javascript - 在 Windows 上指定 Sequelize sqlite 路径

Question

我一直在 Linux 中使用 Sequelize 和 sqlite3 开发一个 Electron 应用程序，一切都运行良好。我像这样连接到数据库:

new Sequelize("sqlite:" + myPath);

其中 myPath 的形式为“/home/.../someDB.db”

但是，我尝试在 Windows 上运行我的项目，但遇到了连接数据库的问题。

如果我使用“someDB.DB”作为 myPath，我可以连接到数据库，但是当 myPath 是“C:...\someDB.db”形式的绝对路径时，我会收到错误:

我应该如何在 Windows 上使用 Sequelize 连接到 sqlite 数据库？

Answer 1

我意识到解决方案只是使用更详细的构造函数:

new Sequelize('', '', '', {
        dialect: 'sqlite',
        storage: myPath
      });
