pip安装后，virutalenv中的Python 3缺少包文件夹

我的软件包使用main.py作为cli，因为我经常使用代码。
我希望它在有cli位的地方工作，例如，
执行以下操作：iospytools——下载xy，这是唯一的部分
目前有效的软件包的一部分。它只给了我cli，
而且我的其余代码也不能用于其他项目，我可以
导入，因为我还将代码上传到了pypi.org

My 1.0.3 setup.py：

我使用的命令：

“python3-m-venv-venv”
“.venv/bin/activate”
“pip安装。”

你也可以跟着我做这件事，因为我在pypi上有我的代码。 可以通过“pip安装iospytools==1.0.3”进行安装

使用旧版本时，我的文件夹“iospytools”包含我的其他模块，
它实际上被复制到了venv/lib/python3.8/site-packages/文件夹中，如下所示

% ls -l venv/lib/python3.8/site-packages/iospytools

现在，如果我们只安装我的最新版本“1.0.6”atm，我们会得到不同的输出

% ls -l venv/lib/python3.8/site-packages/iospytools                                                                                                                         
ls: cannot access 'venv/lib/python3.8/site-packages/iospytools': No such file or directory

我已经检查了这些差异，这是它们之间唯一的差异：

> REQUIREMENTS = [i.strip() for i in open("requirements.txt").readlines()]
> # rbp https://stackoverflow.com/questions/6947988/when-to-use-pip-requirements-file-versus-install-requires-in-setup-py
> 
8c11
<     version="1.0.3",
---
>     version="1.0.6",
29a33
>     install_requires=REQUIREMENTS

>REQUIREMENTS=[i.strip（）用于打开的i（“REQUIREMENTS.txt”）.readlines（）]
>#限制性商业惯例https://stackoverflow.com/questions/6947988/when-to-use-pip-requirements-file-versus-install-requires-in-setup-py
> 
8c11
version=“1.0.6”，
29a33
>安装要求=要求

我很困惑，因为唯一的区别（除了版本）是我实际上添加了依赖项。我应该换一种方式吗
