我今天照著 npm 檔案，打算把自己開發的 npm 庫釋出到公網上：

npm login 之後，使用命名行 npm config set registry=http://registry.npmjs.org, 遇到如下錯誤：

> 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，從2021年10月4日開始，所有前往 npm registry 的連線，都需要使用 TLS 1.2 了.

因此，我把命名行改成使用 https，舊的錯誤訊息就消失了：

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

然而我又遇到了新的錯誤訊息：you do not have permission to publish "my-lib". Are you logged in as the correct user?

這個錯誤的原因是，我在 package.json 裡使用的庫名稱為 my-lib, 這是我從 npm 教程裡照抄的，已經有人將同名的庫上傳到 npm 倉庫去了，因此我沒有許可權上傳一個同名的庫。

將 package.json 裡的 name 欄位修改即可：

之後就能夠成功上傳庫了：
