Stack Overflow Asked by Floriane on December 6, 2020
When I try to build my project running the following command:
ng build --environment=prod --aot=false --output-path="..." --base-href="..."
You seem to not be depending on @angular/core
.
This is an error, however, I don’t understand why because before it worked well.
I tried to do this:
npm install @angular/core
But I get this error :
error at Error (native)
error { Error: EACCES: permission denied, chown ''
error at Error (native)
error errno: -13,
error code: 'EACCES',
error syscall: 'chown',
error Please try running this command again as root/Administrator.
verbose exit [ -13, true ]
I also tried to get rid of node_modules
, then make an install npm: but I get the same error.
And when I run the following command:
ng serve
I have another error:
The "@angular/compiler-cli" package was not properly installed. Error: Error: Cannot find module '@angular/compiler-cli'

I solved my issue with this same exact error with npm link
followed by ng serve
. I was told by another forum that this may be a result of an empty node_modules
folder. Please let me know if this works for you.

Stupid fix
Removing node_modules
and installing the packages again npm i
or yarn
worked for me!

I went down the list of installing the various dependencies as prompted in the terminal. I am running on Windows so I also installed windows Build Tools.
I ran ng serve and got "You seem to not be depending on "@angular/core" and/or "rxjs". This is an error."
Then ran
npm link
followed by
ng serve
Everything is now running. Not sure how much of what I did was necessary/redundant but I can now build Angular projects.

Faced the same issue and solved by executing the npm link
command.
When we run
npm link
in a module’s root directory, npm creates a symbolic link from our “global node_modules” directory to the local module’s directoryThe “global node_modules” directory is a special directory where all modules installed with
npm install -g
are stored. We can find the path to our global node_modules directory by runningnpm root -g

check if you have node_modules folder on project folder.
Answered by Wiwern95 on December 6, 2020
@Sunil Kumar Sahu is correct.
Using "ng link" means it connects your current application to your root/parent application that you have on your machine. When you run your application, any changes you make to the dependency will be reflected in the application.
After this, just run "ng serve".

Answered by Prakhar Aditya on December 6, 2020
faced same issue but solve such as by typing 1. npm link and then 2. ng serve if you still face issue then contact me...
Answered by Nadeem Ahmad on December 6, 2020
Run npm install
inside this project folder to install all dependencies.
Make sure you use the latest version of the CLI (upgrade guide below)
Run ng serve
to see the app in action (try npm start
in case ng serve
fails).
Run the below commands - only use "sudo" on Mac/ Linux.
sudo npm uninstall -g angular-cli @angular/cli
npm cache clean --force
sudo npm install -g @angular/cli
Delete node_modules
folder and package-lock.json
file from your project directory
Run the below commands in the given order-
npm install
npm install --save-dev @angular-devkit/build-angular
npm link

Not sure whether below approach will solve your problem or not, please try once.
I have also faced the same issue while executing below command.
D:My_Project>ng serve
Then I have followed below steps and it worked for me.
D:My_Project>npm link
D:My_Project>ng serve
If this is not working kindly let me know I will try to reproduce the error which you are getting and try to give you solution as soon as possible.
