ruby on rails - sitepoint - ExecJS:: RuntimeError: SyntaxError: Token inesperado: operator(>)(línea: 22342, col: 24, pos: 826182)

sitepoint react rails

Question

Desarrollador de raíles bastante nuevo aquí. Me estoy encontrando con este mensaje de error al intentar implementar de manera efectiva mi aplicación de rieles en Heroku. Supongo que se está ejecutando algún error sintáctico cuando los activos JS precompilan.

Encontré un problema similar aquí en SO, pero parece que todavía no se ha resuelto y he intentado todas las sugerencias en las respuestas.

Cualquier ayuda es apreciada. Aquí está el rastro de línea de comando de mi problema:

ExecJS::RuntimeError: SyntaxError: Unexpected token: operator (>) (line: 22342, col: 24, pos: 826182)

Answer 1

Tuve el mismo problema, y ​​resultó que estaba usando una función de flecha ES6. El problema era que la versión de Sprockets que estaba usando mi entorno de producción aún no era compatible con ES6.

Mi solución en ese momento era eliminar la función de flecha. La alternativa es usar algo como sprockets-es6 o una de las versiones beta de piñones .
