#### 1.安装 ####

**前提是已经安装了Anaconda**[Scrapy第二(①)篇python环境之依赖管理器Anaconda(python3.9)\_苍穹之跃的博客-CSDN博客![icon-default.png?t=M7J4][icon-default.png_t_M7J4]https://blog.csdn.net/wenxingchen/article/details/126438532][Scrapy_python_Anaconda_python3.9_-CSDN_icon-default.png_t_M7J4_icon-default.png_t_M7J4_https_blog.csdn.net_wenxingchen_article_details_126438532]

执行安装命令：

conda install -c conda-forge scrapy

提示安装失败

修改镜像源：cmd执行以下两条命令

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

conda config --set show_channel_urls yes

此时在地址C:\\Users\\电脑用户名；下就会生成配置文件.condarc

修改这个文件为：**（注意：修改的镜像源的协议是http，不是https）**

channels:
      - defaults
    show_channel_urls: true
    default_channels:
      - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
      - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
      - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
    custom_channels:
      conda-forge: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
      msys2: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
      bioconda: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
      menpo: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
      pytorch: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
      simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
