問題： windows環境下python2.7使用dll = ctypes.cdll.LoadLibrary報錯WindowsError: [Error 126]

Connected to pydev debugger (build 183.5429.31)

這個問題的原因是由於路徑找的不對，正常情況下我們使用python代碼寫路徑時，\  斜槓應該改成 反斜槓 / ，

但是將反斜槓改正後，依舊是這樣的錯誤，（上面這個圖片是第二種方法成功的結果）

解決方法有兩種：

第一種：在本機配置環境的 path 目錄下加入 dll 的文件的目錄。

第二種：把dll 目錄放到 安裝python的目錄的地方python.exe 的目錄下。

這個時候就可以安心的使用了
