Question

在Ubuntu 12.04下捕获此错误：

Building native extensions. This could take a while...
ERROR: Error installing json:
ERROR: Failed to build gem native extension.

/home/allaud/.rvm/rubies/ruby-1.9.3-p392/bin/ruby extconf.rb
creating Makefile

make
compiling generator.c
linking shared-object json/ext/generator.so
gcc: error: generator.o: No such file or directory
make: *** [generator.so] Ошибка 1

Gem files will remain installed in /home/allaud/.rvm/gems/ruby-1.9.3-p392/gems/json-1.7.7 for inspection.
Results logged to /home/allaud/.rvm/gems/ruby-1.9.3-p392/gems/json-1.7.7/ext/json/ext/generator/gem_make.out

我正在使用新的rvm和ruby 1.9.3并且只与json gem有同样的麻烦。

尝试执行时发生错误：

gem install json

如果我添加sudo一切正常，但我不能（也不应该）使用suv和rvm命令。

Answer 1

sudo apt-get install ruby1.9.1-dev

可能会解决。欢呼！

Answer 2

尝试运行以下命令（适用于ubuntu 14.04）：

$ sudo apt-get install libgmp3-dev

然后安装json

$ gem install json

Answer 3

对我来说这很有用（来自@ mjgpy3的解决方案）

sudo apt-get install ruby-json

尝试在Ubuntu 12.04下安装json时出错
