windows安装texlive报错xz: (stdin): Compressed data is corrupt、TLPDB::_install_package: untar failed

因项目需要将注释导出成PDF文档，使用doxygen工具，但是该工具只能到处letex脚本，需要运行脚本生成PDF，运行脚本又需要letex支持，于是又需要安装texlive。texlive的安装，很多教程，不再记录。记录一下安装过程中出现的问题。

全都是解压错误：xz: (stdin): Compressed data is corrupt和TLPDB::_install_package: untar failed

搜索好久找不到原因，最后看到有人提到msys冲突了，终于解决。
所以如果你安装了msys，又要安装texlive，只需要 $\color{red}{先将msys的路径从环境变量的path中移除}$ 。再完全重新安装就OK了。
