python离线安装第三方库
1、场景介绍
在一些服务器上，我们搭建完Python环境之后，因为服务器的网络限制原因，不能直接通过pip命令下载安装Python的依赖包。
因此，我们需要在可以正常上网的服务器上下载好所需的依赖包文件，然后拷贝到目标服务器，通过pip在目标服务器上进行安装。
2、准备requirements.txt文件
requirements.txt文件罗列的是依赖包列表，表示你要下载的依赖包以及对应的版本。
该文件可以通过两种方式创建，分别是pip命令创建和手工创建。
jupyter==1.0.0
notebook==6.1.0
- 1
- 2
（1）pip命令创建requirements.txt，可以把当前服务器的Python依赖包生成列表到requirements.txt文件中。
【pip list】
【pip freeze >requirements.txt】
（2）手工创建
requirements.txt，直接新建一个requirements.txt文件，然后按照格式填写所需依赖包以及对应版本号。
3、下载依赖包
注意：该步骤需要在可以正常上网的服务器上下载。下载的依赖包文件如图2所示。
pip download -r requirements.txt -d packages/ -i https://pypi.tuna.tsinghua.edu.cn/simple
- 1
其中：（packages/是要生成的文件夹，存放下载的依赖包文件；https://pypi.tuna.tsinghua.edu.cn/simple是镜像源地址）。
4、安装依赖包
准备好依赖包之后，就可以在无法使用pip命令下载安装依赖包的目标服务器上进行安装了。
使用命令之前，需要把packsges文件夹、requirements.txt文件拷贝到目标服务器，下面以requests依赖包为例。
pip install --no-index --find-links=./packages -r ./requirements.txt
- 1
（其中：./packsges是依赖包的所在路径；./requirements.txt是依赖包的列表路径）。
D:\zjj\pip>pip list
