conda ValueError：无法解析Cpython sys.version

问题描述：

我想在Windows 7 64位系统上的现有Python环境（32位）上安装Anaconda（32位）。我能得到水蟒蟒环境中运行，但是导航仪不会响应和畅达命令失败，出现错误conda ValueError：无法解析Cpython sys.version

ValueError: failed to parse CPython sys.version

我已删除C：\ Python27; C：\ Python27 \脚本;来自PATH变量，但我必须错过一些东西！

我只更新了系统环境变量PATH，并没有碰到PythonPath，它被设置为C：\ Python27。这是ValueError的原因。我找到了我的解决方案in this stackoverflow answer。
