package-lock.json不是用npm install创建的

Question

Am starting a new project with npm init but the package-lock.json was not created. I'm also not quite sure what the importance of this file is, cos everything seems to run like normal.

Answer 1

From the docs

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.

Basically you won't see it unless you do a npm install [module-name] . Since npm init just initializes the project.
