rvm安裝失敗，錯誤：「__rvm_detect_max_threads：cd：21：string not in pwd：/ ***」

Question

我剛將我的macOs升級到Sierra，並嘗試設置它。在試圖用RVM安裝Ruby，我得到這個非常奇怪的錯誤：

__rvm_detect_max_threads:cd:21: string not in pwd: /Users/sunday/workspace/contributions 

我在目錄中有/workspace/contributions，不知道是什麼錯誤只有一個文件夾，試圖刪除/workspace/contributions，但錯誤仍然存在。

在使用--debug選項，以下是跟蹤我：

，當我嘗試使用install，而不是reinstall也會發生這種情況。

在這裏可能會發生什麼，以及如何解決這個問題，以便在我的機器上安裝ruby？

Answer 1

根據這一線索https://github.com/rvm/rvm/issues/3686在Github上，我能得到它通過使用命令安裝：

rvm install ruby-2.3.1 --disable-binary -j 8 

根據註釋：

So it seems like the "detect number of CPU threads" functionality is, for whatever reason, breaking it on my machine.

Answer 2

➜ ~ ruby -v 
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16] 

刪除此默認在OSX中的達爾文版本的紅寶石。

卸載RVM

rvm implode 

安裝RVM按照文檔

\curl -sSL https://get.rvm.io | bash -s stable 

重新啓動終端，並確認RVM被正確安裝。
