用pip整齐安装

Question

我刚刚用以下命令在我的项目中创建了我的虚拟环境:python -m virtualenv venv', and I activated it. I tried to install files from the requirements.txt file with the commandpip install -r requirements.txt'。我在这两种情况下都尝试了venv on或of。在需求文件中有一些普通包和一些私有包。当安装最后一个私有包时，出现以下错误:

Collecting Shapely==1.7.1

所以在形状安装时出现错误。阅读所有的requirements.txt文件，没有一个人在里面有shape。但也许其他软件包也需要它。我读了很多StackOverflow的答案，人们告诉我使用conda而不是pip，但我不能，因为我需要在这个虚拟环境中工作

如何解决这个问题?如果你可以,请帮助我。

Answer 1

我在Ubuntu上遇到了同样的问题，这个问题通过运行命令来解决:

sudo apt-get install libgeos-c1v5

Answer 2

尝试从这里下载geos_c.dll文件:https://www.dll-files.com/geos_c.dll.html，然后在您的pc系统目录中解压缩zip文件(例如C:WindowsSystem32 for windows from XP on)。然后将system目录添加到路径中，并按形状安装1.6.3。
