默認注冊表是 registry.npmjs.org。這可以在 bunfig.toml 中全局配置：

[install]
# 將默認注冊表設置為字符串
registry = "https://registry.npmjs.org"
# 設置令牌
registry = { url = "https://registry.npmjs.org", token = "123456" }
# 設置用戶名/密碼
registry = "https://username:password@registry.npmjs.org"

要配置特定組織的私有注冊表：

[install.scopes]
# 注冊表為字符串
"@myorg1" = "https://username:password@registry.myorg.com/"

# 帶有用戶名/密碼的注冊表
# 你可以引用環境變量
"@myorg2" = { username = "myusername", password = "$NPM_PASS", url = "https://registry.myorg.com/" }

# 帶令牌的注冊表
"@myorg3" = { token = "$npm_token", url = "https://registry.myorg.com/" }

.npmrc

Bun 還會讀取 .npmrc 文件，了解更多。
