Angular - 错误：生成 cmd ENOENT

Question

Hi I have problem when I generate angular - yo angular.

I'm all done. Running bower install & npm install for you to install the required dependencies. If this fails, try running the command yourself.

invoke angular:route invoke angular:controller:C:\\Users\\david\\AppData\\Roaming\\npm\\node_modules\\generator-angular\\route\\index.js create app\\scripts\\controllers\\about.js events.js:85 throw er; // Unhandled 'error' event ^ Error: spawn cmd ENOENT at exports._errnoException (util.js:746:11) at Process.ChildProcess._handle.onexit (child_process.js:1053:32) at child_process.js:1144:20 at process._tickCallback (node.js:355:11)

Anyone show me how to solve this issue? Thanks.

Answer 1

Im not sure why this error comes about, however i managed to run my Angular application by running with : ng serve instead of ng serve --open . Please not you will need to copy the url manually and place it in the browser afterwards which should be http://localhost:4200/

Answer 2

I got the same issue for windows 8 and tried several installations after doing changes to AppData/Roaming folder. None of the solutions worked for me. The issue is because of an environment variable of your system path is missing . Add "C:\\Windows\\System32\\" value to your system PATH variable.

Answer 4

I've got this issue after updating Angular CLI to 11.0.2 and I've been spent a lot of time to resolve this,

Apparently, I've tried the default port to serve my project and it served without any errors. which is http://localhost:4200/ but, I needed to run on http://localhost:8000/ So I did this....

First of all try remove node_modules from your directory and re-install npm packages. (I'm saying this because, some users got resolved the issue) to re-install npm packages, run

npm i 

or run below command

npm install

if this didn't work, try adding the port number to the angular.json file.

search for serve options in the json file.

then add your desired port number like this "port": 8000, (PS 'WorkspaceUI' means my project name and I've been trying to run on '8000' port. you can run on your own port number.) Then run your project using ng serve command. Thank you!

There are many guesses on different portal for this error and none of them works. Here is the solution - Run this command to install angular cli before performing anything -

npm install -g @angular/cli
