我遇到了什么错误

zsh: command not found: rspec

我想做的事：

在我的 rails 应用程序中运行 $ rspec

到目前为止我做了什么

运行$ bundle
运行$ rails generate rspec:install
运行$ gem install rspec
运行$ sudo gem install rspec
运行$ bundle update rspec-rails
运行$ bundle binstubs rspec-core

我的 Gemfile

git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.7.4'

下面是我尝试使用 rspec 执行的规范文件

我的设置

红宝石 2.7.4p191
Rails 6.1.4

顺便说一句，使用$ bundle exec rspec 运行我的规范没有任何问题。我只是很好奇如何使用命令$ rspec 测试我的规格，这很可能在我作为 Rails 开发人员的整个职业生涯中都会用到。

【问题讨论】：

对于你想使用的 binstubs bin/rspec。

标签： ruby-on-rails ruby rspec rubygems tdd

【解决方案1】：

预先添加bundle exec 告诉bundler 在当前包的上下文中执行此命令。

尝试执行以下步骤：-

gem install rubygems-bundler

gem regenerate_binstubs

然后尝试使用rspec 而不使用bundle exec

【讨论】：

【解决方案2】：

如果您正在使用bundler，大多数时候您会希望在 de bundled 上下文中运行 gems；对于rspec，这始终是正确的。你应该使用bundle exec（你可以使用更短的别名），或者使用带有bin/rspec的binstub。

如果你将./bin添加到你的PATH环境变量中，你可以运行binstubs而不需要前缀bin/；所以你可以通过 rspec 调用 binstub。
