OpenGL着色器编译错误(C0000和C0206) (PyOpenGL)

I'm still pretty new to opengl and i'm trying to compile my vertex and fragment shader but keep getting an error. Heres the shaders i'm compiling:

我对opengl还是很陌生的，我正在尝试编译我的顶点和片段着色器，但不断出错。我正在编译的着色器:

# Vertex shader
vert_shader = """
#version 330
in vec4 position
void main()
{
    gl_Position = vec4(position, 1.0f);
}

"""

# Fragment shader
frag_shader = """
#version 330
void main()
{
    gl_FragColor = vec4(1.0f, 0.0f, 0.0f, 1.0f);
}

"""

# Compiles the vertex and fragment shader
shader = OpenGL.GL.shaders.compileProgram(OpenGL.GL.shaders.compileShader(str(vert_shader), GL_VERTEX_SHADER),
                                          OpenGL.GL.shaders.compileShader(str(frag_shader), GL_FRAGMENT_SHADER))

When i run my program, i get this error:

当我运行程序时，我得到这个错误:

RuntimeError: ('Shader compile failure (0): b\'0(4) : error C0000: syntax error, unexpected reserved word "void", expecting \\\',\\\' or \\\';\\\' at token "void"\\n\'', [b'\n    #version 330\n    in vec4 position\n    void main()\n    {\n        gl_Position = vec4(position, 1.0f);\n    }\n\n    '], GL_VERTEX_SHADER)

Initially i thought i was getting this error because i didn't parse the string and take out the new line indicators, but once i took those out using the 'replace' string function, i got this error:

最初，我以为我得到了这个错误，因为我没有解析字符串并取出新的行指示器，但是一旦我用“替换”字符串函数取出这些，我就得到了这个错误:

RuntimeError: ('Shader compile failure (0): b\'0(1) : error C0205: invalid profile "in"\\n0(1) : error C0206: invalid token "vec4" in version line\\n\'', [b'    #version 330    in vec4 position    void main()    {        gl_Position = vec4(position, 1.0f);    }    '], GL_VERTEX_SHADER)

I even tried encoding the string as ascii after parsing it but that didn't seem to work either.

我甚至尝试在解析后将字符串编码为ascii，但这似乎也不起作用。

Your vertex shader had syntax errors, try again with this fixed one:

你的顶点着色器有语法错误，再试试这个固定的:

#version 330

in vec4 position;

void main()
{
    gl_Position = position;
}

1) You were missing ';' in the line in vec4 position

你失踪了，在vec4的位置。

2) Line gl_Position = vec4(position, 1.0f); was trying to create a vec4 instance with the first argument position, which happens to be a vec4. To fix it you can just assigning directly the vec4 position like gl_Position = position; or using swizzling like gl_Position = vec4(position.xyz, 1.0);

2)Line gl_Position = vec4(位置，1.0f);尝试用第一个参数位置创建一个vec4实例，它恰好是一个vec4。要修复它，您可以直接指定vec4位置，比如gl_Position =位置;或者使用像gl_Position = vec4(位置)这样的旋转。xyz,1.0);
