尝试将应用程序推送到IBM Cloud时为什么会收到错误消息?

标签: python ibm-cloud cloudfoundry

我想通过使用以下命令将简单的Flask应用程序推送到IBM云:

%%bash
cd /resources/labs/CV0101EN/CV0101EN-capstone-project/app
ibmcloud app push

很遗憾,我在此过程中收到错误消息。 通过查看错误,我认为由于某种原因,python安装存在问题,但是我不知道是什么原因造成的。有人知道这里的问题在哪里吗?我将不胜感激。

安装日志:

以下是Jupiter笔记本中显示的错误。

由于大小限制,buildpack不能包含曾经创建的所有Python版本。从输出中可以看到,buildpack会告诉您所请求的版本以及受支持的版本。

错误:无法安装python:在[2.7.16 2.7.17 3.5.7 3.5.9 3.6.9 3.6.10 3.7.5 3.7.6 3.8中找不到3.6.8的匹配项.0 3.8.1]

简短的回答是,您需要在 quantity value modified_value 0 1 12.5 6.2 # applied 1 time 1 3 9.0 1.1 # applied 3 times, 9.0 -> 4.5 -> 2.2 -> 1.1 中指定受支持版本列表中的版本。可以是runtime.txt3.6.9

一个更好的解决方案是不指定特定版本,而指定分支。如果您要设置3.6.10,那么当buildpack不再支持3.6.9时,您将在2个月内再次遇到此问题(buildpacks不断升级依赖关系,因此您可以获得最新的安全性和错误修复)。

使用3.6.x,您将只获得buildpack支持的3.6分支的最新版本。在上面的示例中,这将导致安装3.6.10。在两个月内出现3.6.11时,您将自动获得3.6.11。

更改项目目录中的runtime.txt文件中的Python版本即可解决此问题。 Python已成功安装。
