Issue arises when attempting to compile .less file with variables sourced from a separate file

I encountered an issue with my .less file where it contains definitions that rely on variables from another file.

For example:

body {
    font-family: @baseFontFamily;
    font-size: @baseFontSize;
    color: @textColor;
}

At first, IntelliJ displayed the variables as undefined. Upon compiling with Lessc, I came across the following error message:

TypeError: Cannot call method 'charAt' of undefined at getLocation (C:\PATH\npm\node_modules\less\lib\less\parser.js:212:34) at new LessError (C:\PATH\npm\node_modules\less\lib\less\parser.js:221:19) at Object.toCSS (C:\PATH\npm\node_modules\less\lib\less\parser.js:385:31) at C:\PATH\npm\node_modules\less\bin\lessc:107:28 at C:\PATH\npm\node_modules\less\lib\less\parser.js:434:40 at C:\PATH\npm\node_modules\less\lib\less\parser.js:94:48 at C:\PATH\npm\node_modules\less\lib\less\index.js:116:17 at C:\PATH\npm\node_modules\less\lib\less\parser.js:434:40 at C:\PATH\npm\node_modules\less\lib\less\parser.js:94:48 at C:\PATH\npm\node_modules\less\lib\less\index.js:116:17

Upon researching, I concluded that there was an error within my code. My initial assumption was that the issue stemmed from the variable definition not functioning correctly. When commenting out the lines containing variables, lessc compiled the project without any problems.

However, even after adding the necessary @import statement to define the variables (and uncommenting the variable lines), I still encountered the compile-time error. Is there something crucial that I am overlooking?

Answer №1

Discovered an issue where both the parent and child folders had a 'config.less' file. By transferring the contents of the config.less from the child to the parent version, I successfully resolved the issues I was facing.

Answer №2

After some investigation, I came across the solution. Instead of compiling all the .less files in the suite, I decided to compile just one file at a time. This approach revealed that NPM was struggling to find one of the Mixins being used. By properly @import-ing the necessary file, the entire suite now compiles without any issues.

The valuable lesson from this experience is: - When facing issues with a specific .less file, try compiling it independently. This way, NPM will provide more detailed information about the error instead of just a generic stack trace.

Answer №3

Encountering similar errors is something I've experienced while operating in this manner, but surprisingly the compiled css functions perfectly fine. My practice involves compiling less during development and solely incorporating the css at runtime to avoid any dependencies on javascript impacting styles...
