npm has a lockfile which makes it infinitely better.
pip also has lock files
pip freeze > requirements.txtWould that just create a list of the current packages/versions without actually locking anything?
Yes, and all downstream dependencies
What do you mean? Nothing stops someone from manually installing an npm package that differs from package-lock.json - this behaves the same. If you
pip install -r requirements.txtit installs the exact versions specified by the package maintainer, just likenpm installthe only difference is python requires you to specify the "lock file" instead of implicitly reading one from the CWDAs I understand, when you update npm packages, if a package/version is specified in
package-lock.json, it will not get updated past that version. But running those pip commands you mentioned is only going to affect what version gets installed initially. From what I can tell, nothing about those commands is stopping pip from eventually updating a package past what you had specified in therequirements.txtthat you installed from.That's not a lockfile. This would be the equivalent of package.json
