1. 关键点分析：
   - 从报错信息“Collecting DataAnalysisToolkit==1.2.2 Using cached dataanalysistoolkit - 1.2.2 - py3 - non”来看，似乎是在收集DataAnalysisToolkit包的过程中遇到了问题。很可能是网络连接问题导致无法正常从PyPI（Python Package Index）获取该包，或者该包本身存在一些与PyPI交互的兼容性问题。
2. 解决方案：
   - 检查网络连接：
   • 确保你的PyCharm所在的机器能够正常访问外网。可以尝试在浏览器中访问一些常用网站，如百度、谷歌等，检查网络是否畅通。
   • 如果网络有代理设置，需要在PyCharm中正确配置代理。在PyCharm的设置中找到“HTTP Proxy”选项，根据实际情况填写代理服务器地址和端口等信息。
   • 尝试更换镜像源：
   • 很多时候，默认的PyPI源可能因为网络或其他原因访问不稳定。可以使用国内的镜像源，如清华大学的镜像源。
   • 在项目的requirements.txt文件中（如果有的话），将DataAnalysisToolkit的安装行修改为：
     DataAnalysisToolkit==1.2.2 -i https://pypi.tuna.tsinghua.edu.cn/simple
   • 或者在安装命令中指定镜像源：
     pip install DataAnalysisToolkit==1.2.2 -i https://pypi.tuna.tsinghua.edu.cn/simple
   • 检查包的可用性：
   • 确认DataAnalysisToolkit包在PyPI上是否真的存在并且可用。可以通过访问PyPI官方网站来查看该包的详细信息。如果该包存在问题或已被移除等，可能会导致安装失败。
3. 各种方案的优缺点：
   - 检查网络连接：
   • 优点：简单直接，如果是网络问题导致的安装失败，解决网络问题后可以顺利安装。
   • 缺点：如果网络本身没有问题，可能无法解决根本原因。
   • 尝试更换镜像源：
   • 优点：国内镜像源通常速度较快，可以有效解决因网络延迟或不稳定导致的安装失败问题。
   • 缺点：有时候镜像源可能会存在数据同步不及时的情况，但这种情况相对较少。
   • 检查包的可用性：
   • 优点：能直接确认包本身的状态，如果包有问题可以及时发现并寻找替代方案。
   • 缺点：如果包本身没问题，可能还需要继续排查其他潜在原因。
4. 总结：
   首先检查网络连接是否正常，若不正常，确保网络畅通或正确配置代理。若网络正常，尝试更换镜像源来加速包的下载和安装过程。同时，确认包在PyPI上的可用性，排除包本身存在问题的可能性。通过这些步骤逐步排查和解决DataAnalysisToolkit包安装失败的问题。
