#Install Yii
You can install Yii in two ways: using Composer or downloading an archive. It is recommended to use the former so that you can install new extensions or update Yii with just one simple command. After the standard installation of Yii, both the framework and a project template are downloaded and installed. A project template is a working Yii project that implements some basic features, such as login, contact form, etc. Its code is organized in a recommended way. Therefore, it can be suitable as a good starting point for your project. In this chapter and subsequent chapters, we will introduce how to install Yii and the so-called basic application template and how to implement new features on this template. Of course, Yii also provides other templates called advanced application templates, which are better suited for developing multi-level applications in a team development environment.信息： 這個(gè)基本的應(yīng)用程序模板是適合于開發(fā)90%的Web應(yīng)用程序。 它不同于高級(jí)的應(yīng)用程序模板主要地在如何使它們的代碼是 有組織的。 如果你是剛接觸Yii，我們強(qiáng)烈建議你堅(jiān)持使用簡(jiǎn)單并有足夠的功能的基礎(chǔ)的應(yīng)用程序模板。
Install via Composer
Install Composer
If you haven’t installed Composer yet, you can Install according to the method in getcomposer.org. In Linux and Mac OS X you can run the following command:curl -sS https://getcomposer.org/installer | php mv composer.phar /usr/local/bin/composerIn Windows, you need to download and run Composer-Setup.exe. If you encounter any problems or want to learn more about Composer, please refer to the Composer documentation. If you have Composer installed, make sure you are using the latest version. You can use the composer self-update command to update Composer to the latest version. In this guide, all composer commands assume that you have installed composer globally so that it can be used as a composer command. If you are using composer.phar in a local directory, you must adjust the example commands accordingly. If you have installed Composer before, make sure to use the latest version. You can update Composer by running composer self-update.
注意： 在安裝 Yii 期間，Composer 需要從 Github API 請(qǐng)求很多信息。 請(qǐng)求的數(shù)量取決于您的應(yīng)用程序所依賴的數(shù)量， 并 可能大于 Github API 速率限制。如果達(dá)到此限制，Composer 可能會(huì)要求您提供 Github 登錄憑據(jù)以獲取 Github API 訪問令牌。 在快速連接上，您可能比 Composer 能夠處理的時(shí)間早， 因此我們建議您在安裝 Yii 之前配置訪問令牌。 有關(guān)如何執(zhí)行此操作 的說明，請(qǐng)參閱 Composer documentation about Github API tokens。
Install Yii
After installing Composer, you can install the Yii application by running the following command under a web-accessible folder Templates:composer create-project --prefer-dist yiisoft/yii2-app-basic basicThis will install the latest stable version of Yii application templates in a directory called basic. You can choose a different directory name if needed.
信息： 如果 composer create-project 命令失敗，您也可以參考 Composer 文檔的疑難解答 部分中的常見錯(cuò)誤。修復(fù)錯(cuò)誤后， 您可以通過在 basic 目錄內(nèi)運(yùn)行 composer update 來恢復(fù)中止安裝。Tip: If you want to install the latest development version of Yii, you can use the following command instead, which adds a stability option:
composer create-project --prefer-dist --stability=dev yiisoft/yii2-app-basic basicPlease note that the development version of Yii should not be used production as it may break your running code.
Installation through archive file
Installing Yii through archive file includes three steps: 1. From yiiframework.com Download the archive. 2. Extract the downloaded file to a web-accessible folder. 3. Modify the config/web.php file and add a key to the cookieValidationKey configuration item (if you install it through Composer, this step will be completed automatically):// !!! 在下面插入一段密鑰（若為空） - 以供 cookie validation 的需要 'cookieValidationKey' => '在此處輸入你的密鑰',php Chinese website, A large number of free

They deeply understand Yii's underlying principles, participate in architectural design and technical decision-making, and use modular design to build flexible applications. 3. Senior developers pay attention to overall project planning and long-term development and play the role of mentor.
