我修改了一个项目，将文本插入图像中。它在本地服务器上完美运行，但在远程服务器上他说：在此服务器上找不到请求的 URL/covers/03c7c0ace395d80182db07ae2c30f034.jpg。
该脚本不会创建映像，但在我的本地服务器上它可以工作。GD和Freefont已安装，所以我不知道该怎么办请帮助我

</html>您是否检查过封面目录的权限？将其设置为 644 或 777。
我假设您正在Windows本地运行该项目。Windows 处理权限的方式与 Linux 不同。这就是为什么它在本地工作，但不在您的远程服务器上工作。
他打败了我，但是：
chmod("/file/or/directory", 0777);
我忘了：如果您(您的网络服务器(对该目录没有写入权限。你不能直接chmod那个目录，你需要从shell中获取Chown或chmod的所有权。
在 Linux 终端中
sudo chmod 777 /some/directory
