ruby-on-rails - 失败 'gem install sqlite3'

Question

当我运行rails new todo时，它显示如下(相关问题Make sure that 'gem install ~ ' succeeds before bundling)。

Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 read
server certificate B: certificate verify failed (https://rubygems.org/gems/sqlit
e3-1.3.10-x64-mingw32.gem)
An error occurred while installing sqlite3 (1.3.10), and Bundler cannot
continue.
Make sure that `gem install sqlite3 -v '1.3.10'` succeeds before bundling.

当我运行gem install sqlite3时，显示如下。

C:\Ruby21-x64>gem install sqlite3

按照我的教科书，我已经下载了 'sqlite-shell-win32-x86' ，创建了 'c:\sqlite3' 文件夹，在该文件夹中添加了 'sqlite3.exe' 并添加了路径 'c:\sqlite3'。

我该怎么办？我无法启动 RoR...

他说

checking for sqlite3.h... no
sqlite3.h is missing.

我找到了 sqlite3.h(它位于 sqlite-amalgamation 文件夹中)，所以我想接下来要做的就是将其放入正确的文件夹中。哪里是？ 我把sqlite3.h放在ruby.exe所在的文件夹中，但他仍然说sqlite3.h丢失。。

您缺少 gem 所需的系统依赖项。

sudo apt-get install sqlite3 libsqlite3-dev
