當想要初始化一個php項目的時候 , 或者想要開發一個類庫給別人使用的時候
都需要一個composer.json文件
直接在項目目錄輸入 composer init 按照引導就可以生成了 , 詳細的引導解釋如下
This command will guide you through creating your composer.json config. # 1. 輸入項目命名空間 # 注意<vendor>/<name> 必須要符合 [a-z0-9_.-]+/[a-z0-9_.-]+ Package name (<vendor>/<name>) [root/test_composer]:yourname/projectname # 2. 項目描述 Description []:這是一個測試composer init 項目 # 3. 輸入作者信息，直接回車可能出現如下提示，有的系統可以直接回車，具體為什么？這里不詳細介紹 Invalid author string. Must be in the format: John Smith <john@example.com> # 3.1. 注意必須要符合 John Smith <john@example.com> Author [, n to skip]: John Smith <john@example.com> # 4. 輸入最低穩定版本，stable, RC, beta, alpha, dev Minimum Stability []:dev # 5. 輸入項目類型 Package Type (e.g. library, project, metapackage, composer-plugin) []:library # 6. 輸入授權類型 License []: Define your dependencies. # 7. 輸入依賴信息 Would you like to define your dependencies (require) interactively [yes]? # 7.1. 如果需要依賴，則輸入要安裝的依賴 Search for a package:php # 7.2. 輸入版本號 Enter the version constraint to require (or leave blank to use the latest version): >=5.4.0 # 如需多個依賴，則重復以上兩個步驟(7.1/7.2) Search for a package: # 8. 是否需要require-dev， Would you like to define your dev dependencies (require-dev) interactively [yes]? { "name": "dduan/test_compser", "description": "這是一個測試composer init 項目", "type": "library", "require": { "php": ">=5.4.0" }, "authors": [ { "name": "John Smith", "email": "john@example.com" } ], "minimum-stability": "dev" } # 9. 是否生成composer.json Do you confirm generation [yes]? # 現在安裝依賴項嗎 Would you like to install dependencies now [yes]?
