【问题描述】：

我的测试在本地通过，实际上在 Github Actions 上它也显示“运行 8 个测试”，然后是“OK”（我有 8 个）。但是，由于回溯中出现奇怪的错误，测试阶段失败了。

Traceback (most recent call last):
  File "/opt/hostedtoolcache/Python/3.9.9/x64/lib/python3.9/site-packages/django/db/backends/utils.py", line 82, in _execute
    return self.cursor.execute(sql)

    return Database.Cursor.execute(self, query)
sqlite3.OperationalError: near "SCHEMA": syntax error

The above exception was the direct cause of the following exception:

这些都是默认的 Django 文件，我没有弄乱它们。我真的不知道该怎么办，互联网搜索没有任何帮助。

【问题讨论】：

您的网站是否托管在 heroku 上？因为在heroku中你不能使用sqlite。
是的，但它工作正常。数据库和图像都正常工作；唯一的问题是 Github Actions 中的测试。

【解决方案1】：

刚刚遇到同样的问题。对我来说，我的项目 settings.py 中有 django_heroku。看起来，基于您的应用程序正在使用的 cmets。我在 settings.py 中有这样的东西：

import django_heroku
django_heroku.settings(locals())

更改为以下内容，使其不在 github 操作上使用 django_heroku：

if os.environ.get('ENVIRONMENT') != 'github':
    import django_heroku
    django_heroku.settings(locals())

然后在工作流文件中声明一个环境变量，我有这个：

jobs:
  build:

    runs-on: ubuntu-latest
    strategy:
      max-parallel: 4
      matrix:
        python-version: [3.7, 3.8, 3.9, '3.10']
    env: 
      DJANGO_SECRET_KEY: "someKey"
      ENVIRONMENT: github

注意：这是假设您已设置环境变量。我知道有不同的方法，因此根据它们的设置方式，您可能必须更改它们的访问方式
