如何将Angular CLI升级到最新版本 [英] How to upgrade Angular CLI to the latest version

问题描述

使用ng --version我得到了:

@ angular/cli:1.0.0

@angular/cli: 1.0.0

这不是可用的最新版本.

which is not the latest release available.

由于我的系统上全局安装了Angular CLI，因此为了对其进行升级，我尝试:

Since I have Angular CLI globally installed on my system, in order to upgrade it I tried:

npm update angular-cli -g

但是它不起作用，因为它保持1.0.0版本.

But it does not work, because it stays to 1.0.0 version.

推荐答案

阅读了GitHub存储库上报告的一些问题之后，我找到了解决方案.

After reading some issues reported on the GitHub repository, I found the solution.

为了更新系统中全局安装的angular-cli软件包，您需要运行:

In order to update the angular-cli package installed globally in your system, you need to run:

npm uninstall -g @angular-cli
npm install -g @angular/cli@latest

根据您的系统，您可能需要在上述命令前面加上sudo.

Depending on your system, you may need to prefix the above commands with sudo.

此外，您很可能还希望更新本地项目版本，因为在项目目录中将其选择的优先级高于全局目录的优先级:

Also, most likely you want to also update your local project version, because inside your project directory it will be selected with higher priority than the global one:

rm -rf node_modules
npm uninstall --save-dev @angular-cli
npm install --save-dev @angular/cli@latest
npm install

更新CLI后，您可能也想更新Angular版本.

After updating your CLI, you probably want to update your Angular version too.

注意:如果要从较早版本更新到Angular CLI 6+，则可能需要阅读

Note: if you are updating to Angular CLI 6+ from an older version, you might need to read this.

编辑:此外，如果您仍使用cli的1.x版本，则需要将angular-cli.json转换为angular.json，可以使用以下命令进行操作:

Edit: In addition, if you were still on a 1.x version of the cli, you need to convert your angular-cli.json to angular.json, which you can do with the following command:

ng update @angular/cli --from=1.7.4 --migrate-only
