本文介绍了环境变量的SECRET_KEY错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在通过TaskBuster Django 教程，其目的是帮助您为项目设置良好的开发设置.
I am working through the TaskBuster Django tutorial whose goal is to help in the process of setting up a good development setup for a project.
当我运行命令时回声$ SECRET_KEY
When I run the command echo $SECRET_KEY
在我的开发"环境或测试"环境中，我得到相同的输出，因此我相信我的$ ENVIROMENTS/bin/postactivate和predeativate变量设置正确.
In either my "Dev" environment or my "Test" environment I get the same output so I believe that my $ENVIROMENTS/bin/postactivate and predeativate variables are set up correctly.
我的base.py文件夹包含
my base.py folder contains
# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

def get_env_variable(var_name):

return os.environ[var_name]
except KeyError:
error_msg = "Set the %s environment variable" % var_name
raise ImproperlyConfigured(error_msg)
SECRET_KEY = get_env_variable('SECRET_KEY')

但是，当我尝试运行测试时，会得到此输出.
However, when I try to run the tests I get this output.

django.core.exceptions.ImproperlyConfigured: Set the SECRET_KEY environment variable
这使我相信密钥存在一些问题，但是我不清楚如何从此处进行故障排除.
This leads me to believe that there is some issue with the secret key but I"m unclear how to troubleshoot from here.
返回os.environ [var_name]返回错误的值吗?如何查看返回的内容，以便将其指向我希望返回的内容?我是否在解决这个问题的正确道路上?
is the return os.environ[var_name] returning the wrong value? How do I see what that is returning so I can point it to what I'd prefer it to return? Am I on the correct path to figuring this out?
这是我当前正在使用的测试文件
Here is the testing file I am using currently
from selenium import webdriver
from django.core.urlresolvers import reverse
from django.contrib.staticfiles.testing import LiveServerTestCase
class HomeNewVisitorTest(LiveServerTestCase):
def setUp(self):
self.browser = webdriver.Firefox()
self.browser.implicitly_wait(3)
def tearDown(self):
self.browser.quit()
def get_full_url(self, namespace):
return self.live_server_url + reverse(namespace)
def test_home_title(self):
self.browser.get(self.get_full_url("home"))
self.assertIn("TaskBuster", self.browser.title)
def test_h1_css(self):
self.browser.get(self.get_full_url("home"))
h1 = self.browser.find_element_by_tag_name("h1")
self.assertEqual(h1.value_of_css_property("color"),
"rgba(200, 50, 255, 1)")
推荐答案
您没有名为SECRET_KEY的环境变量.您需要在运行程序之前进行设置.
You don't have an environment variable named SECRET_KEY. You need to set it before you run your program.
在Unix上
export SECRET_KEY="password"
在Windows上
set SECRET_KEY="password"
值得注意的是，当您关闭终端时，该变量将消失.如果您想寻找它们，可以通过多种方法解决.
It's worth noting that the variable will disappear when you close the terminal. There are ways around that if you'd like to look for them.
