我试图安装nodejs并重新启动apache服务器这对解决这个问题没有帮助。
bundle show uglifier给出/usr/local/lib/ruby/gems/2.4.0/gems/uglifier-3.0.4
我想我已经正确安装了丑八怪。
同时
gem 'therubyracer', platforms: :ruby在Gemfile中未注释。请帮忙，我不知道怎么解决这个问题。
最佳答案
这是a known issue与therubyracer和红宝石2.4Ruby2.4的兼容性还有几个额外的问题，这些问题可以在https://github.com/cowboyd/therubyracer/issues/430的问题跟踪器中找到。
您应该使用早期版本的Ruby，例如2.3.3，直到新版本的rubyracer发布。
顺便说一句：有几个gems还不能与Ruby 2.4兼容为了避免在新版本发布后遇到大量兼容性问题，最好不要在发布的第一天进行升级
