引导时出现错误（退出代码2），不允许设置Rails Server [英] Getting error (exit code 2) for bootsnap, not allowing to set up Rails Server

问题描述

尝试测试基于Rails的网站，并不断出现错误，拒绝允许我设置服务器。

Trying to test a website built on Rails and keep getting an error that refuses to allow me to set up my server.

出现错误后，我使用了 gem install bootsnap -v'1.4.2'--source' https://rubygems.org/ '与来源为Rubygems。相同的错误：

After getting an error, I used 'gem install bootsnap -v '1.4.2' --source 'https://rubygems.org/' with the source as Rubygems. Same error:

我的gemfile包括：

My gemfile includes this:

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

我确实看到引导快照位于：C：\RailsInstaller\Ruby2.3.​​3\lib\ruby\gems\2.3.0\gems

I do see bootsnap located: C:\RailsInstaller\Ruby2.3.3\lib\ruby\gems\2.3.0\gems

有人会知道如何摆脱它吗？它也不位于我的宝石列表中。

Would anyone know how to get rid of this? It is not located on my gem list either.

推荐答案

我遇到了同样的问题，并且还在Windows计算机上使用railsinstaller

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

要解决此问题，我像这样更新了我的Gemfile：

To solve it, I updated my Gemfile like this :

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

然后在您的项目目录中运行命令：捆绑安装。

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