Ruby 关于 Rails Failure/Error 关于所有示例
Ruby on Rails Failure/Error on all examples
我正在按照本指南构建 restful json api https://www.digitalocean.com/community/tutorials/build-a-restful-json-api-with-rails-5-part-one#project-setup
我已经跟踪了每一个步骤,直到模型区域(有 5 个区域,先决条件,项目设置,模型,控制器,结论)开始测试......
然而,当我尝试 运行 任何测试时,我所有的示例(其中 5 个)都失败了。

我真的很想了解修复此错误的方法,但我就是想不出来..
有任何想法吗 ?任何事情都会很有帮助

# Requires supporting ruby files with custom matchers and macros, etc, in
# spec/support/ and its subdirectories. Files matching `spec/**/*_spec.rb` are
# run as spec files by default. This means that files in spec/support that end
# in _spec.rb will both be required and run as specs, causing the specs to be
# run twice. It is recommended that you do not name files matching this glob to
# end with _spec.rb. You can configure this pattern with the --pattern
# option on the command line or in ~/.rspec, .rspec or `.rspec-local`.
#
# The following line is provided for convenience purposes. It has the downside
# of increasing the boot-up time by auto-requiring all files in the support
# directory. Alternatively, in the individual `*_spec.rb` files, manually
# require only the support files necessary.

好的,所以问题似乎是 ruby 和 rails 的版本。
出于某种原因 ruby 2.7.2 和 Rails 6.0.3.4 解决了我的问题。
当然需要修改GemFile
将 shoulda-matchers 和 rspec-rails 升级到最新版本对我有用
我也试过那个教程。我正在使用 Ruby 2.7.2 和 Rails 6.1.3,我需要更新 gem 'rspec-rails', '~> 4.0'
以解决该问题。
在 gem 文件中,如果 rspec 的版本小于 4,请尝试将其替换为最新版本或以下行。
gem 'rspec-rails', '~> 4.0'
对我有用
我解决了,在我的例子中,函数就像这里说的那样更新 gem rspec-rails 如下:
gem 'rspec-rails', ~>4.0 gem 'shoulda-matchers', '~> 5.0'
对于rails 6.1.4.1 没问题
