Question

我检查了系统更新，显示heroku和heroku toolbelt都已更新，但之后我收到此错误

heroku/vendor/gems/json-1.7.7/lib/json/common.rb:67:in `initialize': no implicit conversion of nil into Hash (TypeError)

无法运行任何heroku命令。以前它工作正常，但现在不行。

heroku，heroku-versions 3.9.4，之前是3.9.1

我有同样的错误。请注意，产生错误的json库不是来自您的宝石，而是带有一个heroku工具带分配。因此更新json是不够的，我认为这应该作为一个错误报告给heroku。

我现在的解决方法是安装一个新的json gem并从heroku toolbelt中删除其过时的版本1.7.7：

gem install json
sudo mv /usr/local/heroku/vendor/gems/json-1.7.7 /some/tmp
gem list json
  *** LOCAL GEMS ***
  json (1.8.1)
heroku version
  heroku-toolbelt/3.9.4 (x86_64-linux) ruby/2.1.1

更新：似乎此问题已在3.9.5中修复

当我犯下Heroku时，我得到了：

/app/vendor/lpxc/lpxc.rb:94: [BUG] hooks/pre-receive:99:in `exit': no implicit conversion from nil to integer (TypeError)
    from hooks/pre-receive:99:in `<main>'

我通过在本地运行bundle install来解决它，并将更新后的Gemfile.lock提交给Heroku。

heroku toolbelt`initialize'：没有将nil隐式转换为Hash（TypeError）
