Python pip-从本地目录安装

我必须下载一个 git python repo 并安装，因为 pypi 版本没有更新。

通常我会这么做:

pip install mypackage
pip install mypackage[redis]

现在，我将回购文件复制到以下文件夹中:

选择/包装

因此，我如何安装以下内容，同时确保我使用的是本地版本，而不是 pypi 版本。

pip --flag /opt/mypackage install mypackage
pip --flag /opt/mypackage install mypackage[redis]

有很多可用的 pip 标志，但我不知道如何实现:

You were looking for help on installations with pip. You can find it with the following command:

pip install --help

Running pip install -e /path/to/package installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development. Only use the -e flag if you need to edit the package's source code.

Further information about local installs and the -e/--editable flag of pip and its caveats is available in the official pip "Local project installs" and setuptools "Development Mode (a.k.a. "Editable Installs)" documentation chapters. The latter also lists a range of limitations of editable installs.

All you need to do is run

pip install /opt/mypackage

and pip will search /opt/mypackage for a setup.py or pyproject.toml, build a wheel, then install it.

The problem with using the -e flag for pip install as suggested in the comments and this answer is that this requires that the original source directory stay in place for as long as you want to use the module. It's great if you're a developer working on the source, but if you're just trying to install a package, it's the wrong choice.

Alternatively, you don't even need to download the repo from Github first. pip supports installing directly from VCS (version control systems) repos like git using a variety of protocols including HTTP, HTTPS, and SSH, among others. See the docs for examples.

To see all of the pip install command options, run

pip install --help

This command helped me.

pip install path/to/dir --use-feature=in-tree-build
