我猜這個問題是由 rails gem mimemagic 的版本過時引起的，所以我嘗試更新到最新版本，它仍然無法正常工作。

這是我的 ruby，Rails，mimemagic 版本

ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-darwin18]

rails -v
Rails 6.1.3.1

bundle info mimemagic
  * mimemagic (0.4.3)

Gemfile 中的信息

gem 'rails', '~> 6.1', '>= 6.1.0'
gem 'bundler', '~> 2.2', '>= 2.2.1.1'
gem 'mimemagic', '~> 0.4.3'

在 Gemfile.lock

 mimemagic (~> 0.4.3)

Answer 1

運行bundle update mimemagic為我工作

Answer 2

在 Gemfile 中將 mimemagic 的版本更改為 0.3.10

Mimemagic 似乎正在經歷更新？ 希望很快就會修復。 現在嘗試將 mimemagic 更改為以前的版本..

寶石文件：

 gem 'mimemagic', '~> 0.3.10'

Answer 3

運行bundle update會自動將你應用的每個依賴更新到最新版本
