我创建了一个python-flask
托管在heroku上的应用程序。我很有趣PIL
python 中的图像库。我无法安装PIL
在heroku实例中。
我尝试过以下几种方法。
方法一:
Added PIL=1.1.7
in requirements.txt
这里我有例外
Some externally hosted files were ignored (use --allow-external PIL to allow).
方法2:
heroku run pip install PIL --allow-unverified=PIL --app=nava-app
这有助于安装PIL
我收到了安装成功的消息。Successfully installed PIL
Cleaning up...
但是,在我推送最新的代码后,我得到了import error
for PIL
。我已通过命令附加了下面的日志文件heroku logs --app=nava-app
.

方法三:
即使我尝试导入 PIL python 模块作为我的应用程序的一部分,例如第三方模块,它表明imaging C library not installed
你能帮我在heroku实例中安装PIL吗?
