Answer 1

适用于 Python 3.7 的 Pyinstaller

尝试下面的安装正在运行 python 3.7 版

pip install pyinstaller==4.0 --no-build-isolation

Answer 2

我在公司防火墙后面，遇到了同样的问题。 通常，我会通过使用 --proxy 参数调用 pip 来安装一个新的 python 包，但不知何故对于 pyinstaller 来说这还不够。

解决方案是，在调用 pip 之前，我必须在命令提示符会话中设置 http_proxy 和 https_proxy 环境变量。

在命令提示符中：

设置 http_proxy=YourProxyAddress:YourProxyPort

设置 https_proxy=YourProxyAddress:YourProxyPort

pip --proxy YourProxyAddress:YourProxyPort install pyinstaller
