tsx: command not found (MacOS)

Received after ingest command, npm run ingest:

gpt4-langchain-pdf-chatbot@0.1.0 ingest
tsx -r dotenv/config scripts/ingest-data.ts
sh: tsx: command not found

FIX:
ensure that you have ts-node and typescript installed as dev dependencies in your project:

npm install --save-dev ts-node typescript

In my case, install this package: https://www.npmjs.com/package/tsx

Update to lastest node, npm and yarn, then yarn install, then the question is gone.

Thanks for above answers, however, for those who are stuck executing the command npm install --save-dev ts-node typescript for a long time may try this method:

npm install --save-dev ts-node typescript --registry https://registry.yarnpkg.com
