Azure ImportError 上的 Python 外部未找到模块

Question

如果我使用 python main.py 在本地运行我的代码，则此错误会在本地发生。如果我使用 python3 main.py 运行它，它会按预期工作。我怀疑我的 azure app 服务没有运行正确版本的 python，但是，它设置为 python 3.4

更新

所以我在 kudo 中进入调试控制台并运行 python -m pip install --upgrade -r d:\home\site\wwwroot\requirements.txt.

这是错误

 ERROR: b"'xslt-config' is not recognized as an internal or external command,\r\noperable program or batch file.\r\n" ** make sure the development packages of libxml2 and libxslt are installed ** Using build configuration of libxslt

其中一个要求是需要 libxml2 和 libxslt 的 Pillow。但是我尝试过使用轮子，但没有成功。

更新二 我尝试安装 virtualenv，因为它不存在并且我收到权限错误。

更新 III 我运行了这个命令

D:\home\python364x64>python -m pip install newspaper3k

我在本地测试了所有内容，并且效果很好。我在下面推送并收到此错误。

Answer 1

根据我的经验，我们无权修改D:\home 环境。

所以，最好使用 python 扩展。在这种情况下，请按照以下步骤操作：Azure Flask Routes Not found 并使用命令python -m pip install newspaper 在 python 扩展中安装附加包。

请确保您要安装的软件包必须与 python 扩展的版本匹配。否则会报如下错误。

希望对你有帮助。
