less css and node js troubles

Question

When I try to install less css compiler under my Ubuntu 13.10 box I get following message and lescss don't working. In what way I can fix the problem? I execute:

sudo npm install -g less

After this I get e list with OK messages:

npm http 304 https://registry.npmjs.org/cryptiles
npm http 304 https://registry.npmjs.org/ctype/0.5.2
npm http 304 https://registry.npmjs.org/combined-stream
npm http GET https://registry.npmjs.org/delayed-stream/0.0.5
npm http 304 https://registry.npmjs.org/sntp
npm http 304 https://registry.npmjs.org/boom
npm http 304 https://registry.npmjs.org/delayed-stream/0.0.5

And list finished with following:

 /usr/local/bin/lessc -> /usr/local/lib/node_modules/less/bin/lessc
    [email protected] /usr/local/lib/node_modules/less
    ├── [email protected]

After this when I tried the following commands:

echo "@foo: 25px; #foobar{font-size: @foo};" > style.less
sudo lessc ./style.less ./style.css

I get the following error:

/usr/bin/env: node: No such file or directory

After I executed

ln -s /usr/bin/node /usr/local/bin/nodejs

and created symlinks there is no errors but lessc compiler don't working properly. I have created file to test. It content is:

cat style.less

@color: #4D926F;

#header {
  color: @color;
}
h2 {
  color: @color;
}`

and after trying

lessc styles.less > styles.css

There is created file - styles.css but the file is empty. I also try commands that I tryed before - see top on the post.

lessc styles.less styles.css

But it not working. There is no file as a result. When I tried

sudo npm install -g less

In the last line I receive following error.

npm http 200 https://registry.npmjs.org/delayed-stream/-/delayed-stream-0.0.5.tgz
/usr/bin/lessc -> /usr/lib/node_modules/less/bin/lessc

Move it away, and try again.

Those exact commands worked for me pasted into my node server. Running ubuntu 12.04 with node installed. Can you run node from where you are (is it in your PATH)? — Aboba

When you type env node --version does it tell you your node version or does it tell you "No such file or directory"? And, what is the output of which env? What distro of Linux are you using? — Evan Carroll

The > command operator is incorrect in your command. The correct command is :

lessc [sourcefile] [destfile]

For your example, your command is :

lessc styles.less styles.css
