Python I'；我试图使用pip安装pyinstaller，但它'；s给我这个错误：ImportError:没有名为'；bz2&x27；

我重新安装了所有python版本（2.7、3.4和3.6），不再出现“编码”错误，但出现了另一个问题

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

您能提供更多详细信息吗？您如何准确地使用

pip

？您能发布完整的错误跟踪吗？我正在尝试安装pyinstaller。我解决了另一个问题，但它仍然不起作用，错误现在是：importError:没有名为“bz2”的模块。@juanpa.arrivillaga
