I'm hoping to find an easy solution to this problem.
I want to install the American Economic Association document class and use it in Lyx. I have inserted the class file into the right latex directory and run texhash. Next I created a simple layout file, played it in the layout folder, and reconfigured Lyx. Now, American Economic Association (AEA) appears in my dropdown menu as a document class option in class under the articles heading, but when I try to use the file, it tells me that there is a problem with the layout file.
I suspect that I have no found the correct layout folder. The layout folder I'm using is empty except for the file I added. Is this normal? I can't find, for example, the article.layout file. I should say that Lyx appears to be working normally otherwise. I have no problem compiling normal files.
I'm on a Macbook Pro running OSX Yosemite. The directory I have been using for layout files is /Users/amandaggregg/Library/Application Support/LyX-2.1/layouts, which Lyx preferences indicate should be the right folder.
I know about http://www.troubleshooters.com/linux/lyx/surefire_layout.htm, but it looks complicated and time-consuming. Hoping to find an easier solution.
Looking forward to your responses
