安裝pywin32時，出現找不到python27註冊資訊的解決辦法

標籤：rip   written   util   令行   and   2-2   script   esc   val   

1. 檢查一下註冊表是否存在python其它版本的資訊

方法：

1）在命令列中輸入regedit開啟註冊表

2）在HKEY_CURRENT_USER\Software中找一下是否存在python註冊資訊，如果存在，檢查一下是否是python27版本，且是否包含下面兩個節點

再檢查一下其對於的安裝路徑是否正確。如果不知道如何檢查，可以把python節點資訊右擊選擇刪除。如果python註冊資訊不存在，這裡就不用操作了。

 

2.執行下面連結中的python指令碼（python27使用正常，無需修改任何內容）

 

3.執行後再檢查一下註冊表。如下

4. 再次安裝pywin32-220.win32-py2.7.exe，結果安裝成功

 

 

另一外一種方法：就是執行下面的python指令碼
