Running `ng build` in a specific directory
提问by JGrindal
I'm writing an automated build script that needs to run ng buildin a specific directory. My project has the following structure:
我正在编写一个需要ng build在特定目录中运行的自动构建脚本。我的项目具有以下结构：
project
├ build-script
└ project-client
└ package.json
ng buildis looking for the package.json file, but it can't find it in its current location. Is there a way I can direct ng buildto the subdirectory without doing a cd(since bash is a bit wonky about changing directories)? Essentially, I just need a way to tell ng buildto operate in a directory that I specify.
ng build正在寻找 package.json 文件，但在当前位置找不到它。有没有一种方法可以直接ng build到子目录而不做cd（因为 bash 改变目录有点不稳定）？本质上，我只需要一种方法来告诉ng build在我指定的目录中进行操作。
I have tried doing ng build ./project-client/but it is giving the error that "You have to be inside an angular-cli project in order to use the build command"
我试过这样做，ng build ./project-client/但它给出了“你必须在一个 angular-cli 项目中才能使用构建命令”的错误
Thanks.
谢谢。

When I need to go to certain directory just to run a script I usually use pushdand popd. Example:
当我需要去某个目录只是为了运行一个脚本时，我通常使用pushd和popd. 例子：
pushd /path/to/dir
ng build
popd
After this snippet is run your working directory (pwd) will remain unchanged.
运行此代码段后，您的工作目录 ( pwd) 将保持不变。

This is what I did.
这就是我所做的。
pushd angular-src && ng build && popd

Note: This answer is specific to Angular commands
注意：此答案特定于 Angular 命令
You can leverage the npm runcommand to run an Angular command while using the parameter --prefixto indicate the sub-directory.
您可以利用该npm run命令运行 Angular 命令，同时使用参数--prefix指示子目录。
Example 1: Original question (ng build)
示例 1：原始问题 ( ng build)
Since Angular already has a shortcut for this command, you can simply run
由于 Angular 已经有这个命令的快捷方式，你可以简单地运行
npm run build --prefix path\to\Angular\project
Example 2: Custom command (Eg: ng build --prod)
实施例2：自定义命令（例如：ng build --prod）
First, create a shortcut for this command in your package.jsonfile
首先，在您的package.json文件中为此命令创建快捷方式
{
"scripts": {
// "CMD-SHORTCUT": "custom-command"
"prod-build": "ng build --prod"
},
}
Then, run the new shortcut in the same way as example 1:
然后，以与示例 1 相同的方式运行新的快捷方式：
npm run prod-build --prefix path\to\Angular\project
