conda ValueError：无法解析 Cpython sys.version

Question

我正在尝试在 Windows 7 64 位系统上的现有 Python 环境（32 位）上安装 Anaconda（32 位）。我能够让 Anaconda python 环境运行，但导航器不会响应并且 conda 命令失败并出现错误

ValueError: 解析 CPython sys.version 失败

我已删除 C:\Python27; C:\Python27\脚本；来自 PATH 变量，但我一定遗漏了什么！

我只是更新了系统环境变量 PATH，并没有触及 PythonPath，它被设置为 C:\Python27。这就是该 ValueError 的原因。我找到了我的解决方案in this stackoverflow answer。
