DedupePlugin fails: No template for dependency: TemplateArgumentDependency

[alansouzati]

Hi folks,

Great job with Webpack, this framework is really helping my project to succeed. I'm using version 1.8.11 through gulp-webpack and after I've added react-intl in my project this problem started to happen:

Error: No template for dependency: TemplateArgumentDependency

After some investigation and checking out some suggestions in the webpack Gitter chat, I decided to remove the Dedupe Plugin and then everything works again, but my bundle size has increased significantly.

Any ideas on how to make the DedupePlugin work again? If I get any pointers I could try to solve the issue myself. Any help here is much appreciated.

Suddenly started getting the same issue, only I'm using 1.4.15 and haven't updated anything:

node_modules/gulp-webpack/node_modules/webpack/lib/NormalModule.js:116
        if(!template) throw new Error("No template for dependency: " + dep.Class.nam
                            ^
Error: No template for dependency: TemplateArgumentDependency

I'm guessing some dependency updated with breaking changes without bumping the version enough, but that's just a stab in the dark because I'm having a lot of trouble tracking down the source of this sudden error.

Having a similar issue
Running webpack works, however, webpack-dev-server breaks with the "No template.." error, and removing the dedupe plugin fixes it

I am getting the same issue. Replicating it is kinda hard.

./foo/index.js

'use strict';

function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { 'default': obj }; }

var _react = require('react');

var _react2 = _interopRequireDefault(_react);

// import ReactDOM from 'react-dom';

/bar/index.js

import Foo from './../foo/index.js';

Where foo and bar are separate modules.

Using this webpack.config.js:

var webpack = require('webpack'),
    path = require('path'),
    ExtractTextPlugin = require('extract-text-webpack-plugin'),
    devServer;

devServer = {
    contentBase: __dirname + '/endpoint',
    colors: true,
    quiet: false,
    noInfo: false,
    publicPath: '/',
    historyApiFallback: true,
    host: '127.0.0.1',
    port: 8000,
    hot: true
};

module.exports = {
    devtool: 'source-map',
    debug: false,
    devServer: devServer,
    context: __dirname + '/src',
    entry: {
        app: [
            './'
        ]
    },
    output: {
        path: __dirname + '/endpoint',
        filename: '[name].js',
        publicPath: devServer.publicPath
    },
    plugins: [
        new ExtractTextPlugin('app.css', {
            allChunks: true
        }),
        new webpack.optimize.OccurenceOrderPlugin(),
        new webpack.OldWatchingPlugin(),
        // new webpack.NewWatchingPlugin(),
        // https://github.com/webpack/docs/wiki/optimization#deduplication
        new webpack.optimize.DedupePlugin(),
        new webpack.NoErrorsPlugin()
    ],
    module: {
        loaders: [
            {
                test: /\.js$/,
                include: path.resolve(__dirname, './src'),
                loader: 'babel'
            }
        ]
    },
    resolve: {
        extensions: [
            '',
            '.js'
        ]
    }
};

babel-loader is required.

Removing new webpack.optimize.DedupePlugin() makes it work.

[curiouslychase]

Has anyone figured out why this is causing this issue? I'm getting the same issue but deduping would be awesome rather than just getting rid of the plugin.

[gajus]

Since this is happening only when using webpack-dev-server, a simple solution would be to include the plugin only when running webpack command.

[miaojing]

I'm getting the same issue, I use it in webpack-dev-middleware.

[caccialdo]

Getting the same error without using webpack-dev-server here. We deactivated the plugin but it would be nice to be able to use it.

[caccialdo]

rm -rf node_modules && npm i solved the issue. Please ignore my previous message.

I was having the same issue using Webpack 1.11.0. Upgrading to 1.12.9 seems to have fixed the problem. You folks should try again with a newer version and see if this issue can be closed.

[tribou]

I just hit this issue after adding twilio@^2 to my project which, in turn, required adding json-loader. Commenting out the Webpack.optimize.DedupePlugin works as a temporary fix. Just updated to webpack@1.12.14 as well but still no luck.

Did anyone ever find the root cause to this issue?

@tribou #959 (comment)

[tribou]

Thanks!

For anyone encountering this in the future, the comment referenced above says:

Error: No template for dependency: TemplateArgumentDependency happens when you have multiple webpack copies installed and used the DedupePlugin from a different copy.

I was using a serverless-webpack-plugin which had it's own webpack dependency it was using to bundle files. However, I had manually installed and required webpack in my project's webpack config as well (like you normally would with webpack). Consequently, when I removed my explicitly installed version of webpack with npm rm --save-dev webpack, the plugin was able to require it's own scoped webpack dependency instead which worked.

I'll alert the serverless-webpack-plugin repo to this issue to figure out how to make it easier to use in the future.

[mouhsinelonly]

did anyone fix this issue , everything works fine on my locale machine but when i try to compile on the server i receive this error
i've deleted node_modules multiple times and did npm install,but with no luck

[tribou]

Do you have any dependencies that are requiring webpack? Also, did you install webpack globally on your local machine?

[BerndWessels]

@tribou I'm seeing this too

ERROR in chunk app [entry]
[name].bundle.js
No template for dependency: TemplateArgumentDependency

But unfortunately there are no other useful information and I removed the Dedupe Plugin already.

Any idea what can I do to fix it?

Everything is locally installed.

[tribou]

The issue I encountered above was that a dependency I was using didn't have webpack correctly listed as a peerDependency. Maybe verify that any webpack-related plugins or dependencies in your repo have webpack listed as a peer dep.

[BerndWessels]

@tribou Thanks, I will look at that too.

But I guess my problem is a bit weirder - since exactly the same project copied to another machine (including node_modules) works fine on one machine but has this error on the other machine.

[arlair]

In case this helps anyone, I think my issue was related to using npm link. See here: http://stackoverflow.com/questions/37915849/webpack-chunkrendererror-no-template-for-dependency-templateargumentdependenc/

[bebraw]

I'm closing this as there's no DedupePlugin in webpack 2 anymore.
