| npm-doctor(1) -- Check your environments | ||
| ======================================================== | ||
|
|
||
| ## SYNOPSIS | ||
|
|
||
| npm doctor | ||
|
|
||
| ## DESCRIPTION | ||
|
|
||
| `npm doctor` runs a set of checks to ensure that your npm installation has | ||
| what it needs to manage your JavaScript packages. npm is mostly a standalone tool, but it does | ||
| have some basic requirements that must be met: | ||
|
|
||
| + Node.js and git must be executable by npm. | ||
| + The primary npm registry, `registry.npmjs.com`, or another service that uses | ||
| the registry API, is available. | ||
| + The directories that npm uses, `node_modules` (both locally and globally), | ||
| exist and can be written by the current user. | ||
| + The npm cache exists, and the package tarballs within it aren't corrupt. | ||
|
|
||
| Without all of these working properly, npm may not work properly. Many issues | ||
| are often attributable to things that are outside npm's code base, so `npm | ||
| doctor` confirms that the npm installation is in a good state. | ||
|
|
||
| Also, in addition to this, there are also very many issue reports due to using | ||
| old versions of npm. Since npm is constantly improving, running `npm@latest` is | ||
| better than an old version. | ||
|
|
||
| `npm doctor` verifies the following items in your environment, and if there are | ||
| any recommended changes, it will display them. | ||
|
|
||
| ### `npm ping` | ||
|
|
||
| By default, npm installs from the primary npm registry, `registry.npmjs.org`. | ||
| `npm doctor` hits a special ping endpoint within the registry. This can also be | ||
| checked with `npm ping`. If this check fails, you may be using a proxy that | ||
| needs to be configured, or may need to talk to your IT staff to get access over | ||
| HTTPS to `registry.npmjs.org`. | ||
|
|
||
| This check is done against whichever registry you've configured (you can see | ||
| what that is by running `npm config get registry`), and if you're using a | ||
| private registry that doesn't support the `/whoami` endpoint supported by the | ||
| primary registry, this check may fail. | ||
|
|
||
| ### `npm -v` | ||
|
|
||
| While Node.js may come bundled with a particular version of npm, it's the | ||
| policy of the CLI team that we recommend all users run `npm@latest` if they | ||
| can. As the CLI is maintained by a small team of contributors, there are only | ||
| resources for a single line of development, so npm's own long-term support | ||
| releases typically only receive critical security and regression fixes. The | ||
| team believes that the latest tested version of npm is almost always likely to | ||
| be the most functional and defect-free version of npm. | ||
|
|
||
| ### `node -v` | ||
|
|
||
| For most users, in most circumstances, the best version of Node will be the | ||
| latest long-term support (LTS) release. Those of you who want access to new | ||
| ECMAscript features or bleeding-edge changes to Node's standard library may be | ||
| running a newer version, and some of you may be required to run an older | ||
| version of Node because of enterprise change control policies. That's OK! But | ||
| in general, the npm team recommends that most users run Node.js LTS. | ||
|
|
||
| ### `npm config get registry` | ||
|
|
||
| Some of you may be installing from private package registries for your project | ||
| or company. That's great! Others of you may be following tutorials or | ||
| StackOverflow questions in an effort to troubleshoot problems you may be | ||
| having. Sometimes, this may entail changing the registry you're pointing at. | ||
| This part of `npm doctor` just lets you, and maybe whoever's helping you with | ||
| support, know that you're not using the default registry. | ||
|
|
||
| ### `which git` | ||
|
|
||
| While it's documented in the README, it may not be obvious that npm needs Git | ||
| installed to do many of the things that it does. Also, in some cases | ||
| – especially on Windows – you may have Git set up in such a way that it's not | ||
| accessible via your `PATH` so that npm can find it. This check ensures that Git | ||
| is available. | ||
|
|
||
| ### Permissions checks | ||
|
|
||
| * Your cache must be readable and writable by the user running npm. | ||
| * Global package binaries must be writable by the user running npm. | ||
| * Your local `node_modules` path, if you're running `npm doctor` with a project | ||
| directory, must be readable and writable by the user running npm. | ||
|
|
||
| ### Validate the checksums of cached packages | ||
|
|
||
| When an npm package is published, the publishing process generates a checksum | ||
| that npm uses at install time to verify that the package didn't get corrupted | ||
| in transit. `npm doctor` uses these checksums to validate the package tarballs | ||
| in your local cache (you can see where that cache is located with `npm config | ||
| get cache`, and see what's in that cache with `npm cache ls` – probably more | ||
| than you were expecting!). In the event that there are corrupt packages in your | ||
| cache, you should probably run `npm cache clean` and reset the cache. | ||
