爲什麼RVM寶石列表顯示我沒有安裝的寶石？

Question

我在Dreamhost共享主機。我安裝了RVM來運行Ruby 1.9.2，並創建了一個空的gemset來處理。我運行了gemset empty命令，以確保它真的是空的。

奇怪的是，如果我運行rvm gemset use MYGEMSET，然後運行rvm do gem list，我會得到Dreamhost提供的一長串寶石。

[phantom]$ rvm do gem list 
WARN: `rvm do gem list` is deprecated, use `rvm all do gem list` or `rvm 1.9.2 do gem list` instead.

我有兩個問題：

1. 如何創建一個真正的筒倉我的項目，一個寶石這是真正爲空？
2. 如何擺脫當地寶石中的「無效gemspec」錯誤？因爲如果我切換回rvm use 1.8.7，然後運行gem list我不要得到「無效的gemspec」錯誤！

打字rvm use ruby-1.9.2@MYGEMSET，然後運行which gem點~/.rvm/rubies/ruby-1.9.2-p290/bin/gem我認爲這是正確的。

Answer 1

最有可能出現這種情況是因爲全球寶石包含all寶石，嘗試：

rvm 1.9.2@global gem list 

你可以用寶石列表比較這對只看到你的寶石：

rvm use 1.9.2 
diff --normal <(gem list) <(rvm 1.9.2@global gem list) | sed '/^[^<]/ d ; s/^< //' 

或僅使用GEM_HOME作爲GEM_PATH：

GEM_PATH=$GEM_HOME gem list 

Answer 2

我相信rvm do gem list會列出所有紅寶石（以及所有寶石）的寶石。如果你有rvm設置並且源代碼正確，你應該可以使用所有的shell腳本（ruby，gem，bundle等），而不用rvm作爲前綴。

使用正確的ruby版本+ gemset（即：rvm use ruby-1.9.2@MY_GEMSET）後，嘗試gem list。如果這樣會產生奇怪的結果，請查看which gem使用哪個寶石。

Answer 3

RVM做寶石列表已經過時

rvm gemset list: List your gemsets 

rvm gemset create your_gemset: Create a gemset 

rvm gemset use your_gemset: Use a gemset 

gem list: List current gemset gems 

使用RVM信息檢查是否使用了正確的紅寶石和寶石。最好的做法是創建一個.rvmrc文件
