windows环境变量引发的血案

最近重装了系统，决心使用Anaconda来管理python包和虚拟环境。在完成一系列配置后，运行程序，发现老是报错

D:Anaconda3envsjobnote>python E:workspaceJobNoteApi
un.py
Traceback (most recent call last):
  File "E:workspaceJobNoteApi
un.py", line 2, in <module>
    from app import create_app
  File "E:workspaceJobNoteApiapp\__init__.py", line 3, in <module>
    from flask import Flask, request
  File "D:Anaconda3envsjobnotelibsite-packagesflask\__init__.py", line 21, in <module>
    from .app import Flask, Request, Response

    import _ssl             # if we can't import it, let the error propagate
ImportError: DLL load failed: 找不到指定的模块。

网上找了好多方法都解决不了，昨天突然自己好了，也没找到问题所在。

今天早晨来，又不行了，还是报错。突然想起来是不是环境变量造成的，echo %path%打印出环境变量来，吓人一跳

D:Anaconda3envsjobnote>echo %path%
D:Program FilesVanDyke SoftwareClients;C:Windowssystem32;C:Windows;C:WindowsSystem32Wbem;C:WindowsSystem32WindowsPowerShellv1.0;C:WindowsSystem32OpenSSH;C:Program FilesJavajdk1.8.0_144in;C:Program FilesJavajdk1.8.0_144jrein;%conda_home%;%conda_home%Scripts;%conda_home%Libraryin;d:Program FilesGitcmd;C:UsersqpandAppDataLocalMicrosoftWindowsApps;

之前做的conda_home变量根本没有被解析出来，重新设置了一下，看到变量已经恢复。重新运行程序，恢复正常。

具体环境变量为什么没有解析出来，还有待研究
