新手问题 rails new 的时候卡住了，萌新求教，卡在这里一天了
我想在 cli 中 rails new 一个练习用的小应用
执行到一半有报错
黄字让我 bundle install，敲完之后
然后我查了一天资料，零零散散的越看越头疼，不知道哪里出了问题，求指教，感谢
先通过 gem install sqlite3 来尝试安装先（缺少依赖必然会报错），然后上网搜索如何安装依赖的教程。一步步解决，这个问题以后装 mysql 的时候也有可能会遇到。
思路都差不多，我一般就是这样一步步去解决的。
先下载 slqite3 源码 https://www.sqlite.org/2020/sqlite-amalgamation-3330000.zip
然后解压到一个目录
然后 ggem install sqlite3 指定 include 文件目录 --with-sqlite3-include=你解压的目录
gem install sqlite3 -- --with-sqlite3-include=d:\sqlite-amalgamation-3320300
tablecell
回复
感谢大佬，我敲了下，然后有一些密钥错误，弄不太懂

@FishAndWhale sqlite3 解压到一个简单的目录 比如 d:\lite 不要带空格也不要有中文 安装完再删除也不影响
gem install sqlite3 -- --with-sqlite3-include=d:\lite\sqlite-amalgamation-3320300
如果觉得麻烦，你完全可以用 choco 安装 sqlite3，再安装 gem，现在用 windows 做 ror 未必就真的那么麻烦。只是资料不多。
