二. win7离散安装

离线安装 playwright 环境

r"""  node.exe(低版本playwright windows7才支持) 浏览器(适用playwright版本) 
【0】F:\Program Files (x86)\jetbrains\python3.8.9>python -m pip install --upgrade pip
【1】win7需要安装低版本playwright  高版本出现如下错误：
Node.js is only supported on Windows 8.1, Windows Server 2012 R2, or higher

【2】不使用该方案的虚拟环境(venv) 直接使用已安装python3.8.9的解释器
1. F:\Program Files (x86)\jetbrains\python3.8.9\Scripts 该目录(简称D目录)下打开cmd
pip download playwright==1.15.3 -d f:/home/playwright1.15.3 (下载低版本 win7支持)
2.将f:/home/playwright1.15.3目录内文件复制到  D目录/home/playwright1.15.3
3.D目录/home/a1.txt  生成a1.txt内容如下：

greenlet==2.0.2
playwright==1.15.3
pyee==11.0.0
typing_extensions==4.8.0
websockets==11.0.3

4.安装低版本 卸载再重新安装
pip uninstall -y playwright (卸载)
pip install --no-index --find-links=.\home\playwright1.15 -r .\home\a1.txt (重新安装)

【3】安装成功后 查看如下目录 node.exe适用playwright的版本
F:\Program Files (x86)\jetbrains\python3.8.9\Lib\site-packages\playwright\driver\node.exe

【4】程序运行仍有可能出错 需要适用的浏览器
F:\Program Files (x86)\jetbrains\python3.8.9\Scripts  playwright install
F:\Program Files (x86)\jetbrains\python3.8.9>python -m playwright install (model同上)
playwright install (报错 显示谷歌版本 适合playwright-1.15.3版本的 默认安装多个浏览器)
C:\Users\Administrator\AppData\Local\ms-playwright(查看该目录 默认安装多个浏览器)
C:\Users\Administrator\AppData\Local\ms-playwright\chromium-920619 目录

【5】再卸载重新安装 只安装谷歌浏览器
C:\Users\Administrator\AppData\Local\ms-playwright (仅删除已安装浏览器目录)
F:\Program Files (x86)\jetbrains\python3.8.9\Scripts  playwright install chromium
C:\Users\Administrator\AppData\Local\ms-playwright\chromium-920619 (新增浏览器目录)

【6】如果报错DLL load failed while import _greenlet:找不到指定的模块
pip download msvc-runtime -d /home/msvc-runtime
