angularjs/cli- Ng 是命令无法正常工作 [英] angularjs/cli- Ng is command is not working as globle

问题描述

我已经安装了 angular/cli 但 ng 命令不能作为全局

I have installed the angular/cli but ng command is not working as global

C:\Projects>ng -v'ng' 不被识别为内部或外部命令，可运行的程序或批处理文件.

推荐答案

按照以下步骤开始使用 angular CLI.

Follow the below steps to start with angular CLI.

第一次更新节点版本:

1. 因此，首先通过键入命令 node -v 来检查您的节点版本.

2. 如果节点版本低于 6.x.x，则更新它，因为 angular CLI 要求节点版本高于 6.x.x.要更新节点版本，请运行以下命令.

1. So, first check your node version by typing command node -v.

2. If node version is lower than 6.x.x then update it because angular CLI requires node version to be higher than 6.x.x. To update node version run the below command.

nvm install <新版本>--reinstall-packages-from=<旧版本>

例如:nvm install 7.10.0 --reinstall-packages-from=5.1.0

然后运行命令:nvm use 7.10.0

在此运行命令后 npm install -g @angular/cli 安装 Angular CLI.

After this run command npm install -g @angular/cli to install Angular CLI.

额外:要将您的 angular 2 项目更新为 angular 4 项目，请运行以下命令:

Extra: To update your angular 2 project into angular 4 project run below command:

    * On Linux/Mac: npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-    
                     server,router,animations}@next --save server,router,animations}@next --save

     * On Windows: npm install @angular/common@next @angular/compiler@next @angular/compiler-cli@next @angular/core@next 
                   @angular/forms@next @angular/http@next @angular/platform-browser@next @angular/platform-browser-dynamic@next 
                   @angular/platform-server@next @angular/  router@next @angular/animations@next --save
