我正在尝试为Django项目运行CircleCI测试，其中manage.py确定要应用的settings.py版本（development.py，staging.py或{{ 1}}）来自环境变量production.py。以前，ENV_ROLE默认设置为ENV_ROLE，如果没有定义，但我正在更改它，以便Django在未定义的情况下抛出development错误。 / p>
为了使测试通过，我需要在CircleCI测试环境中定义ImproperlyConfigured环境变量。在https://circleci.com/docs/2.0/env-vars/#setting-an-environment-variable-in-a-step之后，我在ENV_ROLE步骤中添加了以下内容：
run但是，我仍然从CircleCI获得此错误：
- run:
environment:
ENV_ROLE: development

检查env.py环境变量是否已定义，否则会引发ENV_ROLE错误：
ImproperlyConfigured我不明白为什么CircleCI没有“拿起”import os
from django.core.exceptions import ImproperlyConfigured
try:
ENV_ROLE = os.environ['ENV_ROLE']
except KeyError:
raise ImproperlyConfigured(
"No 'ENV_ROLE' environment variable is defined. "
"Please define it as 'development', 'staging', or 'production'.")
环境变量？我的语法或对文档的理解是否有问题？

我使用circleCI + GAE遇到了类似的问题；我以为我在.circleCI / config.yml中设置的变量实际上并没有真正应用到应用程序中，因为GAE运行的构建过程没有将它们转移进来。相反，我需要：
更新.circleci / config.yml以在每个命令语句中使用它们，例如：
命令：gcloud应用程序部署app-staging.yaml

尝试在docker：部分中指定变量。
docker:
environment:
ENV_ROLE: development
这应该使用环境var启动您的容器。在容器可以访问它们之前，我必须测试一些版本的VAR。
如果您需要ENV_ROLE时可以看到这些变体中的任何一个，那么您可能也希望在其中添加您的变体。
