Question

我使用mysql数据库在Node.js中完成了一个项目但是要启动node.js服务器，我创建一个简单地调用exec('set DEBUG=myapp:* & npm start')函数的php文件，它也可以在localhost中工作但是在我上传并尝试运行时在实时站点中，它会生成'npm-debug.log'和amp ;服务器无法启动npm-debug.log描述如下所述。

23 error Make sure you have the latest version of node.js and npm installed.
23 error If you do, this is most likely a problem with the myapp package,
23 error not with npm itself.
23 error Tell the author that this fails on your system:
23 error     node ./bin/www
23 error You can get information on how to open an issue for this project with:
23 error     npm bugs myapp
23 error Or if that isn't available, you can get their info via:
23 error     npm owner ls myapp
23 error There is likely additional logging output above.
24 verbose exit [ 1, true ]

要在Live Server上运行该命令，我们必须提供ssh身份验证，因此无需身份验证，它将不会触发任何命令。

为此我使用php的ssh2_exec()函数允许传递ssh凭据并建立连接会话然后执行任何命令。

感谢。

节点服务器开始在localhost中使用php工作，但在实时站点中它返回错误
