npm 错误！代码 E401 npm ERR！密码不正确或丢失

Question

我的 Node 版本是 10.15.0，NPM 版本是 6.8.4 在将 npm 升级到 14.16.0 和 npm 到 7.6.2 后运行 npm install

收到此错误 -

npm ERR! code E401
npm ERR! Incorrect or missing password.
npm ERR! If you were trying to login, change your password, create an
npm ERR! authentication token or enable two-factor authentication then
npm ERR! that means you likely typed your password in incorrectly.
npm ERR! Please try again, or recover your password at:

npm ERR! If you were doing some other operation then your saved credentials are
npm ERR! probably out of date. To correct this please try logging in again with:
npm ERR!     npm login

Answer 1

在目录中C/Users/your-windows-username/

删除以下文件：

.cache
.package
.package-lock
.npmrc

之后，转到您的项目并在终端中运行以下命令

npm i

Answer 2

我在配置的公司注册表中遇到了同样的错误.npmrc

registry=https:<company-registry-url>

节点版本：19.1.0
NPM版本：8.19.3

解决方案：

执行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>.

.npmrc更新后

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

1. 如果您还没有这样做，请尝试在升级节点版本后运行命令“npm install”之前删除 package-lock.json 文件。

2. 如果这不起作用，请尝试删除本文中提到的 $HOME 目录中的 .npmrc 文件。
