pip install PIL -E TICKETS-1 - No JPEG/PNG support
我正在处理图片裁剪器，但是我无法进行表单验证.上传GIF图片时，该表单已通过验证，但是我尝试使用的其他任何格式都会引发以下异常:
I'm working on a picture cropper, and I'm having trouble with my form validation. The form is validated when uploading a GIF picture, but any other format I try raises the following exception:
Upload a valid image. The file you uploaded was either not an image or a corrupted image.
表格
<form enctype="multipart/form-data" method="post" action="/pic/">{% csrf_token %}
{{ form.as_p }}
<p><input type="submit" value="View uploaded image"></p>
<input type="hidden" name="stage" value="crop">
</form>
查看
if request.method == 'POST':
form = ProfilePicForm(request.POST, request.FILES)
if form.is_valid():
*do stuff*
else:
logger.debug('Form errors == [%s]' % form.errors)
在安装PIL(使用easy_install)之前，我已经安装了libjpeg-dev(使用apt-get).起初，我认为这可能是由于libjpeg-dev或PIL的安装不正确造成的，但是对于其他格式(如png)，问题是否还会继续存在?实际上，png图像也确实会出现此问题.我没有遇到jpeg解码器问题，所以我认为不是这样，但是我不确定.另外，我正在使用django开发服务器.
I have installed libjpeg-dev(using apt-get) before installing PIL(using easy_install). At first, I thought this might be due to an incorrect installation of either libjpeg-dev or PIL, but would the problem persists for other formats like png? This problem does in fact occur for png images as well. I'm not getting a jpeg decoder problem, so I'm thinking it's not that, but I'm not sure. Also, I'm using the django development server.
我决定尝试重新安装PIL.我删除了我的PIL安装文件夹
/usr/local/lib/python2.7/dist-packages/PIL
和我的PIL.pth文件(在同一dist-packages文件夹中).我使用sudo python setup.py install运行setup.py脚本.然后，我运行了selftest.py脚本，它在第一次测试中失败了:
I decided to try a reinstall of PIL. I deleted my PIL install folder
/usr/local/lib/python2.7/dist-packages/PIL
and my PIL.pth file (in the same dist-packages folder). I ran the setup.py script using sudo python setup.py install. I then ran the selftest.py script, and it fails on the first test:
--------------------------------------------------------------------
PIL 1.1.7 TEST SUMMARY

Python modules loaded from ./PIL

Running selftest:

Got: decoder jpeg not available
1 items had failures:
1 of 57 in selftest.testimage
***Test Failed*** 1 failures.
*** 1 tests of 57 failed.
我不确定如何使PIL与上面列出的不受支持的模块一起使用.我可以验证是否具有zlib1g-dev，libfreetype6-dev，liblcms1-dev和libjpeg62-dev，以及库本身已安装在系统上，因为当我尝试使用apt-get安装它们时，它说我已经拥有最新版本
I'm not sure how to get PIL to work with the unsupported modules listed above. I can verify that I have zlib1g-dev, libfreetype6-dev, liblcms1-dev and libjpeg62-dev, and the libraries themselves installed on my system because when I try to install them with apt-get, it says I already have the latest version.
推荐答案
尝试从源代码下载PIL，然后编辑setup.py，并添加以下行:
Try downloading PIL from source, then edit setup.py adding this line:
add_directory(library_dirs, "/usr/lib/i386-linux-gnu")
在此行之前(214):
before this line (214):
add_directory(library_dirs, "/usr/lib")
然后
sudo python setup.py install
现在应该可以正常工作
