How can I get npm start at a different directory?
提问by Blaise
I usually cdinto the app directory and then run npm start.
我通常cd进入应用程序目录，然后运行npm start.
It is my feeling that there ought to be some way to run npm startwith a path parameter. But, the npm start documentationcontains no such feature.
我的感觉是应该有某种方法可以npm start使用路径参数运行。但是，npm start 文档不包含此类功能。
I tried myself only to find npm start ./myappdoes not work. Is there a way to do that?
我试过自己才发现npm start ./myapp不起作用。有没有办法做到这一点？

This one-liner should work too:
这个单行也应该工作：
(cd /path/to/your/app && npm start)
Note that the current directory will be changed to /path/to/your/app after executing this command. To preserve the working directory:
请注意，执行此命令后，当前目录将更改为 /path/to/your/app。要保留工作目录：
(cd /path/to/your/app && npm start && cd -)
I used this solution because a program configuration file I was editing back then didn't support specifying command line arguments.
我使用这个解决方案是因为我当时正在编辑的程序配置文件不支持指定命令行参数。

Per this npm issue list, one work around could be done through npm config
根据此npm 问题列表，可以通过 npm config 完成一项解决方法
name: 'foo'
config: { path: "baz" },
scripts: { start: "node ./$npm_package_config_path" }
Under windows, the scriptscould be { start: "node ./%npm_package_config_path%" }
在窗户下，scripts可能是{ start: "node ./%npm_package_config_path%" }
Then run the command line as below
然后运行命令行如下
npm start --foo:path=myapp
