[Raushn]

please help me how to install npm
Always generating error to installing npm

[bvipul]

Most issues of npm install is solved by using correct version of node and npm, node v. 8.8.1 and npm v5.6 or above ..try with these settings

[Raushn]

node v.10.1.0
npm v5.6

[lawdoc71]

yarn install
Yarn run dev

[viralsolani]

I've checked with the latest node (10.4.1) and (npm 6.1.0). And found the issue. It is mostly because of node-sass has not found bindings. I've installed node-sass as the dependency.

To Resolve issue :

• remove node-modules
• remove package-lock.json
• run : npm install --save node-sass
• run : npm install
• run : npm run dev

Or take pull of develop branch and follow below steps.

• remove node-modules
• remove package-lock.json
• run : npm install
• run : npm run dev

Make sure you have full permission of node_modules folder.

Let me know if you still find issues.

[vrkansagara]

Just follow bellow steps to clean this issue.

1. Remove existing node_module folder

2. Run npm install

3. Run npm run development This will generate the mix manifest file.

4. (Optional) If you are running 127.0.0.1:8080 kind of web server then stop it first and start again.

[bvipul]

@Raushn I am going to close this issue, as you haven't replied for more than 15 days.

[vrkansagara]

The issue should be reopen as reporter doesn't confirmed yet.

[Raushn]
