ruby-on-rails - bootsnap 出现错误（退出代码 2），不允许设置 Rails 服务器

问题描述

尝试测试基于 Rails 构建的网站，但不断收到错误消息，拒绝让我设置服务器。

收到错误后，我使用了 'gem install bootsnap -v '1.4.2' --source ' https://rubygems.org/ '，源为 Rubygems。同样的错误：

我的 gemfile 包括：

# Reduces boot times through caching; required in config/boot.rb
gem 'bootsnap', '>= 1.4.2', require: true

我确实看到 bootsnap 位于：C:\RailsInstaller\Ruby2.3.​​3\lib\ruby\gems\2.3.0\gems

有人知道如何摆脱这个吗？它也不在我的宝石清单上。

解决方案

I had the same problem and I'm also using railsinstaller on a windows computer.

To solve it, I updated my Gemfile like this :

#gem 'bootsnap', '>= 1.1.0', require: false
gem 'bootsnap', '= 1.4.1', require: false

Then run the command : bundle install in your project directory.
