Ruby版本：2.3.0和Rails版本：4.0.3

我按照建议here尝试了解决方案，但这也没有用。如果有人知道这个问题或者过去已经解决了这个问题，请帮助我。

Answer 1

如果链接中的上述解决方案没有为您锻炼，请尝试安装这两个

"<spring:url value="/product/${product.id}" />"

让我知道这是否有效

Answer 2

尝试完所有后，我的解决方案就是下一个命令：

rvm get head
rvm –force install 2.3.0 # put your version of ruby
rvm use 2.3.0 # the same version as above
gem install bundle
gem install rails

Json Gem上的Rails Bundle安装失败：失败
