安装pyjags的又一次失败

Question

请帮助我在Anaconda windows环境中安装pyjags。pip和easy_install都会给出如下错误消息：

>pip install pyjags

我期待你的帮助

Answer 1

错误很明显：

Package jags was not found

快速查看一下pypi project page会发现同样的情况：

PyJAGS provides a Python interface to JAGS

所以pyjags只是jags的接口。为了使用这个接口（并且首先安装它），您需要有jags。官方上，有可用的windows文件from here，但是pyjags官方上只支持POSIX操作系统（也请参见pypi project page），因此即使您设法让JAG在您的操作系统上工作，也不能保证它是可安装的
