Ruby on rails 当我在Rails中创建一个新项目时，我遇到了这个错误

如何删除此错误？如何安装捆绑包

sqlite3.h is missing. Try 'port install sqlite3 +universal',
'yum install sqlite-devel' or 'apt-get install libsqlite3-dev'
and check your shared library search path (the
location where your sqlite3 shared library is located).

Gem files will remain installed in /var/lib/gems/1.9.1/gems/sqlite3-1.3.9 for inspection.

An error occurred while installing sqlite3 (1.3.9), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.9'` succeeds before bundling.

缺少sqlite3.h。尝试“端口安装sqlite3+通用”， “yum install sqlite devel”或“apt get install libsqlite 3 dev”

---

你试过这个吗？您可能需要在终端上运行

sudo

下的命令

sudo apt get install libsqlite3 dev

这应该可以：

sudo apt-get install sqlite3 libsqlite3-dev

bundle install

---

捆绑包已安装。问题在于SQLite。错误消息给出了一些建议。您尝试过这些吗？它就在错误消息中：尝试“port install sqlite3+universal”、“yum install sqlite devel”或“apt get install libsqlite3-dev”，结果如何？尝试时出现了什么问题？然后出现了什么错误？是否执行了

yum安装sqlite-devel

？
