Lesscss command line compiler Lessc

问题

Hi Im trying to get the LessCss command line compiler installed on a Mac.

I've tried

brew install less
Error: No available formula for less

brew install lessc
Error: No available formula for lessc

sudo npm install -g less
..Installs happily..

sudo npm install -g lessc
npm http GET https://registry.npmjs.org/lessc
npm http 404 https://registry.npmjs.org/lessc
npm ERR! 404 'lessc' is not in the npm registry.

npm install less --global
..Installs happily..

npm install lessc --global
npm http GET https://registry.npmjs.org/lessc
npm http 404 https://registry.npmjs.org/lessc
npm ERR! 404 'lessc' is not in the npm registry.

and all I get is

less js/less/style.less > style-theme.css
-bash: less: command not found

lessc js/less/style.less > style-theme.css
-bash: lessc: command not found

Does anyone have any experience with this?

I found something said my path variable might be messed up. This:

/bin/echo $PATH

gets me:

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin

回答1:

the npm package name for lessc is less

try writing

sudo npm install -g less

I will try to provide a complete answer.

All commands must be executed in the Terminal application.

1. If you don't have it: Install Command Line Tools for Xcode

   xcode-select --install

2. If you don't have it: Install HomeBrew

   ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

3. If you don't have it: Install Node.js

   brew install node

4. Install LessCSS

   sudo npm install -g less

Now you can execute lessc commands.

i`m using macOS Siera and work for me, you can try:

1. install npm using brew:

   brew install node

2. check node and npm version using:

   node -v npm -v

3.change user to SU using:

sudo su

4. install less:

npm install -g less

Good Luck.....
