这是我收到的特定错误消息。 我不确定为什么会这样，有人可以帮忙吗？这是通过使用pip install pyinstaller和下面建议的所有3条命令来完成的。

Answer 1

这是由issue in pip 19引起的。目前唯一的解决方法是降级到18.1点：

$ pip install pip==18.1

$ pip --version
pip 18.1 from ...\lib\site-packages\pip (python 3.7)

然后您可以安装pyinstaller 3.4：

$ pip install pyinstaller

获取要求构建轮...错误

由菲利普Belemezov答案是为我工作。下面是该问题的重现和屏幕截图形式的工作解决方案，供您更好地理解。

解决方案

1. pip install pip==18.1-以管理员身份运行命令提示符，它将为您安装pip版本18.1，如下所示。

1. pip install pyinstaller-现在运行此命令，它将安装module：pyinstaller，如下所示。

1. 最后一步是在命令中键入pyinstaller，如果输出相似，则意味着您已经成功安装了package：pyinstaller。

Answer 3

我遇到了同样的问题并尝试了很多从互联网上获得的方法，但以下对我有用

1. 以管理员身份打开命令提示符
2. 将 pip 降级到 18.1 版 pip install pip==18.1
3. 下载 pyinstaller 3.4 版 pip install pyinstaller==3.4
4. 成功，这应该可行。使用 pyinstaller -v
验证安装

Answer 4

降级 pip 对我也不起作用。从 conda 安装运行良好。 尝试 - 'conda install -c conda-forge pyinstaller'
