Cannot read property 'Chart' of undefined

[donnrri]

Hi,

I cannot find many details as to why I am getting an error when trying to render a chart using react-chartjs. I'm using react v0.13 and webpack. I use the following code :

var LineChart = require("react-chartjs").Line; var React = require('react');

var LChart = React.createClass({

propTypes: { data: React.PropTypes.object }, render: function() {

return <LineChart data={this.props.data} options={this.props.options} width="600" height="250"/>

} });

module.exports = LChart;

but when I use this component within my app I get the error Cannot read property 'Chart' of undefined line 10 Chart.js . Is this a commonly found error and I am missing the solution somewhere ? Thanks for any comments

Did you specifically run "npm install chart.js" in your terminal when you installed react-chartjs?

I installed the chart.js, but the problems still exist

Make sure you install npm install chart.js --save not npm install chartjs --save I did that myself and got that error, realizing the package was wrong when trying to manually adjust it in the module.

I'm receiving this same error Uncaught TypeError: Cannot read property 'Chart' of undefined with chart.js@^1.1.1 installed. Any ideas?

Same issue. Excluding node_modules from babel-loader fixed it.

module: {
    loaders: [
      {
        test: /\.jsx?$/,
        exclude: /(node_modules)/,
        loader: 'babel-loader'
      }
    ]
  }

I had the same problem, but as @nickstanish suggested in his response, node_modules exclusion in Webpack solved this. Thanks.

In my case was the incorrect version installed 1.1. should be ^2.

UPDATE: The error was quite different Cannot read property 'bar' of undefined
