无法运行heroku-cli命令- npm的问题

Question

当我试图在Mac上运行heroku fork时，我突然遇到了使CLI无用的关键错误。这个问题以前并没有发生，我相信CLI可能已经自我更新，并开始造成问题。

~ ☽  heroku fork -a oldapp newapp

Help topics, type "heroku help TOPIC" for more details:

  heroku version                       # print the version
  heroku plugins                       # manage plugins
  heroku update                        # update heroku-cli

我已经尝试删除和重新安装heroku cli通过:自制，官方安装程序，甚至红宝石。由于错误似乎表明存在npm问题，所以我更新了npm和所有npm包，甚至能够显式地运行npm install -g heroku-cli-util@1.10.0，但这些都没有起到任何作用。

这里出了什么问题/我怎样才能解决这个问题？这对我来说是个关键问题。

我认为缓存被卡住了，尝试删除~/.heroku，然后再试一次。

编辑:原来这是Heroku私有npm服务器上缓存的一个问题。
