏈接：
  $ NOKOGIRI_USE_SYSTEM_LIBRARIES=1 gem install nokogiri -- --use-system-libraries --with-iconv-dir="$(brew --prefix libiconv)" --with-xml2-config="$(brew --prefix libxml2)/bin/xml2-config" --with-xslt-config="$(brew --prefix libxslt)/bin/xslt-config"

Answer 3

我有同樣的問題，但對我來說了以下工作：

gem install -- --with-opt-include=/usr/local/opt/libxml2/include/libxml2
