python - 无法在安卓手机上部署应用（reportlab 问题）

问题描述

我试图在手机上部署的应用程序在我的台式电脑上运行良好。我使用以下命令将其部署在手机上：

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

我收到以下错误：

ModuleNotFoundError：没有名为“reportlab”的模块

我通过编辑buildozer.spec文件“解决了”：

# (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尝试下载reportlab并失败。我正在考虑reportlab手动下载并将其放在适当的文件夹中。无论如何，我不知道该怎么做；我也不确定它是否能解决我的问题。任何帮助/提示将不胜感激。

解决方案

如果您仍然有这个问题，我遇到了完全相同的问题，不幸的是我仍然没有找到更好的方法，所以最后我只是这样做了：

  1. 转到您安装的位置reportlab。就我而言，这是：~/home/samdev/repo/venv/myproject/lib/python3.7/site-packages。
  2. 在那里复制文件夹：reportlab并reportlab.libs进入您的根项目文件夹，然后
  3. reportlab作为 dep in删除buildozer.spec requirements。

现在它应该没有问题
