我正在尝试使用 pyinstaller（版本 3.3.1）打包（冻结）一个 python3 应用程序

运行pyinstaller my_script.py后失败并显示导入错误列表，其中第一个错误如下：

292 INFO: checking Analysis
292 INFO: Building Analysis because out00-Analysis.toc is non existent
292 INFO: Initializing module dependency graph...
298 INFO: Initializing module graph hooks...
299 INFO: Analyzing base_library.zip ...

File "/usr/local/Cellar/python3/3.6.4_2/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site.py", line 544, in <module>
main()
...

...并继续出现更长的导入错误列表这可能是我的 python3 配置或 pyinstaller 规范文件的问题。我目前使用的是默认的 pyinstaller 规范文件。以下是我正在测试的系统：

• MacOSX 10.13.3 (High Sierra)
• Python 3.6.4（使用 brew 安装）
• pyinstaller 3.3.1（使用pip安装）

非常感谢您的帮助。

当我尝试安装fastai( pip install fastai) 时，出现以下错误：

AttributeError: module 'enum' has no attribute 'IntFlag'

我需要将python代码编译为exe。我找到了一些如何做到这一点的指南，其中要求我为此安装 PyInstaller：

pip install --upgrade pyinstaller

但我收到下一个错误：

我用pyqt4做了一个程序。我试图通过 pyinstaller 创建一个可执行文件。但我失败了，我继续寻找原因。最后发现pyinstaller不支持pyqt4。于是我安装了pyqt5，把代码改成了pyqt5。但是pyinstaller还是报错，一定程度上解决了问题。我什至删除了pyqt4。但是我仍然没有解决下面的问题。

AttributeError: 模块“enum”没有属性“IntFlag”

我在这里阅读并尝试了所有评论：为什么Python 3.6.1抛出AttributeError：模块'enum'没有属性'IntFlag'？但仍然没有帮助。

我正在使用Pycharm Pycharm 2018.3 Community Edition，而我的Python版本是3.7

每次尝试为Pycharm设置解释器时，都会出现此错误：
