Question

当我执行pip install statsmodels时，它会给我ImportError: statsmodels requires patsy. http://patsy.readthedocs.org，但之后我会运行pip install patsy并表示它已成功，但正在运行pip install statsmodels仍然会给我同样的错误

这怎么可能？

$ sudo pip install patsy
Requirement already satisfied (use --upgrade to upgrade): patsy in /Library/Python/2.7/site-packages/patsy-0.3.0-py2.7.egg
Requirement already satisfied (use --upgrade to upgrade): numpy in /Library/Python/2.7/site-packages/numpy-1.8.2-py2.7-macosx-10.9-intel.egg (from patsy)

Answer 1

错误消息没有告诉您的是six模块不在那里确实存在问题。

通过import patsy找到这个并让它失败并告诉我我需要six。所以我做了pip install six，现在patsy导入工作了，pip install statsmodels也是如此。

Answer 2

对我来说：

$python3 -m pip install --upgrade patsy
$python3 -m pip install statsmodels

工作！

Answer 3

对于任何仍有问题的人，我强烈推荐此网站： Python libraries。我正在使用Python 3，所以我，

下载名为statsmodels‑0.8.0‑cp35‑cp35m‑win_amd64.whl
打开Windows命令提示符
访问我的下载目录（cd Downloads）
然后使用pip（pip install statsmodels‑0.8.0‑cp35‑cp35m‑win_amd64.whl）

Answer 4

我在Python 3.4中也遇到过这个问题。它使用此链接上的WHL statsmodel文件：https://pypi.python.org/pypi/statsmodels#downloads

下载后我使用：pip3.4安装my_directory \ statsmodels-0.8.0rc1-cp34-none-win_amd64.whl，其中my_directory是我放置WHL文件的位置。

安装patsy，仍然无法安装statsmodels
