最近在用Python開發自己的博客,需要用到Python生成驗證碼,當然肯定要用到Python的圖形處理庫PIL,因爲我用的是windows。
所以在安裝好pil之後就開始寫,就按照題目所說出現了The _imagingft C module is not installed 錯誤,找了很多建議,最後確定在windows下應該用pillpw。下載地址點擊打開鏈接找到Pillow‑2.5.2.win32‑py2.7.exe因爲我用的是python2.7和win32系統,所以就應該下載這個,大家可以根據自己的需求找到響應的包進行安裝,Pillow, 它是對PIL的一些BUG修正後的編譯版
到了這裏又遇見一個錯誤,那就是在使用Image.save('code.jpg','jpg')的時候會出現KeyError:’jpg‘錯誤,
看stackoverflow文章http://stackoverflow.com/questions/21128256/why-does-pillow-not-recognize-the-jpeg-format
受到啓發之後只需要把import Image改爲from PIL import Image 就行了
順便附上一個生產中文驗證碼的代碼
