问题
I have cloned an angular 4 project from git.
When I go to the root folder of the project and did ng serve.
I am getting following error. node_modules appears empty, you may need to run npm install
how can I fix the above error.
回答1:
Run npm install from the root of the project. If you're on a mac then you may want to run sudo npm install in case some of the package installations require elevated permissions. If it has submodules then leave a comment below and I'll update this answer to include how to deal with those. No use in confusing this answer with that unless you hit it.
回答2:
Open the directory where your project is using cd (Project name) Then run the command npm install After then you can easily run the ng g component command

Its saying node_module is empty means its not getting path.
1st Check path.Go to that path Using cd Like 'cd C:\Windows\UrProjectName'
Then run ng serve in node command prompt.
回答4:
In this situation you right click the app.component.html module then click a open in terminal.
After the terminal is opened in a bottom,you just type the command ng serve.
It can be worked properly.Each and every time you run the project in this method you avoid these types of errors.
