Unable to resolve sequelize package

Start with the migration:generate command and the package manifest, then compare the installed Sequelize package names with what sequelize-cli expects. Check database/sequelize.ts and models/item.model.ts to confirm the application uses Sequelize v7; done when the CLI resolves the package and generates a migration.

Hello. I am switching from Prisma to Sequelize v7 because Prisma does not support in-memory databases, which are useful in testing. I have defined Sequelize client and some models.
database/sequelize.ts:

import { Sequelize } from "@sequelize/core";
import { PostgresDialect } from "@sequelize/postgres";

import { Item, Listing, Terms, User } from "../models";

const sequelize = new Sequelize({
    dialect: PostgresDialect,
    database: "realestateexpress",
    user: "postgres",
    password: "root",
    host: "localhost",
    port: 5432,
    ssl: true,
    clientMinMessages: "notice",
    models: [Item, Listing, Terms, User]
});

export default sequelize;

models/item.model.ts:

import { CreationOptional, DataTypes, InferAttributes, InferCreationAttributes, Model, NonAttribute } from "@sequelize/core";
import { Attribute, NotNull, Unique, Table, BelongsToMany } from "@sequelize/core/decorators-legacy";

import { Listing } from ".";

@Table({ timestamps: false })
class Item extends Model<InferAttributes<Item>, InferCreationAttributes<Item>> {
    declare id: CreationOptional<number>;
    
    @Attribute(DataTypes.STRING)
    @Unique
    @NotNull
    declare name: string;

    @BelongsToMany(() => Listing, { through: "ListingItem" })
    declare listings?: NonAttribute<Listing[]>;

    public toString(): string {
        return this.name;
    }
}

export default Item;

I entered npx seqeulize-cli migration:generate in terminal and pressed enter, but the sequelize package cannot be resolved.

Yet the packages are literally installed packages.json:

{
  // ...
  "dependencies": {
    "@sequelize/core": "^7.0.0-alpha.42",
    "@sequelize/postgres": "^7.0.0-alpha.48",
    // ...
  },
  "devDependencies": {
    "sequelize-cli": "^6.6.5",
    // ...
  }
}
