Windows 10 - Failed at the @angular/cli@8.2.2 postinstall script
If you encounter an error during the postinstall script of the @angular/cli
package on Windows 10, there are a few potential solutions you can try:
Update Node.js and npm: Make sure you have the latest version of Node.js and npm installed on your machine. Outdated versions may have compatibility issues with certain packages. You can download the latest version of Node.js from the official website (https://nodejs.org) and update npm by running the following command in your command prompt or terminal:
cssnpm install -g npm@latest
Clear npm cache: Sometimes, issues can occur due to a corrupted npm cache. Try clearing the npm cache by running the following command:
cssnpm cache clean --force
Disable antivirus or security software: Antivirus or security software may interfere with the installation process. Temporarily disable any such software and try installing the
@angular/cli
package again.Run command prompt as Administrator: Launch the command prompt as Administrator to ensure you have the necessary permissions to install packages and execute scripts. Right-click on the command prompt icon and select "Run as Administrator."
Use a different package manager: If you are using npm, you can try using yarn as an alternative package manager. Install yarn globally by running the following command:
npm install -g yarn
Then, use yarn to install the
@angular/cli
package:sqlyarn global add @angular/cli@8.2.2
Check system environment variables: Verify that the system environment variables, such as
PATH
, are correctly configured. Ensure that the paths to Node.js and npm are added to thePATH
variable.
If none of the above solutions work, you can try updating your project to a newer version of the @angular/cli
package or seek assistance from the Angular community or support channels for further troubleshooting.
Remember to carefully read any error messages provided during the installation process as they can provide valuable information about the specific issue you're facing.
