错误：通过 python 子进程调用启动 NodeJS 服务器时找不到模块

Question

我的setup.py文件中有这个脚本：

status = subprocess.check_output(["node", "/setupLocalAPI/app.js"])
print(status)

这应该调用节点服务器和 output 它是 output （这将是服务器已经启动的事实），但是每当我调用它时，我都会收到以下错误：

internal/modules/cjs/loader.js:979
throw err;
^

Error: Cannot find module 'c:\setupLocalAPI\app.js'

我的项目布局如下：

setup
    setup.py
    __init__.py
    setupLocalAPI
        app.js

Answer 1

使用相对路径./setupLocalAPI/app.js
