尝试链接我的着色器时，我收到错误代码"error c5145 must write to gl_position"

我使用vs2019作为我的IDE，GLEW(版本2.1.0(、glm和GLfw(3.3.2(作为库。当尝试链接顶点着色器时，我得到了前面提到的错误代码。

ERROR::SHADER::Programm::LINK_ERROR
Vertex info
-----------
(0) : error C5145: must write to gl_Position

您可以在下面找到编译和链接着色器的代码。编译似乎没有任何问题，但链接不适用于顶点着色器，片段着色器似乎很好。

这是顶点着色器本身：

#version 330 core
layout (location = 0) in vec3 position;
layout (location = 1) in vec3 color;
layout (location = 2) in vec2 texCoord;

out vec3 ourColor;
out vec2 TexCoord;

void main()
{
gl_Position = vec4( position, 1.0f );
ourColor = color;
TexCoord = vec2( texCoord.x, 1.0 - texCoord.y);
}

非常感谢您的帮助。

编辑。这是有人要求的碎片着色器

#version 330 core
in vec3 ourColor;
in vec2 TexCoord;
out vec4 color;
uniform sampler2D ourTexture1;
void main()
{
color = texture (ourTexture1, TexCoord);
}

edit2.将分号添加到color = texture (ourTexture1, TexCoord);，并将TexCord添加回顶点着色器。问题仍然存在。
