如何在Windows上正确安装bootsnap

Question

我正在尝试使用rails安装程序在rails上安装ruby。 当我使用“rails new blog”来启动网页时，我不断遇到构建错误以构建本机扩展。 我在安装sqlite3时也遇到了类似的问题。 同样的问题也出现在我的笔记本电脑上。 （两个窗口）

到目前为止，我尝试下载此演练（ https://github.com/Shopify/bootsnap/issues/134 ），但在它告诉我执行脚本时卡住了。 我尝试在irb中运行给定的脚本，因为它逐行说和复制粘贴。 我也尝试过gem install bootsnap和gem install bundler --force 。 我还尝试从rails安装程序中分别下载2.5和2.6的不同版本的ruby。

Make sure that `gem install bootsnap -v '1.4.4' --source

In Gemfile:
  bootsnap

说实话，我没想到使用rails安装程序时会出现这样的问题我可以立即开始工作。

Answer 1

这适用于sqlite。

gem 'sqlite3', git: "https://github.com/larskanis/sqlite3-ruby", branch: "add-gemspec"

Bootsnap 2.3.3我无法运行它并升级了ruby版本。 如果你从下面的链接下载Ruby + Devkit 2.5.5-1（x64），我希望问题会有所改善。 Ruby 2.5.5

Answer 2

我使用Rails 5.2.3，ruby 2.3获得了相同的捆绑安装问题。 发现AngelofDawn最近的帖子对我有用：将gemfile中的bootsnap gem更改为

gem 'bootsnap', '=1.4.1', require: false

获取bootsnap的错误（退出代码2），不允许设置Rails服务器 。

还在寻找'为什么'

Answer 3

我用这个来解决它：

gem 'bootsnap', require: false
