我有一个脚本，我在它的前面附加了一个GUI，并希望将它分发给其他DnD DM，让他们用来将网格覆盖到图像上。唯一的问题是，每次我尝试使用Pyinstaller打包python脚本时，它都会抛出两个不同的错误。如果我运行pyinstaller --hidden-import matplotlib myscript.py，它会返回
NameError: name 'defaultParams' is not defined
[7532] Failed to execute script ImageGridder
因此，我决定使用--onefile选项再次尝试运行该命令。当我这样做时，它会返回，
RuntimeError: Could not find the matplotlib data files
[18884] Failed to execute script ImageGridder
现在，在这两个示例中，打包过程都完成了，所有文件似乎都正确生成了。只是当我运行它生成的.exe时，它就崩溃了。我知道文件本身运行正常，因为我已经让它在我的台式机和笔记本电脑上正常运行和工作。我花了好几个小时寻找任何有帮助的东西，但似乎什么都不起作用。脚本本身，

使用--onefile命令时警告文件的内容：
This file lists modules PyInstaller was not able to find. This does not
necessarily mean this module is required for running you program. Python and
Python 3rd-party packages include a lot of conditional or optional modules. For
example the module 'ntpath' only exists on Windows, whereas the module
'posixpath' only exists on Posix systems.
Types if import:
* top-level: imported at the top-level - look at these first
* conditional: imported within an if-statement
* delayed: imported from within a function
* optional: imported within a try-except-statement
IMPORTANT: Do NOT post this list to the issue-tracker. Use it as a basis for
yourself tracking down the missing module. Thanks!

您可以尝试通过安装旧版本的matplotlib包来解决此问题。例如：
pip install matplotlib==3.2.2
在--onefile模式中，基于PyInstaller贡献者的此提交，它引用https://github.com/pyinstaller/pyinstaller/issues/5004，您可以修改PyInstallerhookshook-matplotlib.py，使其具有：
datas = [
(mpl_data_dir, "matplotlib/mpl-data"),
]
而不是
datas = [ datas = [
(mpl_data_dir, "mpl-data"),
]
我遇到了相同的错误：
NameError: name 'defaultParams' is not defined
我使用pyinstaller4.0(开发版本(解决了上述错误。
您可以在此处下载pyinstaller开发版本：https://github.com/pyinstaller/pyinstaller
下载后，你可以通过pip安装它，如下所示：
cd [download dir] #change directory to donwloaded and unziped dir
pip install .
我遇到了同样的问题：RuntimeError：在另一个conda环境中工作时，找不到matplotlib数据文件。
因此，我参考了我的基本环境设置来解决工作环境中的问题：
Matplotlib为3.1.1，PyInstaller为3.6。我的Python版本是3.7.7。
pip install matplotlib==3.1.1
pip install pyinstaller==3.6
您可以坚持使用当前的matplotlib版本，但必须更新pyinstaller(5.0.dev0(:
pip install -U https://github.com/pyinstaller/pyinstaller/archive/develop.zip
我试着按照其他人的建议更改hook-matplotlib.py文件，但事实证明最新版本的Pyinstaller已经有了这些更改，所以只要你的Pyinstaller更新了，你就应该在这方面做得很好(通过运行pip install pyinstaller --upgrade进行检查(
然而，我仍然遇到"无法确定matplotlib的数据目录！"问题，并能够通过以下方式解决：
- 运行
pip uninstall pathlib
这是一个奇怪的包，但(不幸的是(Python世界中有两个pathlib包：一个是内置的，另一个是PyPi上的。如果您偶然使用PyPi，hook-matplotlib.py中的get_data_path()函数将无法按预期工作，并将导致该断言失败
- 在Pyinstaller命令中，包括
--hidden-import matplotlib
不确定这个是否100%必要，但我在pyinstaller命令中包含了它，以确保正在使用matplotlib钩子文件(例如：pyinstaller --onefile --windowed --hidden-import "matplotlib" ...
希望这是有帮助的，这个决议真的很令人沮丧，以找出
