如何在Windows上正確安裝bootsnap

Question

我正在嘗試使用rails安裝程序在rails上安裝ruby。 當我使用“rails new blog”來啟動網頁時，我不斷遇到構建錯誤以構建本機擴展。 我在安裝sqlite3時也遇到了類似的問題。 同樣的問題也出現在我的筆記本電腦上。 （兩個窗口）

到目前為止，我嘗試下載此演練（ https://github.com/Shopify/bootsnap/issues/134 ），但在它告訴我執行腳本時卡住了。 我嘗試在irb中運行給定的腳本，因為它逐行說和復制粘貼。 我也嘗試過gem install bootsnap和gem install bundler --force 。 我還嘗試從rails安裝程序中分別下載2.5和2.6的不同版本的ruby。

  bootsnap

說實話，我沒想到使用rails安裝程序時會出現這樣的問題我可以立即開始工作。

Answer 1

這適用於sqlite。

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

Bootsnap 2.3.3我無法運行它並升級了ruby版本。 如果你從下面的鏈接下載Ruby + Devkit 2.5.5-1（x64），我希望問題會有所改善。 Ruby 2.5.5

Answer 2

我使用Rails 5.2.3，ruby 2.3獲得了相同的捆綁安裝問題。 發現AngelofDawn最近的帖子對我有用：將gemfile中的bootsnap gem更改為

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

獲取bootsnap的錯誤（退出代碼2），不允許設置Rails服務器 。

還在尋找'為什么'

Answer 3

我用這個來解決它：

gem 'bootsnap', require: false
