无法在 Python 3.8.8 上安装 PyCurl 7.43.0.6

如何解决无法在 Python 3.8.8 上安装 PyCurl 7.43.0.6 | RHEL 8.3

工作站详细信息：

RHEL 8.3 - x86_64
Python 3.8.8
libcurl 7.61.1-14.el8_3.1

我试过了

pip install pycurl==7.43.0.6

错误[回溯]：

请帮忙。

解决方法

错误来源与Python或pycurl包无关。这是由于 RHEL 上缺少 libcurl-devel。

错误信息/引用没有明确提到这一点。

在 RHEL 8 中，我使用 sudo dnf install libcurl-devel 安装了该库。

后来，pip install pycurl==7.43.0.6 解决了这个问题。
