Angular - cli error - apm@0.0.0 start: `ng serve -o`

[bhargav-18D]

Hi,

I am facing issues while starting the server. I tried installing the latest angular cli. As i have nodjs version 8.8.1, it is not compatible with it. So i installed angular cli 1.6.8.

***Logs****

Can we do away with cli modules and try to run the server?

[bhargav-18D]

An update. I deleted the node_modules, did an 'npm install' again, using cli - 1.6.8. On trying to run the "npm start", i get an error - "missing script: webpack"; "Cannot find module 'webpack/lib/node/NodeTemplatePlugin'" .

From the CLI documentation:

Both the CLI and generated project have dependencies that require Node 8.9 or higher, together with NPM 5.5.1 or higher.

You have:

2 info using npm@5.4.2 3 info using node@v8.8.1

Please update your version on node/npm. Then:

1) Delete your node_modules folder 2) Run 'npm install' 3) Run 'npm start'

Let me know if that works for you.

Other than Failed to exec start script, I'm not really seeing a specific error in this message. A few things to check:

1) Did you perform an npm install? Did that work without error?

2) Did you do anything else after the npm install, like a registry clean or an audit fix?

3) Were there any other messages that appeared before the log dump?

[thebadboy007]

1. When i try to install npm install i got some following error. npm WARN @angular/platform-browser-dynamic@7.0.2 requires a peer of @angular/compiler@7.0.2 but none is installed. You must install peer dependencies yourself. npm WARN ajv-keywords@3.4.1 requires a peer of ajv@^6.9.1 but none is installed. You must install peer dependencies yourself. npm WARN bootstrap@4.3.1 requires a peer of jquery@1.9.1 - 3 but none is installed.

2. Yah i did audit fix after that.

3. Schema validation failed with the following errors:

Those are not errors, they are warnings. Running audit fix is causing your problem. The code for this project is set up to work with a specific version. Running audit fix tries to update some of the versions and causes problems trying to run the code.

Try this:

1) Delete all of the folders/files.

2) Re-download or unzip the files.

3) Run npm install. Ignore all warnings and do NOT run audit fix.

4) Run npm start.

Let me know if that fixes things for you.

Thanks Deborah. Now it's working fine

A few things to check:

• Ensure you have a current version of npm
• run npm cache clear --force
• Reboot
• delete the node_modules and package-lock.json files
• Run npm install again.
