As often happens, it returns an error stating that it doesn't have all the tools on the machine necessary to build the extension:Building native extensions.

It appears that I'm missing this ntohl() function, can anyone tell me in which Debian package I can find this function?推荐答案您必须设置正确的编译器标志： https://github.com/sparklemotion/nokogiri/issues/680#issuecomment-5830358You have to setup proper compiler flag: https://github.com/sparklemotion/nokogiri/issues/680#issuecomment-5830358 gem install xmlparser - --with-cflags = - Wformat-securityroot@c6d50bebf05f:/var/lib/gems/2.0.0/gems# gem install xmlparser -- --with-cflags="-Wformat-security"Building native extensions with: '--with-cflags=-Wformat-security'This could take a while...Successfully installed xmlparser-0.7.2.1Parsing documentation for xmlparser-0.7.2.1unable to convert "\xA0" from ASCII-8BIT to UTF-8 for /var/lib/gems/2.0.0/extensions/x86_64-linux/2.0.0/xmlparser-0.7.2.1/xmlparser.so, skippingunable to convert "\xCD" from ASCII-8BIT to UTF-8 for README.ja, skippingunable to convert "\xC0" from ASCII-8BIT to UTF-8 for ext/xmlparser.o, skippingunable to convert "\xA0" from ASCII-8BIT to UTF-8 for ext/xmlparser.so, skippingunable to convert "\xA0" from ASCII-8BIT to UTF-8 for lib/xmlparser.so, skippingInstalling ri documentation for xmlparser-0.7.2.11 gem installed 这篇关于RubyGem本机扩展 - 在-lsocket中找不到ntohl（）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
