从 Github 导入 Python 库

Import a Python library from Github

提问by Nyxynyx

I'm new to Python so this may sound silly.

我是 Python 新手，所以这听起来很傻。

I want to use a Python library I've found on Github, lets say on https://github.com/praw-dev/praw, and I want to be able to do git pullin the future to pull the latest commits.

我想使用我在 Github 上找到的 Python 库，比如说 on https://github.com/praw-dev/praw，我希望git pull将来能够提取最新的提交。

Question:Should I git clone <git url>in the project directory and delete everything except the prawdirectory, then in my python script do a import praw?

问题：我应该git clone <git url>在项目目录中删除除praw目录之外的所有内容，然后在我的 python 脚本中执行import praw?

In iPython,

在 iPython 中，

import praw

gives the error ImportError: No module named praw

给出错误 ImportError: No module named praw

You might want to consider using pipinstead of git to install and upgrade the package (that is unless you have a pressing reason to use git).

您可能要考虑使用pip代替 git 来安装和升级包（除非您有使用 git 的紧迫理由）。

pip install praw

pip install praw

to update the package you can do

更新你可以做的包

pip install --upgrade praw

pip install --upgrade praw

Also have a look herefor further information on how to use pip.

Just clone the files in any dir on your python path and then build the lib typically with python setup.py installfrom the command line.

只需克隆 python 路径上任何目录中的文件，然后通常python setup.py install从命令行构建 lib 。

I typically clone a libray form git in my site_librariesfolder ( the folder that holds all of your pip installed packages ). From there you can pull and then build the libraries from git just like any other git repo. Having the files there is nice because all of your libs are in once place on your python path.

我通常在我的site_libraries文件夹（包含所有 pip 安装包的文件夹）中克隆一个库形式 git 。从那里你可以像任何其他 git repo 一样从 git 拉取然后构建库。将文件放在那里很好，因为您的所有库都在您的 python 路径上。

Actually, if given package is not on PyPI (or you want a specific branch) you can still install it through pip from GitHub with:

实际上，如果给定的包不在 PyPI 上（或者你想要一个特定的分支），你仍然可以通过 GitHub 上的 pip 安装它：

pip install git+https://github.com/[repo owner]/[repo]@[branch name]

And for your problem it would be (although @pandita's answer is correct for normal usage case):

对于您的问题，它将是（尽管@pandita 的答案对于正常使用情况是正确的）：

pip install git+https://github.com/praw-dev/praw.git

Experimental Python module finder/loader from github, like in golang.

来自 github 的实验性 Python 模块查找器/加载器，就像在 golang 中一样。

So, in golang we can import like:

所以，在 golang 中，我们可以像这样导入：

import "github.com/parnurzeal/gorequest"

But in python we should install package by our hands:

但是在python中，我们应该手动安装包：

pip install requests

And import it like:

并像这样导入：

import requests

But with this magic package and power of PEP-0302 we can do it automatically:

但是有了这个神奇的包和 PEP-0302 的强大功能，我们可以自动完成：

from github_com.kennethreitz import requests

assert requests.get('https://github.com/nvbn/import_from_github_com').status_code == 200

Installation

安装

You should have git, Python 3.2+ and pip:

你应该有 git、Python 3.2+ 和 pip：

pip install import_from_github_com
