Turned out to be an issue with Webpack just not resolving an import - talk about horrible horrible error messages        Had to change import DoISuportIt from  components DoISuportIt       To  notice the missing       import DoISuportIt from    components DoISuportIt

I m building a React server-side renderer and found this can also occur when building a separate server config from scratch  If you re seeing this error  try the following   Make sure your  quot entry quot  value is properly pathed relative to your  quot context quot  value  Mine was missing the preceeding  quot    quot  before the entry file name  Make sure you have your  quot resolve quot  value included  Your imports on anything in node modules will default to looking in your  quot context quot  folder  otherwise   Example  const serverConfig     name   server   context  path join   dirname   src    entry   serverEntry      server-entry js     output        path  path join   dirname   public        filename   server js       publicPath   public        libraryTarget   commonjs2     module        rules               resolveLoader        modules            path join   dirname   node modules            resolve        modules            path join   dirname   node modules

In my experience  this error was as a result of improper naming of aliases in Webpack  In that I had an alias named redux and webpack tried looking for the redux that comes with the redux package in my alias path   To fix this  I had to rename the alias to something different like Redux

In my case  to the very end of the webpack config js  where I should exports the config  there was a typo  export should be exports   which led to failure with loading webpack config js at all  const path   require  path     const config         mode   development       entry   quot   lib components Index js quot       output            path  path resolve   dirname   public            filename   bundle js             module            rules                                  test     js                    loader   babel-loader                   exclude  path resolve   dirname   quot node modules quot                                       pay attention to  quot export s  quot  here module exports   config

In my case  it was due to a broken symlink when trying to npm link a custom angular library to consuming app  After running npm link  authoring canvas  quot  authoring canvas quot    quot path to ui-authoring-canvas dist quot   It appear everything was OK but the module still couldn t be found   When I corrected the import statement to something that the editor could find Link  import  CirclePackComponent  from   authoring canvas lib circle-pack circle-pack component    I received this which is mention in the overflow thread   To fix this I had to   cd  usr local lib node modules packageName cd    rm -rf packageName In the root directory of the library  run   a  rm -rf dist b  npm run build c  cd dist  d  npm link   In the consuming app  update the package json with    quot packageName quot    quot file  path to local node module packageName quot  quot    In the root directory of the consuming app run npm link packageName
