在不同的文件夹中安装包的依赖项?

I have the following directory structure:

我有以下目录结构:

/some_project
    source.js
    package.json

I would like to install the dependencies for some_project. I know I could cd into some_project and then run npm install

我想为some_project安装依赖项。我知道我可以把cd放入某个项目，然后运行npm安装。

But I was wondering if it's possible without changing the directory ? Something like

但是我想知道不改变目录是否可行?类似的

npm install some_project/package.json

You can use the npm install <folder> variant with the --prefix option. In your scenario the folder and prefix will be the same:

您可以使用npm install 变体和-prefix选项。在您的场景中，文件夹和前缀是相同的:

npm --prefix ./some_project install ./some_project

Update: Since the --prefix option exists, I now vote for @coudy's answer to this question. Original answer below:

更新:由于——前缀选项存在，我现在投票给@coudy对这个问题的回答。最初的回答如下:

No, npm will always install in the current directory or, with -g, in the system wide node_modules. You can kind of accomplish this with a subshell though, which won't affect your current directory:

不，npm将始终安装在当前目录中，或者在system wide node_modules中使用-g。你可以用一个子shell来完成，它不会影响你当前的目录:

(cd some_project && npm install)

The parentheses makes it run in a subshell.

圆括号使它在子shell中运行。
