如何解决“sequelize：找不到命令”？

Question

这是如此令人沮丧...我试图安装顺序node.js.我成功地在本地安装了它，但我不能全局安装它（我得到权限拒绝错误：

 \'../lib/node_modules/sequelize-cli/lib/sequelize\').

实际上，我并不希望它是全局安装的，但当它在本地安装时，应该配置并初始化sequelize模块（通过键入sequelize init:models

-bash: sequelize: command not found

所以我做了功课，发现命令未找到错误可以解决与全局安装（-bash：续集：命令未找到）和修复错误在启用全局安装我改变了我的用户访问（错误：EACCES：权限拒绝，访问'/usr/local/lib/node_modules'反应），但这并没有做的技巧，我仍然得到权限拒绝。

所以我的问题是如何运行sequelize init：模型

您需要安装

npm install --save sequelize
npm install --save sequelize-cli

您需要按以下方式安装：

npm install --save sequelize
npm install --save sequelize-cli

也安装npx，如果你没有它，然后初始化续集：

npx sequelize init

正如vitamadio在评论中所说，在sudo的帮助下，通过安装全球it解决了我的问题。所以answear是这样安装的：

sudo npm install -g sequelize 

然后：

sudo npm i -g sequelize-cli
