我在笔记本电脑上尝试在 PyCharm 中重新安装 ultralytics 库时遇到问题。尽管没有对我的系统配置进行任何更改，但安装过程现在失败，并出现与 GCC 编译器相关的错误。
这令人费解，因为我之前已经成功安装了ultralytics，没有遇到任何问题。该错误消息表明 GCC 安装或其配置可能存在问题，即使我没有修改任何相关内容。
我需要进一步调查以确定错误的确切原因并找到解决方案。这可能涉及检查 GCC 安装是否存在任何不一致、验证其在环境变量中的路径，或确保 PyCharm 的 Python 解释器配置正确。错误图片

明显的错误是 gcc 版本太低，但是当在 Windows 机器上从源代码编译 numpy 时，已经出现了“错误”。这意味着您使用的 python 版本（看起来像 3.13）与您需要的 numpy 版本不兼容 (
numpy\<2.0.0,\>=1.23.0我猜你已经在新设置中切换到了新的 python 版本，也许是因为你有多个并且你的新 Pycharm 选择了 3.13，而你的旧版本被配置为使用另一个版本。
检查您的设置并配置不同的 python 版本 <3.13 in your project settings. Then attempt to install again
