我正在学习Rails上的ruby,并将我的项目托管在c9.io上。在迁移到Amazon AWS Cloud9的过程中,我必须将我的gem重新安装到我的项目中。我在尝试构建gem本机扩展时遇到配置错误。
在将“ gem install fog”输入命令行之前,我实际上不确定如何配置此gem。我曾尝试在Fog网站上搜索,但无法在其页面上找到信息。
错误是:
Building native extensions. This could take a while...
ERROR: Error installing fog:
ERROR: Failed to build gem native extension.
current directory: /home/ubuntu/.rvm/gems/ruby-2.3.4/gems/ovirt-engine-sdk-4.3.0/ext/ovirtsdk4c

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.
Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/home/ubuntu/.rvm/rubies/ruby-2.3.4/bin/$(RUBY_BASE_NAME)
--with-libxml2-config
--without-libxml2-config
--with-pkg-config
--without-pkg-config
extconf.rb:29:in `<main>': The "libxml2" package isn't available. (RuntimeError)
To see why this extension failed to compile, please check the mkmf.log which can be found here:
/home/ubuntu/.rvm/gems/ruby-2.3.4/extensions/x86_64-linux/2.3.0/ovirt-engine-sdk-4.3.0/mkmf.log
extconf failed, exit code 1
mkmf.log说:
find_executable: checking for xml2-config... -------------------- no
--------------------
"pkg-config --exists libxml2"
package configuration for libxml2 is not found
我只是不知道如何将此日志消息转换为我的代码库,因此我可以安装fog并继续使用我的应用程序。

尝试安装xml2开发包:
apt-get install libxml2-dev
这应该有效! (之后,您可能需要重新安装Ruby。)

代替
gem 'fog'
使用
gem 'fog-aws'
在您的gem文件中,它应该可以工作。
