rails app的env文件不在正确的位置？不被耙子看见

标签： ruby-on-rails ruby environment-variables

所以第一次使用rails我使用django

我尝试部署本地服务器但由于称为s3_bucket_name的密钥错误而失败，因为我没有包含变量的ENV文件

然后我得到了ENV文件并将其放在应用程序的根目录中。

然后我尝试启动应用程序而不去。

然后我运行了命令rake。

抱怨的是：

C:\Users\chris\Documents\suitsandtables>rake
rake aborted!
Gem::LoadError: You have already activated rake 12.1.0, but your Gemfile requires rake 12.0.0. Prepending `bundle exec` to your command may solve this.

然后我用--trace

运行它的建议

我得到了同样的回报。我究竟做错了什么？ 

C:\Users\chris\Documents\suitsandtables>bundle exec rake --trace
** Invoke default (first_time)
** Invoke test (first_time)
** Execute test
rake aborted!
KeyError: key not found: "S3_BUCKET_NAME"

env文件的内容如下，删除了敏感信息

S3_BUCKET_NAME=sat-paperclip-prod-heroku
AWS_ACCESS_KEY_ID= removed
AWS_SECRET_ACCESS_KEY= removed
AWS_REGION=us-east-1
GOOGLE_API_KEY= removed

我可以得到一些帮助吗

使用config/initializers/s3.rb中的Hash#fetch导致错误。这是一件好事。不要改变这一点。您的应用程序要求ENV值正常工作，如果未设置则会中断。 （config/initializers/内的所有内容都在启动时运行。此s3.rb文件不属于Rails核心，并且已由应用的作者添加。）

确保您的Gemfile已指定dotenv-rails。如果没有，请添加它（请参阅https://github.com/bkeepers/dotenv）并在Rails根目录中的终端中键入bundle。 （请注意，dotenv-rails也不属于Rails核心。）

您的Rails应用的根目录是包含文件Gemfile，Gemfile.lock等以及目录app/，bin/，config/的目录，db/，lib/等（即C:/Users/chris/Documents/suitsandtables/）。您可以跳转到Rails控制台（终端中的rails c或bundle exec rails c）并输入Rails.root来确认。

env文件应该命名为.env（因此名称为gem：dotenv），并且应该位于您的Rails根目录中。

您可以输入以下内容通过.env测试rails c文件：

# in the rails console
ENV                   # your whole environment in a Hash
ENV["S3_BUCKET_NAME"] # your bucket name

测试您正在寻找的所有环境值。 CaSe MaTtErS。

如果您正在运行任何Rails服务器或任务，请重新启动它们以获取这些更改。

键入bundle exec rake的预期结果是运行测试。如果您想自行运行应用，请使用rails s或bundle exec rails s。

P.S。不要git add/commit你的.env。它包含秘密。确保它是gitignore d。
