Hmmm, I get this on my Mac as well.

[ralyodio]

I just did npm install unicode and that fixed the problem. I think something along the line is missing that as a dependency.

[parmentf]

After npm install unicode, the problem is still here (Ubuntu 14.04, node 4.2.2, npm 2.14.7). It's unicode@0.6.1.

I meet the same problem on Cent OS 7 / node 5.6.0 / npm 3.6.0

npm install unicode not work for me.

[rvanzon]

@haishanh run it in node_modules/slug. It's dirty, but it does the trick.

I'm getting this error too, on my Debian 8.2 box. Didn't get it when running locally on my Mac.
Using node v5.10.1 and npm 3.8.3.

Used npm install unicode as a workaround.

[simison]

Could this have something to do with this:

# debian
sudo apt-get install unicode-data # optional
# gentoo
sudo emerge unicode-data # optional

npm install unicode

If you have problems installing UnicodeData.txt because unicode.org is down or you're behind a proxy, try installing unicode-data via your system package installer.

https://www.npmjs.com/package/unicode#install

[1yx]

@parmentf
try download UnicodeData.txt somewhere else.
cd /tmp && wget http://unicode.org/Public/UNIDATA/UnicodeData.txt
export NODE_UNICODETABLE_UNICODEDATA_TXT=/tmp/UnicodeData.txt
then
npm install unicode gonna work well.

There is a pending PR which will resolve this - dodo/node-unicodetable#22

[rajendrakhabiyagate6]

If you are facing this issue and you are behind windows please follow below steps, i hope worked for you :

1. Remove the unicode module using npm, npm remove unicode
2. Downloaded the file from
   http://unicode.org/Public/UNIDATA/UnicodeData.txt and placed it into
   C:\usr\share\unicode-data\ if your project is in C drive, or if you are using
   linux place it in /usr/share/unicode or /usr/share/unicode-data
3. Installed unicode again

I'm still facing this issue while deploying my app to heroku. None of the above proposed quick fixes is working ... Any idea?

[dylanjha]

Running into this on circleci, I assume because circle installs from behind a proxy: https://discuss.circleci.com/t/node-cannot-find-module-unicode-category-so/8990

I tried the options from the install section https://github.com/dodo/node-unicodetable#install:

• (installed unicdoe-data successfully but didn't resolve the issue) sudo apt-get install unicode-data
• (succeeded but didn't resolve the issue) cd /tmp && wget http://unicode.org/Public/UNIDATA/UnicodeData.txt then export NODE_UNICODETABLE_UNICODEDATA_TXT=/tmp/UnicodeData.txt

Hoping this PR lands, which should resolve this issue entirely dodo/node-unicodetable#22

[dylanjha]

@antoinedejonckheere trying setting the env variable NODE_MODULES_CACHE=false in your Heroku environment, see if that works for you

[antoinedejonckheere]

@dylanjha amazing, it worked. My interpretation then is that for one deployment, the install was unsuccessful. Next installations were then using the cached version of the package (which was failing), correct?

[dylanjha]

@antoinedejonckheere I thought that at first too, but I don't think that is it. If you re-enable the cache it will fail again. To be honest, I don't have an explanation, maybe someone else can chime in if they know.

[dylanjha]

@antoinedejonckheere also, if converting unicode isn't important to you, check out this module, which doesn't rely on unicode (unicode characters get removed instead of converted) https://www.npmjs.com/package/slugs

[antoinedejonckheere]

@dylanjha thanks, moving to another package was indeed what I decided to do :) thanks again for your kind help
