Predix：没有名为_tkinter的模块

Question

我试图在Predix上推送一个Python Microservice。
该代码具有matplotlib依赖关系。

cf push对于具有以下堆栈跟踪的应用程序失败。

我正在使用python_buildpack。

在此先感谢，为解决此问题的任何帮助。

Answer 1

python构建包支持使用Conda包管理器而不是pip。你可能想试试这个。

http://docs.cloudfoundry.org/buildpacks/python/#miniconda

利用这一点，我是能够部署它使用Matplotlib来CF.这个示例应用程序

希望帮助！

Answer 2

假如你运行的是Linux做 sudo易于得到安装python-tk的

也许你有事后重新编译了Python。
