"Cannot find module ..." Issues after update to 3.2.0?

[ptrwllrt]

node v6.10.2
npm 5.0.4

Error: Cannot find module './xregexp' from '/var/www/nodefrontend/current/node_modules/xregexp'
Error: Cannot find module './addons/unicode-properties' from '/var/www/nodefrontend/current/node_modules/xregexp'
Error: Cannot find module './addons/matchrecursive' from '/var/www/nodefrontend/current/node_modules/xregexp'
Error: Cannot find module './addons/build' from '/var/www/nodefrontend/current/node_modules/xregexp'
Error: Cannot find module './addons/unicode-categories' from '/var/www/nodefrontend/current/node_modules/xregexp'
Error: Cannot find module './addons/unicode-scripts' from '/var/www/nodefrontend/current/node_modules/xregexp'
Error: Cannot find module './addons/unicode-base' from '/var/www/nodefrontend/current/node_modules/xregexp'
Error: Cannot find module './addons/unicode-blocks' from '/var/www/nodefrontend/current/node_modules/xregexp'

usage:

import xregexp from 'xregexp';
...
const unicodeWord = xregexp('[\\p{L}\\.\\-\\ ]{1,}');
return unicodeWord.test(str);
...

The installed npm package contains a xregexp-all.js on the root level which is mentioned in the package.json as "main".
However this file tries to require some modules like this:

...
},{}],8:[function(require,module,exports){
var XRegExp = require('./xregexp');

require('./addons/build')(XRegExp);
require('./addons/matchrecursive')(XRegExp);
require('./addons/unicode-base')(XRegExp);
require('./addons/unicode-blocks')(XRegExp);
require('./addons/unicode-categories')(XRegExp);
require('./addons/unicode-properties')(XRegExp);
require('./addons/unicode-scripts')(XRegExp);
...

These requires are broken because the actual files are stored in src/.
So for this particular file the following would be correct.

...
},{}],8:[function(require,module,exports){
var XRegExp = require('./src/xregexp');

require('./src/addons/build')(XRegExp);
require('./src/addons/matchrecursive')(XRegExp);
require('./src/addons/unicode-base')(XRegExp);
require('./src/addons/unicode-blocks')(XRegExp);
require('./src/addons/unicode-categories')(XRegExp);
require('./src/addons/unicode-properties')(XRegExp);
require('./src/addons/unicode-scripts')(XRegExp);
...

Something is fishy here. Did the packaging for the release went wrong? Am I using the module wrong?

I'm seeing the same problem. Seems Browserify fails to locate the module "xregexp", and the error message readsError: Cannot find module 'xregexp' from ....

I'm not sure if the current value of main in package.json makes sense at all:

xregexp/package.json

Line 18 in a661cd3

"main": "./lib",

Is ./lib loadable?

The same for React-Native

It appears that v2.0.0 is the last version that works with Browserify.

Thank you for reporting. Happy to accept pull requests that address this.

the problem is not that the pluggin is not imported?

the right is ?
import addons/unicode/unicode-base ?

[webmobiles]

not really needed 'import unicode-base' on my react app,
it's working ok, here my code:

import XRegExp from 'xregexp';
export const alpha = (value) => {
  const unicodeWord = XRegExp('^\\p{L}+$');
  return (!unicodeWord.test (value) ? 'validator.alpha' : '');
};

I was able to reproduce this as follows:

cd $(mktemp -d)
yarn add xregexp browserify
yarn browserify node_modules/xregexp

@knu:

Note that in v3.2.0, main points to xregexp-all.js, as indicated by @cainvommars (you can see the file on unpkg). It was changed to ./lib as part of #182. I believe this fixed the issue, as the following currently works on the master branch:

yarn # to build the files in ./lib
yarn browserify .

I'm hoping to release a new version to address this: #205
