我在安装xfoil python包时遇到了问题收集xfoil使用缓存xfoil-1.1.1.tar.gz (12 kB)准备元数据(setup.py)…完成要求已经满足:numpy在c:usersxxxdesktopcurvevenvlibsite-packages (from xfoil) (1.22.4)为收集的包裹建造轮子:xfoil为xfoil构建轮子(setup.py)…错误错误:subprocess-exited-with-error

我该怎么处理呢?非常感谢
问题似乎是构建过程失败了，因为pip试图编译源代码，但它失败了，因为这个过程的先决条件不存在。
要使此工作，您可以使用预编译(构建)包安装包。该包只发布了Python 3.7的构建包https://pypi.org/project/xfoil/文件
要使用此功能，请创建一个使用Python 3.7版本的Python虚拟环境。
我使用如下Anaconda Python发行版实现了这个工作。
首先，使用Python 3.7
创建一个虚拟环境conda create -n xfoil python=3.7
pip install xfoil
由于此环境使用的是Python 3.7版本，因此将下载构建的xfoil发行版(wheel文件.whl)。控制台输出如下所示:
Collecting xfoil
Downloading xfoil-1.1.1-cp37-cp37m-win_amd64.whl (442 kB)
|████████████████████████████████| 442 kB 1.6 MB/s
Requirement already satisfied: numpy in c:usersjoeminiconda3envsxfoillibsite-packages (from xfoil) (1.19.5)
Installing collected packages: xfoil
Successfully installed xfoil-1.1.1
如果您想使用最新的Python版本(您使用的是3.10版本)构建xfoil，请按照xfoil页面https://pypi.org/project/xfoil/上的"构建和安装Python模块">
下的构建说明进行构建。我也遇到过同样的问题，但是通过阅读Joe链接的页面(https://pypi.org/project/xfoil/)很容易解决这个问题。只需从Pypi镜像中下载文件，在目录
中解压缩并使用pip安装。pip install .
我的问题很可能与我的python版本有关…谢谢!
