Question

GIT存储库中有一个角度项目。我想从原始系统（Mac OS-X Mojave 10.14.6）克隆它，安装所需的任何Angular组件，然后继续进行项目开发，但似乎无法使开发环境正常工作。 >

npm版本6.10.2 节点版本10.16.2

我克隆存储库并使用bash，使用package.json导航到目录。

$npm install
$ng serve

-bash：/ usr / local / bin / ng：没有这样的文件或目录

据我了解， npm install 应该安装我需要的任何东西。

这是我的package.json的内容。

Answer 1

您可以使用npm start代替ng serve。

为什么会这样？

因为在您的环境中全局范围内没有ng，所以您会收到该错误。您还可以运行npm install -g @angular/cli使其在全局范围内可用。

npm start为什么起作用？

在package.json内部，您可以看到script块中有一些命令。这样，nodejs将在本地范围（在文件夹node_modules/.bin中）找到二进制文件，您已经运行了npm install，因此ng将在本地范围内可用。

希望有帮助！

Answer 2

您需要全局安装Angular cli。

npm install -g @angular/cli

或

npm install -g @angular/cli@7.X

GIT中的角项目。不能在本地发展
