• --lock (optional): Updates the Poetry lock file without installing the packages.
• --no-update (optional): Prevents updating the lock file when running the lock operation.
• --install (optional): Runs a Poetry installation to install all dependencies defined in pyproject.toml.

Examples

1. Import dependencies from requirements.txt into the default group:

   poetry import requirements.txt
   

2. Import dependencies from multiple requirements.txt files into specific groups:

   poetry import -g dev dev-requirements.txt -g test test-requirements.txt
   

3. Apply constraints from a constraints file during import:

   poetry import -c constraints.txt requirements.txt
   

4. Update the Poetry lock file after importing dependencies:

   poetry import --lock requirements.txt
   

5. Install all dependencies after importing:

   poetry import --install requirements.txt
