通过pip将软件包安装到单独的目录

Question

我正在尝试将一个依赖包安装到现有项目中的一个单独目录中，如下所示：

python -m pip install -t C:\Users\Mahdi\eclipse-workspace\
google-cloud-functions\com\mahdi\python\functions\gcs\dependency com.mahdi.python.file_igestion

但是我得到了下面的错误。我是不是遗漏了什么？

Could not find a version that satisfies the requirement com.mahdi.pyhton.file_igestion (from versions: )
No matching distribution found for com.mahdi.pyhton.file_igestion

编辑:根据建议，我可以通过setup.py sdidst安装软件包，我可以看到已安装的软件包

C:\Users\Mahdi\eclipse-workspace\google-cloud-functions>python -m pip list
Package                  Version    Location
------------------------ ---------- -------------------------------------------------------
file-ingestion           0.2        c:\users\mahdi\eclipse-workspace\google-cloud-functions

但是当我运行blow命令时，我仍然得到错误

C:\Users\Mahdi\eclipse-workspace\google-cloud-functions\com\mahdi\python\functions\gcs>python -m pip install -t C:\Users\Mahdi\ecli
pse-workspace\google-cloud-functions\com\mahdi\python\functions\gcs\dependency file-ingestion

You are using pip version 10.0.1, however version 18.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Answer 1

要安装在本地构建的包，您需要使用类似于

pip install mypackage --no-index --find-links file:///srv/pkg/mypackage

您需要先使用python setup.py sdist将其打包。
