Just installed rpos, and have an error on step 8 "node rpos.js"

that file "rpos.js" does not exist. It is not in the ~/rpos directories, nor do I see it here in the repository.

Did my install fail somewhere?

`laudix@RPi0-CameraUpstairs:~/rpos $ node rpos.js module.js:549 throw err; ^

Error: Cannot find module '/home/laudix/rpos/rpos.js' at Function.Module._resolveFilename (module.js:547:15) at Function.Module._load (module.js:474:25) at Function.Module.runMain (module.js:693:10) at startup (bootstrap_node.js:188:16) at bootstrap_node.js:609:3 `

arbitrarily trying a similarly named file also fails

laudix@RPi0-CameraUpstairs:~/rpos $ node rpos.ts /home/laudix/rpos/rpos.ts:29 import http = require("http"); ^^^^^^

in #54 @RogerHardiman says "check you have compiled rpos.ts into rpos.js"

here is my listing

I tried rerunning the install; still no file afterwards

laudix@RPi0-CameraUpstairs:~/rpos $ npm install npm WARN [email protected] requires a peer of typescript@~2.7.1 || >=2.8.0-dev || >=2.9.0-dev || ~3.0.0 || >=3.0.0-dev || >=3.1.0-dev || >= 3.2.0-dev || >= 3.3.0-dev but none is installed. You must install peer dependencies yourself.

[RogerHardiman]

The .ts file is written on Typescript. The install instructions have steps to compile (transpile) the Typescript into Javascript to give you the node.js file.

That is covered in Step 4 in the Readme file.

so. I wiped the SD card and reloaded the image (using a RPi Zero w/ camera attached) uname -a Linux raspberrypi 4.14.98+ #1200 Tue Feb 12 20:11:02 GMT 2019 armv6l GNU/Linux

Given Roger's insight, determined I hadn't copied the instructions correctly. After executing the 'missing' step: .................................................

Just to make this 'issue' complete... Once I used the instructions (including step 4) I am now able to detect and view my RPI from "ONVIF Device Manager v2.2.250"

[gitTinker]

Suggestion. Modify Step 4 layout to match the other steps so the required command is not overlooked. Specifically have "npx gulp" on a new line and indented, and prefix the comment with 'Note:"

[RogerHardiman]

Glad you got it working. Can you send over a Pull Request please and I can merge it in.

Thanks

[bendrexl]

Great suggestion. I think my pull request #76 addresses this, but feel free to review and suggest improvements there.
