「格式不正確的版本號字符串的mingw32」 開始軌道

Question

我的操作系統時：Windows XP中，紅寶石：1.8.7，導軌：2.3.5

一切都很好，但我只安裝了一個「GCC-4.4.0- mingw32-bin「，然後運行gem install rdiscount，那麼我的導軌無法啓動。

現在，當我運行ruby script/server，或rake gems:install，會出現以下錯誤：

rake aborted! 
Malformed version number string mingw32 

(See full trace by running task with --trace)

現在我必須重新安裝我的Ruby和Rails，但同樣的錯誤仍然出現。而我在谷歌搜索，發現沒有解決方案。看來我必須重新安裝我的Windows XP。有人知道原因？幫助...

Answer 1

剛纔，我找到了解決辦法：刪除「供應商/寶石」

下的文件的原因可能是我跑rake gems:unpack我安裝gcc後，因此一些無效的文件被解壓到「寶石「目錄。刪除它們後，一切正常。

Answer 2

問題是，您已經解壓了一個具有Windows專用擴展版本的gem。這樣的寶石有一個後綴，包括mingw32（例如nokogiri-1.4.3.1-x86-mingw32）。執行rake gems:unpack後，您應該刪除這些解壓縮的文件夾。

手頭上，這避免了格式錯誤的版本字符串（您報告的問題）的問題。另一方面，用戶和具有不同操作系統的服務器（linux/mac osx）能夠自行構建gem的本地擴展（不適用於windows版本）。
