### Description

This command installs a package, and any packages that it depends on. If the
package has a package-lock or shrinkwrap file, the installation of dependencies
will be driven by that, with an `npm-shrinkwrap.json` taking precedence if both
files exist. See [package-lock.json](/configuring-npm/package-lock-json) and [`npm shrinkwrap`](/cli-commands/shrinkwrap).

#### Algorithm
To install a package, npm uses the following algorithm:
```bash
load the existing node_modules tree from disk
clone the tree
fetch the package.json and assorted metadata and add it to the clone
walk the clone and add any missing dependencies
dependencies will be added as close to the top as is possible
without breaking any other modules
compare the original tree with the cloned tree and make a list of
actions to take to convert one to the other
execute all of the actions, deepest first
kinds of actions are install, update, remove and move
```
For this `package{dep}` structure: `A{B,C}, B{C}, C{D}`,
this algorithm produces:

privately for itself. This algorithm is deterministic, but different trees may
be produced if two dependencies are requested for installation in a different
order.
See [folders](/configuring-npm/folders) for a more detailed description of the specific folder structures that npm creates.
### Limitations of npm's Install Algorithm
npm will refuse to install any package with an identical name to the
current package. This can be overridden with the `--force` flag, but in
most cases can simply be addressed by changing the local package name.
There are some very rare and pathological edge-cases where a cycle can
cause npm to try to install a never-ending tree of packages. Here is
the simplest case:
```bash
A -> B -> A' -> B' -> A -> B -> A' -> B' -> A -> ...
```
where `A` is some version of a package, and `A'` is a different version
of the same package. Because `B` depends on a different version of `A`
than the one that is already in the tree, it must install a separate
copy. The same is true of `A'`, which must install `B'`. Because `B'`
depends on the original version of `A`, which has been overridden, the
cycle falls into infinite regress.
To avoid this situation, npm flat-out refuses to install any
`name@version` that is already present anywhere in the tree of package
folder ancestors. A more correct, but more complex, solution would be
to symlink the existing version into the new location. If this ever
affects a real use-case, it will be investigated.
See [folders](/configuring-npm/folders) for a more detailed description of the
specific folder structures that npm creates.
