不能加载匀称的包

Question

我需要下载shapely，但我总是出错。

起初，我尝试使用：

pip install shapely

它不起作用，所以我在网上搜索它，有人告诉我去这里下载文件：https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely我下载了名为Shapely1.6.4.post1-cp37-cp37mwin_amd64.whl的文件，因为我的窗口是64位，这是最新的一个。我又试了一次，但没有成功。我在这个问题（https://gis.stackexchange.com/questions/62925/why-is-shapely-not-installing-correctly）中发现的告诉我试试这个：

pip install Shapely-1.6.4.post1-cp37-cp37m-win_amd64

它也不起作用，但是错误消息是不同的。

以下是我收到的错误消息：

我还有geos模块，因为在PyPI页面中，我说您需要它来进行shapely安装。

Answer 1

确保你下载了适用于你的Python版本的轮子，cp37不能在3.7以外的任何其他Python版本上工作。也找到安装Python的地方，导航到venv-

Answer 2

确保指定控制盘文件的完整路径Shapely-1.6。4.post1-cp37-cp37m-win_amd64。whl，然后重试。
