无法安装 sqlite3 gem

Question

我正在尝试运行 bundle 命令来安装 todo 应用程序的所有 gem。所有的 gem 都下载没有问题，但 sqlite3 gem 没有。我不知道以下是什么意思有人可以解释发生了什么以及如何解决吗？

安装带有原生扩展的 sqlite3 1.3.8

An error occurred while installing sqlite3 (1.3.8), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.8'` succeeds before bundling.

有什么问题，我该如何解决？ 谢谢。

Answer 1

bundle update sqlite3

看看这个gist

Answer 2

啊，好像是 2 月 4 日发布的 sqlite3 v1.4.0 gem 的问题。

在您的 gem 文件中提及以下 sqlite3 版本：

gem "sqlite3", "~> 1.3.6"

然后确保“捆绑安装”。

Answer 3

您需要用于编译 gem 的本机扩展的 SQLite3 开发头文件。您可以通过运行（可能使用sudo）来安装它们：

apt-get install libsqlite3-dev

之后，一定要运行

bundle update sqlite3
