npm publish 发布一个 Angular 库的时候报错以及解决方法

我今天照着 npm 文件,打算把自己开发的 npm 库发布到公网上:

npm login 之后,使用命名行 npm config set registry=http://registry.npmjs.org, 遇到如下错误:

npm notice Beginning October 4, 2021, all connections to the npm registry - including for package installation - must use TLS 1.2 or higher. You are currently using plaintext http to connect. Please visit the GitHub blog for more information: https://github.blog/2021-08-23-npm-registry-deprecating-tls-1-0-tls-1-1/ npm ERR! code E426 npm ERR! 426 Upgrade Required - PUT http://registry.npmjs.org/my-lib

npm ERR! A complete log of this run can be found in: npm ERR! C:\Users\I042416\AppData\Roaming\npm-cache_logs\2021-10-17T02_40_15_408Z-debug.log

大意是,从2021年10月4日开始,所有前往 npm registry 的连接,都需要使用 TLS 1.2 了.

因此,我把命名行改成使用 https,旧的错误消息就消失了:

npm config set registry=http://registry.npmjs.org

然而我又遇到了新的错误消息:you do not have permission to publish "my-lib". Are you logged in as the correct user?

npm ERR! code E403 npm ERR! 403 403 Forbidden - PUT https://registry.npmjs.org/my-lib - You do not have permission to publish "my-lib". Are you logged in as the correct user? npm ERR! 403 In most cases, you or one of your dependencies are requesting npm ERR! 403 a package version that is forbidden by your security policy.

npm ERR! A complete log of this run can be found in: npm ERR! C:\Users\I042416\AppData\Roaming\npm-cache_logs\2021-10-17T02_44_36_666Z-debug.log

这个错误的原因是,我在 package.json 里使用的库名称为 my-lib, 这是我从 npm 教程里照抄的,已经有人将同名的库上传到 npm 仓库去了,因此我没有权限上传一个同名的库。

将 package.json 里的 name 字段修改即可:

之后就能够成功上传库了:
