Upload of image failed: decoder jpeg not avail...

使用django.modules 中image.save() 方法出現Upload of image failed:  decoder jpeg not available錯誤，出現這個的緣由時在linux 的 PIL中jpeg support 尚未裝好

解決：

首先 卸載 PIL 若是有安裝

pip uninstall PIL

 

而後 安裝libjpeg

sudo yum install -y libjpeg-devel

 

最後 安裝 PIL

pip install PIL

 成功後會看到
