无法在android手机上部署应用程序（reportlab问题）

Question

我尝试在手机上部署的应用程序在我的桌面PC上运行良好。我使用以下命令在手机上部署了它：

buildozer android debug deploy run

当我尝试在手机上运行应用程序时，它崩溃了。使用：

adb logcat | grep python

我得到了以下错误：

ModuleNotFoundError: No module named 'reportlab'

我通过编辑buildozer.spec文件“解决了它”：

# (list) Application requirements
# comma separated e.g. requirements = sqlite3,kivy
requirements = python3,kivy,reportlab

但是，当我再次尝试部署应用程序时，我得到了：

我的理解是buidozer正在尝试下载reportlab但失败了。我正在考虑手动下载reportlab，并将其放在适当的文件夹中。不管怎样，我不知道该怎么做；我也不确定它是否解决了我的问题。任何帮助/暗示都将不胜感激

如果你仍然有这个问题，我也有同样的问题，不幸的是，我仍然没有找到更好的方法来解决这个问题。最后，我只是这样做了：

1. 转到您安装的位置reportlab。在我的例子中，这是：~/home/samdev/repo/venv/myproject/lib/python3.7/site-packages
2. 在那里，将文件夹：reportlab和reportlab.libs复制到根项目文件夹中，然后
3. 在buildozer.spec{}中将reportlab作为dep删除

现在应该没问题了
