Windows：CouchDB在重裝過程中崩潰

Question

我前段時間在Windows機器上安裝了CouchDB，工作正常，版本爲1.1.0。現在（第一次安裝幾個月後），我嘗試卸載現有的CouchDB 1.1.0，併成功地將安裝目錄中的文件夾'/ etc'和'/ var'保留下來。 現在我正嘗試在不刪除上述文件夾的情況下使用setup-couchdb-1.2.0_otp_R15B.exe重新安裝。重新安裝後，當我試圖連接到數據庫時，我在日誌中得到下面的錯誤。請幫助什麼可能是問題...

看起來你會遇到COUCHDB-1482問題。嘗試安裝更多的recent CouchDB release（或1.2.2，如果您想停留在1.2.x分支上），修復了問題。

另外，儘量明確CouchDB的安裝：某處移動你的etc和var迪爾斯，CouchDB的卸載和刪除保持文件，安裝的CouchDB並移動var回數據。不要在舊版本中移動舊的etc，而必須手動將local.ini文件的配置更改備份（不要覆蓋default.ini文件！）以確保不會有任何配置衝突。
