在带Spring的SpaceMac中使用RSpec

当我尝试在SpaceMac中运行RSpec测试时，我得到以下输出：

RSpec Compilation started at Tue Feb 21 14:14:30

spring rspec --options <path to my test>
WARN: Unresolved specs during Gem::Specification.reset:
  activesupport (>= 4.2)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
Version: 2.0.0

Usage: spring COMMAND [ARGS]

Commands for spring itself:

binstub         Generate spring based binstubs. Use --all to generate a binstub for all known commands. Use --remove to revert.
help            Print available commands.
server          Explicitly start a Spring server in the foreground
status          Show current status.
stop            Stop all spring processes for this project.

Commands for your application:

rails           Run a rails command. The following sub commands will use spring: console, runner, generate, destroy, test.
rake            Runs the rake command

我也可能不了解Spring在Rails上运行RSpec测试时的作用。

确保Spring正在运行，最新的spaces Mac应该自动检测

Spring.pid

，并相应地更改其命令

通过运行

spring服务器

或任何

bin/rails

命令

Spring仅在使用rspec测试运行程序时才受支持。

如果您有切换测试运行程序的项目，您可以通过在项目的根级别创建以下文件来为每个项目设置它们

# .dir-locals.el
((ruby-mode (ruby-test-runner . rspec)))

添加此答案，以防其他人也来这里寻求帮助

我不得不添加gem'spring commands rspec'，然后一切正常。

添加了一个关于有多个测试运行程序的注释。

# .dir-locals.el
((ruby-mode (ruby-test-runner . rspec)))
