我已在我的.env文件中声明了此变量
WARRANTY_DETAILS_PER_MAKE = {"dacia" => {duration: 3, mileage: 100000}, "honda" => {duration: 3, mileage: 100000}, "infiniti" => {duration: 3, mileage: 100000}, "jaguar" => {duration: 3, mileage: 0}, "land-rover"=> {duration: 3, mileage: 100000}, "lexus" => {duration: 3, mileage: 100000}, "mazda" => {duration: 3, mileage: 100000}, "mitsubishi" => {duration: 3, mileage: 100000}, "nissan" => {duration: 3, mileage: 100000}, "subaru" => {duration: 3, mileage: 100000}, "suzuki" => {duration: 3, mileage: 100000}, "toyota" => {duration: 3, mileage: 100000}}
我在运行服务器时得到这个。

如果我将嵌套哈希值更改为字符串以进行调试，那么一切都会顺利运行。
是我的嵌套哈希的声明不正确还是dotenv的问题？
感谢您的帮助
答案 0 :(得分：1)
DotEnv does not parse除了简单的引用或未引用的值之外的任何其他内容，这与大多数shell处理ENV变量的方式一致。
LINE = /
\A
(?:export\s+)? # optional export
([\w\.]+) # key
(?:\s*=\s*|:\s+?) # separator
( # optional value begin
'(?:\'|[^'])*' # single quoted value
| # or
"(?:\"|[^"])*" # double quoted value
| # or
[^#\n]+ # unquoted value
)? # value end
(?:\s*\#.*)? # optional comment
\z
/x
如果你真的不得不使用Ruby哈希，你可以引用它并在其上调用eval：
# .env
FOO = '{ a: "b" }'
# call it:
foo = eval(ENV["FOO"])
或者使用JSON：
# .env
FOO = '{ "a": "b" }'
require 'json'
begin
JSON.parse(ENV["FOO"])
rescue JSON::ParserError => e
logger.error('Failed to parse ENV[FOO].')
logger.error(e.msg)
end
但看起来你可能正在使用错误的工具来完成工作，而YML配置文件可能更合适。
