Node.js服务器未运行

Question

When I try to start the server through command prompt here is the error that I get:

The server was working fine earlier in the day.I am not able to understand the exact problem in this debug log. Your help would be appreciated.

Answer 1

By reading the error, looks like you don't have babel node tools installed. I googled it, looks like you can do this from the command prompt: npm install -g babel-cli.

edit for clarity

it looked like these lines happened several times:

10 verbose lifecycle web@0.0.0~start: CWD: C:\Users\Rohan-PC\Desktop\main  
11 silly lifecycle web@0.0.0~start: Args: [ '/d /s /c', 'babel-node tools/run start' ]  
12 silly lifecycle web@0.0.0~start: Returned: code: 1  signal: null  

To me that looked like npm was trying to load babel-node tools, but finding null when it looked for it.
