在 RHEL 的虚拟环境中安装 psycopg2 失败
Installing psycopg2 in virtual env on RHEL fails
我已经研究这个好几天了。每次我尝试将 psycopg2 安装到我的 RHEL VPS 上的虚拟环境中时，它都会失败并出现以下错误。任何有线索的人都应该帮忙。谢谢

我找到了解决方法。我注意到它在全球范围内成功安装。所以我全局安装了 psycopg2 并使用 --system-site-packages 选项创建了一个新的虚拟环境。然后我使用 -I 选项安装了我的其他包。
希望这对其他人有帮助。
好的。后来我发现我没有安装 gcc 。所以我必须先安装它。在那之后，我可以 pip install psycopg2。谢谢cel指点。
对我来说，我使用的是 Redhat 8 企业版，我的问题并没有通过安装 gcc 和 gcc-c++ 得到解决。
我通过安装 python3-devel 和 development tools.
解决了这个问题
要使用 yum 管理器在 Redhat 上安装它们，请按照此操作 link
