Chaquopy Android 导入错误

Question

我在尝试为 Android 测试 Chaquopy 时遇到 ImportError: No module named six。似乎与 this question 有关，但据此应该已修复。我可以在 .zip 存档中看到 six.py 文件，并且我已经在我的 python 发行版中安装了六个。

这里是 java 代码：

protected void onResume() {
    super.onResume();

    if (! Python.isStarted()) {
        Python.start(new AndroidPlatform(activity));//error is here!
        myInstance = Python.getInstance();
    } else {
        myInstance = Python.getInstance();
    }

    myTextView = (TextView) findViewById(R.id.textView);
    myButton = (Button) findViewById(R.id.button);

    myButton.setOnClickListener(new Button.OnClickListener() {
        public void onClick(View v) {
            //Do stuff here
            String tt = myInstance.toString();//placeholder
            myTextView.setText(tt);
        }
    });
}

编辑：

我还添加了相关的 gradle 行并重新安装 python 所以它使用默认路径（之前使用 Anaconda）。

这是由于无意中依赖了应用程序内置的 six 造成的。它已在版本 0.4.5 (https://github.com/chaquo/chaquopy/issues/13) 中修复。
