NPM ERR代码E401：无法认证，需要：承载授权

Question

I downloaded a NodeJS application from GitHub and facing the following error when executing npm install.

npm ERR! code E401
npm ERR! Unable to authenticate, need: Bearer authorization_uri=https://login.windows.net/c1156c2f-a3bb-4fc4-ac07-3eab96da8d10, Basic realm="https://pkgsprodeus21.pkgs.visualstudio.com/", TFS-Federated

My Node version is 6.13.1 and NPM version is 6.13.4. Following is the content of package.json file:

{
  "name": "DemoApp",
  "version": "1.0.0",
  "description": "A social oasis for lovers of pizza.",
  "repository": "****",
  "main": "index.js",
  "scripts": {

I have been stuck at this issue since yesterday and still no luck finding the solution. Any help would be highly appreciated.

Answer 1

This is what worked for me.

First, delete the .npmrc file in your Users folder. This folder:

C:\Users\[your user name]

Then run this command in your project folder that has an .npmrc file in it:

npx vsts-npm-auth -config .npmrc

Answer 2

使用npm install --registry https://registry.npmjs.org而不是npm install

Answer 3

No need to delete the .npmrc file, the following worked for me

npm logout

Then

vsts-npm-auth -config .npmrc

Answer 4

I had this exactly same error and turned out it was an issue with personal access token (PAT). Renew your PAT and run vsts-npm-auth .

Answer 5

If you get E401 with a private npm registry after upgrading to npm v7, remove your package-lock.json and reinstall.

The registry url setting in .npmrc needs to match the http/https protocol in your package-lock.json exactly.

Answer 6

我解决了它运行这个命令：

npm logout/npm login

Answer 7

Delete old .npmrc file from user home directory and then run the following command

vsts-npm-auth -config .npmrc -T $HOME/.npmrc

Answer 8

I had the same error with our company registry configured in .npmrc

registry=https:<compnay-registry-url>

Node version: 16.10.0
NPM version: 7.24.0

Solution:

Execute npm login

$ npm login
npm notice Log in on https:<registry-url>
Username: xxxx
Password:
Email: (this IS public) (xxxx)
Logged in as xxx on https:<registry-url>.

After this .npmrc got updated with

//<registry-url>/:_authToken=xxxxx

Answer 9

I had the same issue, my discovery was as follows:

The application node.js version was 14.0 but the node version in my machine was 16.0 . I had to install the node the version 14.0 to resolve the issue.

To manage multiple node versions this tool is highly recommended.

• windows - Nvm for windows

• Linux - Nvm for Linux

Answer 10

I had the same issue caused by an expired token in the .npmrc file in my project directory. Sadly the error is very unspecific on what causes the auth error.

Answer 12

Worked for me:

• Delete the yarn.lock/package-lock.json files
• npm install

Answer 13

This issue comes from a wrong configuration in your .npmrc file. I had a slightly different error so I'm sharing it here.

In my case the exact error was:

Unable to authenticate, need: Bearer realm="<registry>", Basic realm="<registry>"

My npmrc file should connect to a private npm registry and looked like this:

registry=https://<private-registry>
//<private-registry>:_authToken=<token>
//<private-registry>:always-auth=true

The issue was that I needed to add the https:// protocol also to the second and third line and it worked. In the end it looked like this:

registry=https://<private-registry>
    //https://<private-registry>:_authToken=<token>
    //https://<private-registry>:always-auth=true

Answer 14

This worked for me. I just logged in again in NPM and problem was solved

npm login

After u write username and password execute again

mvn install

Answer 15

For me the the problem was in.npmrc file the key password needed to be changed to _password then npm install worked.

Answer 16

Using a Mac and Azure - it was because my Personal Access Token (PAT) had expired and it didn't let me know.

Open your.npmrc with your auth tokens in.

Go to your azure repo and click your profile and then personal access tokens.

Create a new token.

Open terminal and run:

node -e "require('readline').createInterface({input:process.stdin,output:process.stdout,historySize:0}).question('PAT> ',p => { b64=Buffer.from(p.trim()).toString('base64');console.log(b64);process.exit(); })"

Paste your PAT in and press Enter

Copy the Base64 encoded value into your.npmrc password.

Answer 17

使用命令better-vsts-npm-auth它应该可以工作。

Answer 18

Had the same error. In my case the initial project including package-lock.json file was composed with NodeJS version 12 and npm version 6. But trying to run npm install on my local machine with NodeJS version 16 and npm version 7 was causing this problem.

I still do not know what is causing this, but installing dependencies with initial version of NodeJS solved this problem. Run this command from root directory of your project, where package.json file located:

docker run --rm -it \
    -w /app \
    -v $PWD/:/app \
    node:12 \
    npm install

Answer 19

If you are trying to install any package from your private repo and you are getting this error with npm i package_name command then

1. remove your package-lock.json from the the directory where to tried to create the package from 
2. reinstall dependencies: npm i 

this will resolve the issue.
