python断网环境 离线安装第三方包

作者:互联网

python断网环境 离线安装第三方包,主要依赖pip的相关用法

先看pip的相应参数,命令行执行pip -h,可以看到参数很多:

方法一.在另一台电脑逐一下载相关安装包,在断网主机上依次安装相应安装包

pip download -d F:\ZK\py\whl\py387 xlrd
pip download -d F:\ZK\py\whl\py387 -i https://pypi.doubanio.com/simple/ xlwt
pip download -d F:\ZK\py\whl\py387 -i https://pypi.doubanio.com/simple/ --only-binary=:all: --python-version 38 pandas
pip install --no-index --find-links=F:\ZK\py\whl\py387\ xlrd
pip install --no-index --find-links=F:\ZK\py\whl\py387\ xlwt
pip install --no-index --find-links=F:\ZK\py\whl\py387\ pandas
pip list

命令1:在默认https://pypi.org/simple位置下载xlrd库

命令2:在豆瓣下载xlwt库,速度更快

命令3:下载基于python3.8的pandas库

然后在离线主机上执行以下命令:

命令4-6:从存放了whl的文件夹中,安装相应库

命令7:查看当前安装的库

 

方法二.在已安装python库的电脑上生成库清单,批量下载库,在断网主机上安装相应备份

pip freeze > requirements.txt
pip download -d F:\ZK\py\whl\py387 -i https://pypi.doubanio.com/simple/ -r requirements.txt

然后在离线主机执行以下命令:

pip install --no-index --find-links=F:\ZK\py\whl\py387 -r requirement.txt

方法二,更方便!

 

最后附上pip参数:pip -h
