django.test.client 上的 Django rest 框架导入错误

Posted 2023-02-24

【中文标题】django.test.client 上的 Django rest 框架导入错误

【英文标题】：Django rest framework import error in on django.test.client

【问题描述】：

我正在使用谷歌应用引擎开发服务器来运行在 mac os 上的 python。 我正在运行的项目是一个使用 djangae 和 django rest 框架的 appengine django 项目。

项目中的一切工作正常，但是一旦声明与 rest_framework 相关的导入，即使我目前没有运行任何测试，我也会收到关于 django.test.client 的错误。

我尝试执行的导入是“from rest_framework.decoraters import api_view”，只要我进行此导入或与其余框架相关的任何其他导入。

这是我在每次导入涉及其余框架时遇到的错误。

【问题讨论】：

你是如何包含这些库的？似乎您使用的 django 版本没有 DRF 所需的 django.test.client：github.com/tomchristie/django-rest-framework/blob/…

@chachan 我使用基本修复路径设置将 django 添加到项目 init 上的 python 路径中，我使用的 django 版本是 Django 1.8.2，并且确实包含 django.test.client 但不管它说没有。

【参考方案1】：

如果您在应用引擎上遇到此类导入错误，请务必检查您在 app.yaml 中的 skip_files。

例如：

skip_files:
  - ^(.*/)?.*/test/.*$

使“django/test”文件夹无法在您的开发环境中导入，并且该文件夹不会部署到应用引擎。
