Error: Cannot find module '@ionic/app-scripts&

问题:

I'm new to Ionic. I was following the Ionic documentation "get started", created a project sample named "super". The problem is that when I run the command line ionic serve in the project directory, it threw an error Error: Cannot find module '@ionic/app-scripts'

回答1:

app-scripts currently compatible with node 6 and 7. İf you installed node 8, then please uninstall and install node 6 stable version. This solved error and now i can use ionic 3, angular 4 . Take care!

回答2:

Try installing app-script from npm

npm i @ionic/app-scripts

回答3:

To get the latest @ionic/app-scripts, run the following command:

npm install @ionic/app-scripts@latest --save-dev

回答4:

do not downgrade the node version, update the version of "app-scripts":

To get the latest @ionic/app-scripts, please run:

npm install @ionic/app-scripts@latest --save-dev

I was facing same issue, here is what I did-

1. Removed node_modules from directory (Manually).
2. open project dir
3. run this command-

---

 npm install

That fixed those errors for me.

I had this issue , i solved it by deleting node_modules/ folder and ran the command npm installnow my app works

回答7:

I tried every non-downgrade solution mentioned in this thread, in all kinds of ways and none of them worked. With nothing left to lose, I went down the downgrade route (I used sudo apt-get purge --auto-remove nodejs to remove previous 8.x version and then installed the last stable ver on the 6.x branch using the nodesource ppa).

Still got the same errors trying to run in the original project folders, but then I created a new project and ionic serve worked just fine in that space.

FWIW, I did not need to run npm update or npm i @ionic/app-scripts afterwards, but I did find it necessary to adopt the habit of running commands with sudo in front (or you sudo -s into root account).

回答8:

I had the issue, solved by execute cnpm i @ionic/app-scripts.

回答9:

Just open a new terminal window/session. I could not figure it out, but it's probably related to env.

回答10:

None of the options worked for me. But I could make it work by updating node with npm update After this, the problem was solved and the application started. Good Luck.

回答11:

I had the same problem and here is what worked for me

I was trying to run the program using VSCode terminal, Instead I used the windows cmd and it ran perfectly. I think the error is in VSCode terminal, it cannot identify the app-scripts module inside the project. Maybe it will be fixed in a later update.

回答12:

You must create the project as administrator if you have mac or linux uses sudo, if you have windows run the console as administrator and create the project

回答13:

My issue was solved after run this script:

npm i @ionic/app-scripts
