问题详情
上传图片配置在本地是正常的，push 到 heroku 之后就报错了，报错信息如下：
remote: !
remote: ! Precompiling assets failed.
remote: !
remote: ! Push rejected, failed to compile Ruby app.
remote:
remote: ! Push failed
remote: Verifying deploy...
在 stackoverflow 的解决方式如下：
config/application.rb
config.assets.initialize_on_precompile = false
修改之后再次 push 报错依然，运行如下命令查看一下 heroku 的日志
heroku logs --tail
看到如下报错信息：
2018-09-21T03:02:11.684933+00:00 app[web.1]: [4] ! Unable to load application: NameError: uninitialized constant CarrierWave::Storage::Fog
2018-09-21T03:02:11.685158+00:00 app[web.1]: bundler: failed to load command: puma (/app/vendor/bundle/ruby/2.4.0/bin/puma)
2018-09-21T03:02:11.685334+00:00 app[web.1]: NameError: uninitialized constant CarrierWave::Storage::Fog
stackoverflow 上的解决方式试过一遍了还是报这个错误

如下是我的相关文件
config/initializers/carrier_wave.rb
if Rails.env.production?
CarrierWave.configure do |config|
config.fog_credentials = {
# Amazon S3 的配置
:provider => 'AWS',
:aws_access_key_id => ENV['S3_ACCESS_KEY'],
:aws_secret_access_key => ENV['S3_SECRET_KEY'],
}
config.fog_directory = ENV['S3_BUCKET']
end
end
app/uploaders/picture_uploader.rb
class PictureUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
process resize_to_limit:[400, 400]
if Rails.env.production?
storage :fog
elsif Rails.env.development?
storage :file
end
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
def extension_white_list
%w(jpg jpeg gif png)
end
end
补充
在 push 前我还执行了 如下命令：
$ heroku config:set S3_ACCESS_KEY=<access key>
$ heroku config:set S3_SECRET_KEY=<secret key>
$ heroku config:set S3_BUCKET=<bucket name>
望各位大牛赐教，谢谢！
https://github.com/carrierwaveuploader/carrierwave/issues/2023 把 picture_uploader.rb 里的
if Rails.env.production?
storage :fog
elsif Rails.env.development?
storage :file
end
上面这段代码放到carrier_wave.rb里，并且在fog_credentials的下面。

if Rails.env.production?
CarrierWave.configure do |config|
config.fog_credentials = {
if Rails.env.production?
storage :fog
elsif Rails.env.development?
storage :file
end
# Amazon S3 的配置
:provider => 'AWS',
:aws_access_key_id => ENV['S3_ACCESS_KEY'],
:aws_secret_access_key => ENV['S3_SECRET_KEY'],
}
config.fog_directory = ENV['S3_BUCKET']
end
end
您的意思是这样吗？
这样的话有两个问题：
1、最顶端我已经有一个 if 判断了，再把这个 if 加进来是不是有点多余，我是不是直接把 storage :fog 加进来就好；
2、把它加到 config.fog_credentials 下是报语法错误的，是不是应该放在 前一行。
如下：
if Rails.env.production?
CarrierWave.configure do |config|
storage :fog
config.fog_credentials = {
# Amazon S3 的配置
:provider => 'AWS',
:aws_access_key_id => ENV['S3_ACCESS_KEY'],
:aws_secret_access_key => ENV['S3_SECRET_KEY'],
}
config.fog_directory = ENV['S3_BUCKET']
end
end
config.fog_credentials = {
# Amazon S3 的配置
:provider => 'AWS',
:aws_access_key_id => ENV['S3_ACCESS_KEY'],
:aws_secret_access_key => ENV['S3_SECRET_KEY'],
}
if Rails.env.production?
storage :fog
elsif Rails.env.development?
storage :file
end
我猜是这样
config.fog_credentials = {
# Amazon S3 的配置
:provider => 'AWS',
:aws_access_key_id => ENV['S3_ACCESS_KEY'],
:aws_secret_access_key => ENV['S3_SECRET_KEY'],
}
storage :fog
修改后的文件
app/uploaders/picture_uploader.rb
class PictureUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
process resize_to_limit:[400, 400]
storage :file
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
def extension_white_list
%w(jpg jpeg gif png)
end
end
config/initializers/carrier_wave.rb
if Rails.env.production?
CarrierWave.configure do |config|
config.fog_credentials = {
# Amazon S3 的配置
:provider => 'AWS',
:aws_access_key_id => ENV['S3_ACCESS_KEY'],
:aws_secret_access_key => ENV['S3_SECRET_KEY'],
}
storage :fog
config.fog_directory = ENV['S3_BUCKET']
end
end
修改后 再次 push 还是报一样的错误
看上面给的链接，其中有人回复https://github.com/carrierwaveuploader/carrierwave/issues/2023#issuecomment-310667421，不妨也参考下。

我改成了
if Rails.env.development?
storage :file
end
也将
require 'carrierwave/storage/fog'
加到对应文件中了
还是报错
