我想在我的 nodejs 应用程序中安装 sequelize。

我收到此错误：-

npm install --save sequelize
npm WARN notsup Unsupported engine for sequelize@6.1.0: wanted: {"node":">=10.0.0"} (current: {"node":"8.10.0","npm":"6.14.4"})

我该怎么办？

【问题讨论】：

标签： node.js npm sequelize.js

【解决方案1】：

我已经解决了我的问题。我的 node(8.10.0) 不兼容安装 sequelize。所以我将它升级到最新版本。以下是使用n 将节点升级到最新版本的命令：-

sudo npm cache clean -f
sudo npm install -g n
sudo n latest

【讨论】：

非常糟糕。从不sudo npm
@Zach 为什么不用 sudo？他们正在尝试更新系统全局 (-g) 节点引擎。
