我正在尝试将python Flask Web api部署到azure门户,但遇到依赖项安装问题,如下图所示。
我已经将扩展 -Python 3.5.4 x64 添加到我的 Azure Web 应用程序中,并且还对所有依赖项使用最新版本,如您在requirements.txt 文件中看到的那样。
我也尝试过从 Azure Kudu DebugConsole 安装/升级安装工具,但这会导致访问被拒绝的问题。

Type 'cls' to clear the console

最佳答案
在 Azure WebApps 上,您无权在除 D:\home
之外的路径 D:\
下执行任何写入操作。因此,当您想为 D:\Python34
中的默认 python 运行时安装 pip 时,会导致错误 PermissionError Access is returned
。
唯一的方法是通过 Kudo 安装 Python 站 pip 扩展并配置 web.config
以使用它而不是默认的扩展。有一个现有 SO 线程的答案 Why is the azure app service django deploy keep failing?里面介绍了安装方法,您可以引用解决。
现在,我看到你已经安装了这个扩展,但是你调用的 python 命令仍然是默认的。解决办法如下。
- 通过命令
set PATH=D:\home\Python34;%PATH%
更改环境变量path
以覆盖默认变量。 - 在 Kudo DebugConsole 中更改当前目录并移动到路径
D:\home\Python34
中,然后就可以直接调用新安装的python
了。
希望有帮助。
