我正在尝试使用 pip 安装 pyinstaller，但它给了我这个错误： ImportError: No module named 'bz2'

Question

我重新安装了我拥有的所有 python 版本（2.7、3.4 和 3.6）并且我不再收到“编码”错误，但另一个问题出现了。

我正在尝试安装 pyinstaller，我运行 pip install pyinstaller 但它给了我：

You are using pip version 6.0.8, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting pyinstaller
  Using cached PyInstaller-3.2.1.tar.bz2

  During handling of the above exception, another exception occurred:
