bootsnap 出现错误（退出代码 2），不允许设置 Rails 服务器

Question

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/' 源代码为 Rubygems。同样的错误：

我的 gemfile 包括这个：

# 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 gem list 上。

Answer 1

我也遇到了同样的问题。我正在使用 ruby​​ 2.3.0，rails 5.2.3。 为了解决这个问题，我更新了我的 Gemfile。

# it don't work....
# gem 'bootsnap', '>= 1.1.0', require: false
# gem 'bootsnap', '>= 1.4.2', require: false

gem 'bootsnap', require: false

然后捆绑安装就可以了！

Answer 2

我遇到了同样的问题，我也在 Windows 计算机上使用 railsinstaller。

为了解决这个问题，我像这样更新了我的 Gemfile：

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

然后在你的项目目录中运行命令：bundle install。
