安装@angularcli及异常处理

这次安装&＃64;angular-cli真的是头疼&＃xff0c;自动化安装的东西&＃xff0c;跑出了错误。无奈&＃xff0c;百度也没找到和我相似错误的博客&＃xff0c;只能自己尝试解决&＃xff0c;而你的环境和错误很有可能和我的不同&＃xff0c;具体还是要看日志去分析原因。

安装&＃64;angular/cli

环境

&＃64;angular/cli的环境要求是node 6.9.x 和 npm 3.x.x 以上的版本

node -v //查看node版本
npm -v //查看npm版本

如果符合&＃xff0c;就可以使用以下命令安装&＃64;angular/cli

npm install -g &＃64;angular/cli

但是我在这里一直报错&＃xff0c;而且满屏的错误信息简直摸不着头脑

尝试安装Angular对Typescript的依赖

先设置一下npm&＃xff0c;使用淘宝镜像

npm config set registry https://registry.npm.taobao.org
npm config set disturl https://npm.taobao.org/dist

然后安装Typescript依赖

npm install -g typescript typings

再次安装&＃64;angular/cli&＃xff0c;结果还是相同的错误日志

分析日志

冷静了一些&＃xff0c;开始分析日志&＃xff0c;逐步解决问题

npm WARN &＃64;angular-devkit/schematics&＃64;0.0.51 requires a peer of &＃64;angular-devkit/core&＃64;0.0.28 but none is installed. You must install peer dependencies yourself.
npm WARN &＃64;schematics/angular&＃64;0.1.16 requires a peer of &＃64;angular-devkit/core&＃64;0.0.28 but none is installed. You must install peer dependencies yourself.

可以看到需要手动安装&＃64;angular-devkit/core&＃64;0.0.28。而具体操作还要看日志信息&＃xff0c;也许你的问题和我并相同。

npm install -g &＃64;angular-devkit/core&＃64;0.0.28

如果不行&＃xff0c;那就按一下步骤操作

npm install -g &＃64;angular-devkit/schematics
npm install -g &＃64;angular-devkit/core&＃64;0.0.28 //事实上它是&＃64;angular/cli安装成功后在安装的

最终解决

到了这里&＃xff0c;我安装&＃64;angular-cli还是有问题的&＃xff0c;都有点想放弃了。有趣的是&＃xff0c;当我尝试着先安装了angular-cli&＃xff08;其实是运行错命令了&＃xff0c;只抛出了几个WARN&＃xff0c;但是成功的在npm的node_modules下&＃xff0c;而之前安装的&＃64;angular-cli&＃xff0c;node_modules下则根本就没有&＃xff09;&＃xff0c;再次安装&＃64;angular-cli就成功了
angular-cli和&＃64;angular/cli可不相同

npm install -g angular-cli
npm install -g &＃64;angular/cli
