Here is the command I issued from Windows 7 on my Desktop PC:
npm install express
Here is the Error message:

How can I fix it?

This answer is probably a little bit too late, but I had the same problem. I fixed it by putting following settings in the npm config (located in %USERDATA%/.npmrc):
strict-ssl=false
registry=http://registry.npmjs.org
It requests the packages over plain http instead of the secure https.

Use these commands:
npm config set proxy http://username:password#host:port
npm config set https-proxy http://username:password#host:port
Or you may edit the ~/.npmrc file:
proxy=http://username:password#host:port
https-proxy=http://username:password#host:port
https_proxy=http://username:password#host:port

I had the same problem, turns out the proxy and/or https-proxy config pointed to the wrong proxy server.
The following commands set the proxy to the correct address:
npm config set https-proxy http://127.0.0.1:3128
npm config set proxy http://127.0.0.1:3128

List of npm registry

I want list of npm registries. I cannot install npm packages from https://registry.npmjs.org/, registry http://r.cnpmjs.org, http://registry.npmjs.eu, https://registry.npm.taobao.org/. They are all blocked. If you have any idea please make me aware of how can i install packages
Why its blocked?
maybe the right solution will be to use proxy like that (use your proxy its just an example)
npm config set proxy http://proxy.com:8000
or
npm config set https-proxy http://proxy.com:8000

How to install files using npm behind proxy?

While running the npm install command, I'm getting:
ERR 418 I m a teapot
I set a proxy but I'm not sure whether it is correctly parsed. I doubt that the proxy might be the reason. Can someone help me on this? I also ran npm config get proxy.
Try something like this:
npm config set proxy 213.169.158.34:8080
npm config set https-proxy 213.169.158.34:443
npm config set registry http://registry.npmjs.org/
npm instal

500 Internal Server Error: npm#latest

I have a problem with npm I can't get any package. For example running :
npm install -g npm#latest
gives :
npm ERR! code E500 npm ERR!
500 Internal Server Error: npm#latest
If I try to access https://registry.npmjs.org/ I get :
Fastly error: unknown domain.
Please check that this domain has been added to a service.
I looked into my /etc/hosts and nothing wrong there, any ideas ?

Below step resolve my npm registry issue. I hope same will be work for you.
Try to set npm registry using : npm config set registry https://registry.npmjs.org/
Check result of curl https://registry.npmjs.org/
Clear the cache: npm cache clean --force
Try to run npm install
From corporate network sometimes you won't be able to properly resolve registry.npmjs.org. To workaround the problem do the following.
dig registry.npmjs.org #1.1.1.1
Take any of the ip in the output and add to /etc/hosts
104.16.16.35 registry.npmjs.org
You should be good to go now.
I also faced the same issue.
Below solution worked for me at least:
comment out this part in windows hosts file
# 151.101.0.162 registry.npmjs.org
500 error indicates issue with the server. Yesterday I was facing this issue whenever I tried installing packages with npm. Upon searching a bit, I found status.npmjs.org. It's a page that shows the current status of npm registry. There was an outage due to DNS misconfiguration which was mentioned on the page.I kept checking the status page, and eventually there was a status update :
Update - This has now been resolved for most users and we will continue to monitor until it has cleared for everyone.

After this update, I was able to install packages without any issues.

Even I have updated npm config proxy and https-proxy to office n/w proxy. After this change only I was able to successfully run the npm install command.
How can I create-react-app with passing proxy parameters?
Thanks in advance
Your company's proxy must be not allowing you to access the setup.
Use the following two commands from command-promt
npm config set proxy http://proxy.company.com:8080
npm config set https-proxy http://proxy.company.com:8080
In place of "proxy.company.com", use your proxy address that you are using.
You can find your proxy at
IE Browser -> Internet Options -> Connections tab -> LAN Settings.

How should I set _auth in .npmrc when using a Nexus https npm registry proxy?

Context
My .npmrc file seems to be correctly read (checked with npm config ls -l both from command line and from Maven build).
the machine on which npm is run cannot connect directly to the net, it can only connect to a Nexus npm registry url. Therefore, proxy properties proxy and https-proxy are not set.
As access to Nexus is restricted, I have generated an access token from within Nexus.
Nexus security tokens are made from a username and a password which both contain characters such as / which usually have to be "url encoded"
as expected, with this configuration, when running npm install detects no proxy.
Nexus npm registry proxy seems to be correctly set (I can both access json files and download tgz files using a web browser after having connected using the token generated)
If I set registry to http://registry.npmjs.org/ and comment _auth, email, always-auth, strict-ssl properties, and add proxy and https-proxy configuration, npm install works as expected (but I won't be able to do it on target environment)
Content of .npmrc file
; Nexus proxy registry pointing to http://registry.npmjs.org/
registry = https://<host>/nexus/content/repositories/npmjs-registry/
; base64 encoded authentication token
_auth = <see question below>
; required by Nexus
email = <valid email>
; force auth to be used for GET requests
always-auth = true
; we don't want to put certificates in .npmrc
strict-ssl = false
loglevel = silly
Question
How should I generate the _auth property properly in order to have npm install work as expected?
I tried so far
base64Encode(<username>:<password>)
results in npm info retry will retry, error on last attempt: Error: socket hang up
base64Encode(urlencode(<username>:<password>))
results in npm info retry will retry, error on last attempt: Error: This request requires auth credentials. Run `npm login` and repeat the request.
base64Encode(urlencode(<username>):urlencode(<password>))
results in npm info retry will retry, error on last attempt: Error: socket hang up
When getting the socket hang up error I have the following stack trace:

Configure registry (its important doing this before configuring the authentication in step 2, because the authentication settings will be based on the registry):
npm config set registry="http://localhost:8081/repository/npm-internal/"
Configure authentication using a line like the following example:
npm config set _auth="$(echo -n 'username:password' | base64)"
Check the current configuration using the following:
npm config ls
Publish your npm package:
npm publish --registry http://localhost:8081/repository/npm-internal/
If you have authorization token you should not use username:password.
I suggest you:
Generate token
Delete your ~/.npmrc or rename it.
Make sure your env settings like $NPM_CONFIG_* are unset.
Verify that email and other settings are unset by using: npm config list
Log into the npm using: npm login --registry=https://nexus.whatever.registry/respository/npm-whatever-group/
Once you are logged - you are logged. The npm should generate a token for it in your ~/.npmrc. It will look like:
//nexus.whatever.registry/respository/npm-whatever-group/:_authToken=NpmToken.YOUR-LOVELY-TOKEN-IN-HEX
You can use that token in your project, CI pipeline, and other ones. Make sure in your project .npmrc there is:
//nexus.whatever.registry/respository/npm-whatever-group/:_authToken=NpmToken.YOUR-LOVELY-TOKEN-IN-HEX
email = <EMAIL_USED_FOR_TOKEN_GENERATION>
always-auth = true
registry = https://nexus.whatever.registry/respository/npm-whatever-group/
If you have problems with authentication/certs:
add env variable (also to your CI/CD pipline)
$NODE_EXTRA_CA_CERTS to point to /home/wherever/is/your/cert.pem
For CI/CD pipelines (like gitlabs or jenikins):
consider replacing actual values from your .npmrc project file with ${RELEVANT_ENV_VARIABLES}. This way you will make them less visible and always self-updating on change of pipline.
Hope this help.
After having looked at registry-client code I found the answer, here it is. I post it as it may help other people:
base64Encode(<username>:<password>)
By the way, there is an URL encoding, but it's authify.js that takes care of it.
The "socket hang up" problem I'm facing is due to the fact that if a proxy is set in Windows configuration, when launching npm from CLI (and not from a Maven build) all ```.npmrc`` proxy settings seem to be ignored while native proxy exclusions (for corporate urls) are ignored by npm. I'll open a ticket to report this weird behavior.
Before you run npm login, please follow the instructions below :
1) Create an ~/.npmrc file with the following contents:
registry=https://example.com/repository/npm-group/
email=username#example.com
always-auth=true
//example.com/repository/npm-group/:_authToken=
2) run `npm login`
# npm login
Username: firstname.lastname
Password:
Email: (this IS public) firstname.lastname#example.com
Logged in as firstname,lastname on https://example.com/repository/npm-group/.
Use the same password you use to login to example.com
I don't know about Nexus, but we use artifactory as an npm repo, and there I can create my auth token by calling base64encode(username:encryptedPassword) with encryptedPassword being the one I get from my personal artifactory profile.
Maybe this helps.
I just wrote a wrapper that stores the credentials in your systems keychain and provides them on the fly. Check out: https://github.com/Xiphe/npm_keychain_auth
