花了一些时间弄清楚这个:
gem install json
导致了这个错误:
Building native extensions. This could take a while...
ERROR: Error installing json:
ERROR: Failed to build gem native extension.

/usr/bin/ld: cannot find -lgmp
collect2: error: ld returned 1 exit status
make: *** [generator.so] Error 1
make failed, exit code 2
这里重要的一行是“找不到-lgmp”。
最佳答案
解决方案:
sudo apt-get install libgmp-dev
