Question

在代码中实现ruby2d时出现此错误

这是一个奇怪的运行时问题

Ruby2d代码

require 'ruby2d'
# Set the window size
set width: 300, height: 200
# Create a new shape
s = Square.new
# Give it some color
s.color = 'red'
# Show the window
 show

错误

，请帮助我修复

Answer 1

您必须从MINGW 64位命令提示符下运行项目。不是从常规的DOS提示符(Windows命令提示符)。

确保遵循以下说明:

注意最后一段:

Using Ruby 2D on Windows

When working with Ruby 2D, make sure to use a MinGW 64-bit command prompt, rather than a standard one (cmd.exe) or the “Start Command Prompt with Ruby” found in the Start menu.
