我尝试使用源文件手动安装它，但它也给出了以下错误

>>> pip install proj-7.1.1.tar.gz

如何解决这个错误？ (非conda环境必须安装)

Answer 1

PROJ 是一个 C 库，不是 Python 包，因此您不能使用 pip 安装它。

如果您只想使用来自 Python 的 PROJ，您可以使用 PyPROJ 并使用 pip install pyproj 安装它。在 MacOS、Linux 和 Windows 上，这将为您提供已经包含 PROJ 的预制轮子。

如果您尝试为 CartoPy 安装它（基于您的标签），您需要在 their install instructions.

之后单独安装 PROJ
