我想在我的计算机上安装 Less 编译器，但是当我运行以下命令时：
sudo gem install less
并且 make 命令停止了以下错误：
g++ -shared -o v8.so v8_locker.o v8_debug.o v8_date.o v8_object.o v8.o rr.o v8_context.o v8_value.o v8_script.o v8_v8.o v8_callbacks.o v8_handle.o v8_weakref.o v8_template.o v8_message.o v8_function.o v8_string.o v8_array.o v8_try_catch.o v8_external.o v8_exception.o -L/home/segi/.gem/ruby/1.9.1/gems/libv8-3.3.10.2/lib/libv8/build/v8 -L. -L/usr/lib -L. -Wl,-Bsymbolic-functions -rdynamic -Wl,-export-dynamic -lruby-1.9.1 -lpthread -lpthread -lrt -ldl -lcrypt -lm -lc -lv8

make: *** [v8.so] Error 1
缺少哪个包？或者是什么问题？谢谢您的回答！
sudo apt-get install libv8-dev
这是一个好的包，但现在我收到以下错误：

答案1
听起来好像缺少 v8 开发标头。尝试安装 libv8-dev 包，
sudo apt-get install libv8-dev。
