如何修复通过 pip install 安装 pystan 时弹出的这个错误？

Question

这是我在 Windows 命令提示符中输入的内容：

C:\Users\jeane\Desktop\ethan\stan> pip install pystan

这是我的输出：

其实你可以尝试安装Anaconda。在谷歌搜索“Anaconda”，下载并安装它。然后，在你的Windows系统中搜索“Anaconda Prompt”并使用以下命令安装pystan：conda install pystan -c conda-forge之后，你应该看到这个：Solving environment: done## Package Plan ##&nbsp; environment location: C:\Users\User\Anaconda3&nbsp; added / updated specs:&nbsp; &nbsp; - pystanThe following packages will be downloaded:&nbsp; &nbsp; package&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; |&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; build&nbsp; &nbsp; ---------------------------|-----------------&nbsp; &nbsp; pystan-2.17.1.0&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; |&nbsp; &nbsp;py37h830ac7b_2&nbsp; &nbsp; &nbsp; &nbsp; 14.3 MB&nbsp; conda-forge&nbsp; &nbsp; openssl-1.0.2p&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;|&nbsp; &nbsp; &nbsp; &nbsp;hfa6e2cd_0&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;5.4 MB&nbsp; conda-forge&nbsp; &nbsp; conda-4.5.11&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;|&nbsp; &nbsp; &nbsp; &nbsp; py37_1000&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;654 KB&nbsp; conda-forge&nbsp; &nbsp; ------------------------------------------------------------&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Total:&nbsp; &nbsp; &nbsp; &nbsp; 20.3 MBThe following NEW packages will be INSTALLED:&nbsp; &nbsp; pystan:&nbsp; 2.17.1.0-py37h830ac7b_2 conda-forgeThe following packages will be UPDATED:&nbsp; &nbsp; conda:&nbsp; &nbsp;4.5.11-py37_0&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;--> 4.5.11-py37_1000&nbsp; conda-forge&nbsp; &nbsp; openssl: 1.0.2p-hfa6e2cd_0&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;--> 1.0.2p-hfa6e2cd_0 conda-forgeProceed ([y]/n)?只需按 y。Anaconda 将自动下载并安装它。

您是否尝试在那里安装它所说的内容？pip&nbsp;install&nbsp;Cython应该管用
