### Synopsis
|
|
|
|
```bash
|
|
npm explain <folder | specifier>
|
|
|
|
alias: why
|
|
```
|
|
|
|
### Description
|
|
|
|
This command will print the chain of dependencies causing a given package
|
|
to be installed in the current project.
|
|
|
|
Positional arguments can be either folders within `node_modules`, or
|
|
`name@version-range` specifiers, which will select the dependency
|
|
relationships to explain.
|
|
|
|
For example, running `npm explain glob` within npm's source tree will show:
|
|
|
|
```bash
|
|
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.
|
|
|
|
```bash
|
|
$ npm explain node_modules/nyc/node_modules/find-up
|
|
find-up@3.0.0 dev
|
|
node_modules/nyc/node_modules/find-up
|
|
find-up@"^3.0.0" from nyc@14.1.1
|
|
node_modules/nyc
|
|
nyc@"^14.1.1" from tap@14.10.8
|
|
node_modules/tap
|
|
dev tap@"^14.10.8" from the root project
|
|
```
|
|
|
|
