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 production.py
)来自环境变量 ENV_ROLE
。以前,ENV_ROLE
如果未定义则默认设置为 development
,但我正在更改它以便 Django 抛出 ImproperlyConfigured
如果未定义则出错。
为了使测试通过,我需要在我们的 CircleCI 测试环境中定义 ENV_ROLE
环境变量。正在关注https://circleci.com/docs/2.0/env-vars/#setting-an-environment-variable-in-a-step ,我已将以下内容添加到 run
步骤:
- run:
environment:
ENV_ROLE: development
但是,我仍然从 CircleCI 收到此错误:
#!/bin/bash -eo pipefail
cd lucy-web
source venv/bin/activate
python manage.py compilescss --verbosity 0
python manage.py collectstatic --clear --no-input --verbosity 0
flake8
python manage.py test

During handling of the above exception, another exception occurred:

Django 项目修改了manage.py
:
#!/usr/bin/env python
import os
import sys
from dotenv import load_dotenv, find_dotenv
if __name__ == "__main__":
# Set environment variables from .env file
load_dotenv(find_dotenv())
# Determine which settings to apply (development, staging, or production)
from env import ENV_ROLE
os.environ.setdefault("DJANGO_SETTINGS_MODULE", f"lucy.settings.{ENV_ROLE}")
try:
from django.core.management import execute_from_command_line
except ImportError:
# The above import may fail for some other reason. Ensure that the
# issue is really that Django is missing to avoid masking other
# exceptions on Python 2.
try:
import django # noqa: F401
except ImportError:
raise ImportError(
"Couldn't import Django. Are you sure it's installed and "
"available on your PYTHONPATH environment variable? Did you "
"forget to activate a virtual environment?"
)
raise
execute_from_command_line(sys.argv)
其中 env.py
检查是否定义了 ENV_ROLE
环境变量,否则抛出 ImproperlyConfigured
错误:
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'.")
我不明白为什么 CircleCI 没有“获取”ENV_ROLE
环境变量?我的语法或对文档的理解有问题吗?
最佳答案
我在使用 circleCI + GAE 时遇到了类似的问题;我认为我在 .circleCI/config.yml 中设置的变量实际上从未进入应用程序,因为 GAE 运行的构建过程没有将它们传输进来。相反,我需要:
- 制作多个 app.yaml 文件(在我的例子中是 app-staging.yaml 和 app-prod.yaml)
更新 .circleci/config.yml 以在每个命令语句中使用它们,例如:
命令:gcloud app deploy app-staging.yaml
关于python - CircleCI 没有获取运行步骤中定义的环境变量?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/50614189/
