问题
I just ran npm install --save sequelize pg pg-hstore in my project root directory and now I am unable to invoke sequelize init. I get the error: -bash: sequelize: command not found. What am I doing wrong?
回答1:
The reason is: sequelize is not installed globally on your cli. To get sequelize access to all your cli just do.
npm install -g sequelize-cli
The '-g' means global this will allow you to access sequelize command anywhere in your app directory.
After that you can do eg: sequelize model:generate --name User --attributes firstName:string,lastName:string,email:string,password:string

I would like to answer my own question. The global npm install path was wrong for my computer.
npm config get prefix
Then I ran to put the path where it should be. This problem gave me a lot of head aches. Hope it helps someone.
npm config set prefix /usr/local

Had the same issue, then noted that sequelize-cli is the way to go ahead.
npm install -g sequelize-cli

I prefer to avoid installing global npm packages. If you have sequelize as a dependency in your package.json, you can utilize sequelize-cli via npx.
$ npx sequelize-cli <command>.
For example, you could do $ npx sequelize-cli migration:generate --name add-a-column to create a migration file.

I had this problem and solved it by running
nvm install node --reinstall-packages-from=node
and then reinstalling
npm install -g sequelize-cli
Before doing this I had an unfortunate Node Version Manager setup. My computer was running something like version 10, but installing sequelize in the path used by version 8.
Now everything is updated and works.

if you want to use sequelize-cli without install it globally , you need to run it from node_modules folder in your root project. that is node_modules/.bin/sequelize. try to run node_modules/.bin/sequelize help for more information about sequelize command line
