如何解决“sequelize：找不到命令”？

Question

这太令人沮丧了..我正在尝试为node.js 安装sequalize。我在本地成功安装了它，但无法全局安装它（我收到权限被拒绝的错误：

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

我实际上并不希望它全局安装，但是当在本地安装它并且应该配置和初始化sequelize模块时（通过在终端中输入 sequelize init:models & Sequelize init:config），我收到以下错误：

-bash: sequelize: command not found

所以我做了功课，发现命令未找到错误可以通过全局安装来解决（-bash：sequelize：命令未找到），并修复启用全局安装时的错误，我更改了我的用户访问权限（错误：EACCES：权限被拒绝，访问'/usr/local/lib/node_modules'反应），但这并没有解决问题，我仍然被拒绝权限。

所以我的问题是如何在终端中运行 sequelize init:models 和sequelize init:config 而不会找不到命令？

Answer 1

我的问题的答案是通过在 sudo 的帮助下全局安装它来解决的，正如 vitamadio 在评论中所说。所以答案是这样安装它：

sudo npm install -g sequelize 

然后：

sudo npm i -g sequelize-cli

Answer 2

您需要安装

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

然后根据文档您可以运行CLI。无需全局安装。

$ npx sequelize --help

Answer 3

您需要安装如下：

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

如果还没有 npx，请安装它 初始化续集：

npx sequelize init

Answer 4

按照下面的操作应该可以正常工作 npm install --save 续集 npm install --savesequelize-cli npx 续集初始化

Answer 5

尝试在终端中运行此命令。

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted

Answer 6

它对我来说是这样的。 第一次运行：

npm install -g Sequelize-auto

然后我收到以下错误（错误：请手动安装mysql2包），我通过运行解决了它：

npm 安装 mysql2 -g

我就完成了，希望对某人有帮助。
