Question

就像标题所说，我一直在尝试安装Heroku。但是，只要我运行任何heroku命令，我就会得到这个：

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

我运行这些命令来安装Heroku：

 sudo apt-add-repository 'deb http://toolbelt.herokuapp.com/ubuntu ./'
wget -O- https://toolbelt.heroku.com/apt/release.key | apt-key add -
 sudo apt-get update
sudo apt-get install heroku-toolbelt

任何人都可以帮助我吗？谢谢！

Answer 1

尝试运行此脚本

wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh

使用此命令后，安装没问题。

Answer 2

我有同样的错误。我认为这是Heroku CLI 3.9.4版本的一个问题，他们刚刚发布了3.9.5。更新后一切正常。

更新

sudo apt-get update
sudo apt-get upgrade

试图在Ubuntu上安装Heroku会给json和ruby带来错误
