Thor Argument嘗試創建新的Rails應用程序時出錯

Question

我正在嘗試使用rails-api創建一個新的應用程序。 當我運行rails-api new mynewapp我得到以下內容：

/Users/sandy/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/thor-0.19.1.1/lib/thor/parser/option.rb:125:in `validate_default_type!': An option's default must match its type. (ArgumentError)

嘗試使用rails new mynewapp ，我得到完全相同的錯誤，除了代替

...gems/rails-api-0.4.0/bin/rails-api:3:in `<top (required)>'

我明白了

...gems/railties-4.2.4/bin/rails:9:in `<top (required)>'

甚至運行rails -v也會出現同樣的錯誤。

谷歌沒有幫助。 有誰知道可能導致這種情況的原因是什么？

Answer 1

如果你運行rails -v並得到一個錯誤，你的安裝可能很糟糕。 我試着重新安裝rails ...

請關注此： http ： //installrails.com/

Answer 2

看起來像托爾0.19.1.1做了一個突破性的改變。 嘗試將其更改為0.19.1並查看是否可以解決問題。
