无法在python2.7.18上安装pyinstaller

Question

我使用python2.7.18轮更新，pip也。但我还是会犯同样的错误。在相同版本的linux上，但是在windows上会出现一个错误。如何纠正此错误？

在python3中，有许多不同的更改可能使pyinstaller上的新版本无法在python2上工作。要解决这个问题，您必须执行以下操作之一：

• Install Python3或
• 安装支持python2.7的特定pyinstaller版本，更新最多的版本是3.6.

。

pip install pyinstaller==3.6

我还强烈建议不要使用python 2，因为它已经到了生命的尽头，而且大多数人都使用python 3。对于少数使用python 2的人，他们这么做是因为他们好奇，想运行一些旧代码，或者将旧程序移植到python 3中。(如果您想为python3安装installed，并且安装了两个python版本)

pip3 install pyinstaller

这将告诉程序，您使用的是python 3的pip，而不是python 2。我希望这会有所帮助！
