This command will print the chain of dependencies causing a given package
to be installed in the current project.
If one or more package specs are provided, then only packages matching
one of the specifiers will have their relationships explained.
The package spec can also refer to a folder within ./node_modules
For example, running npm explain glob within npm's source tree will show:
glob@7.1.6
node_modules/glob
glob@"^7.1.4" from the root project
glob@7.1.1 dev
node_modules/tacks/node_modules/glob
glob@"^7.0.5" from rimraf@2.6.2
node_modules/tacks/node_modules/rimraf
rimraf@"^2.6.2" from tacks@1.3.0
node_modules/tacks
dev tacks@"^1.3.0" from the root project
To explain just the package residing at a specific folder, pass that as the
argument to the command. This can be useful when trying to figure out
exactly why a given dependency is being duplicated to satisfy conflicting
version requirements within the project.
Whether or not to output JSON data, rather than the normal output.
In npm pkg set it enables parsing set values with JSON.parse() before
saving them to your package.json.
Not supported by all npm commands.
workspace
Default:
Type: String (can be set multiple times)
Enable running a command in the context of the configured workspaces of the
current project while filtering by running only the workspaces defined by
this configuration option.
Valid values for the workspace config are either:
Workspace names
Path to a workspace directory
Path to a parent workspace directory (will result in selecting all
workspaces within that folder)
When set for the npm init command, this may be set to the folder of a
workspace which does not yet exist, to create the folder and set it up as a
brand new workspace within the project.
This value is not exported to the environment for child processes.
