Thumbor：IO錯誤：解碼JPEG不適

我工作VTNC，試圖運行Thumbor的入門第一個樣本，但它返回我這個錯誤：Thumbor：IO錯誤：解碼JPEG不適

我在Mac上，我已經通過pip安裝了它，繼Documentation之後。它說PIL默認安裝...

我該如何解決這個問題？

這是我pip freeze輸出：

(thumbor)mac:thumbor pzanetti631$ pip freeze 
Pillow==2.1.0 
derpconf==0.4.9 
pycrypto==2.6.1 
pycurl==7.19.3 
python-magic==0.4.6 
six==1.5.2 
thumbor==3.15.0 
tornado==3.1.1 
wsgiref==0.1.2

乾杯，

聽起來像是'PIL'未經JPEG支持安裝。你不能重新安裝PIL或在你的程序周圍創建'virtualenv'嗎？ – Krumelur

@Krumelur我已經在virtualenv下，無法刪除/安裝PIL ... – sonnuforevis

下面是我（奇怪）解決的問題：

1）後安裝Thumbor，刪除枕頭（截至今天，它安裝版本2.1.0）;

2）（重新）安裝枕頭（截止到今天，它會安裝版本2.3.0）;和

3）之後，（重新）安裝Thumbor。

這真的很奇怪。我是thumbor的提交者之一。它應該與枕頭2.1.0一起工作。你有沒有安裝PIL？安裝PIL枕頭將不起作用。

對不起，您有任何問題。請您在下次卡住時在項目中創建問題！

乾杯，貝爾納Heynemann
