自定义包安装失败

Question

我想让我的 Jupyter 笔记本导入自定义 Python 模块。 为此，我尝试安装一个可以导入其模块的包，例如，通过

from projectmnemonic import test

.

我的库的源代码目录结构如下：

my-datascience-project/
    ...
    notebooks/
    ...
    projectmnemonic/
        projectmnemonic/
            __init__.py
            test.py
        setup.py
    ...

setup.py

很平淡（无意发表）：

from setuptools import setup

setup(
    name="projectmnemonic",
    version="0.1", 
)

我在激活的anaconda环境下安装包如下

pip install -e path/to/my-datascience-project/projectmnemonic

但出现以下错误：

Defaulting to user installation because normal site-packages is not writeable

Obtaining <path to my-datascience-project/projectmnemonic>
  Preparing metadata (setup.py) ... done

        [end of output]

    note: This error originates from a subprocess, and is likely not a problem with pip.

当我将目录

projectmnemonic

移动到桌面并从那里安装时，我在安装过程中没有问题：

Defaulting to user installation because normal site-packages is not writeable
Looking in indexes: <redacted>
Obtaining <path to my-datascience-project/projectmnemonic>
  Preparing metadata (setup.py) ... done
Installing collected packages: <projectmnemonic>

Successfully installed <projectmnemonic>-0.1

Python 3.9.12，设置工具 67.6.1

Answer 1

可编辑安装

(-e flag)

和您的目录结构可能存在问题。

首先修改

setup.py

文件，加入

packages

参数

from setuptools import setup, find_packages

setup(
    name="projectmnemonic",
    version="0.1",
    packages=find_packages()
)

然后去projectmnemonic

cd path/to/my-datascience-project/projectmnemonic

然后正确安装你的包

pip install -e .
