Question

这真令人沮丧。我正在尝试为node.js安装sequalize。我在本地成功安装了它，但是无法在全局上安装它（我收到以下权限被拒绝的错误：

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

我实际上并不真正希望将其全局安装，但是当在本地安装时，应该配置并初始化sequelize模块（通过键入 sequelize init：models和sequelize init：config < / strong>在终端中），出现以下错误：

-bash: sequelize: command not found

因此，我做了家庭作业，发现可以通过全局安装（-bash: sequelize: command not found）解决未找到命令错误，并且为了修复启用全局安装的错误，我更改了用户访问权限（Error: EACCES: permission denied, access '/usr/local/lib/node_modules' react ），但这并不能解决问题，我仍然无法获得许可。

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

Answer 1

您需要按以下步骤安装：

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

如果没有，请安装npx 初始化续集：

npx sequelize init

Answer 2

您需要安装

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

然后根据to documentation运行CLI。无需全局安装。

$ npx sequelize --help

Answer 3

我的问题的答案已解决，如vitamadio在评论中所述，在sudo的帮助下将其全局安装。所以answear就是这样安装的：

sudo npm install -g sequelize

然后：

sudo npm i -g sequelize-cli

Answer 4

按照下面的方法做应该没问题 npm install --save 续集 npm install --save sequelize-cli npx 续集初始化

如何解决“ sequelize：找不到命令”？
