---

笔者使用的python版本为3.8.5

pyinstaller版本为4.3

matplotlib版本为4.3

问题

Runtime Error Could not find the matplotlib data files

常见解决方案
 

许多网络上的解决方案如下: 就是降低matplotblib的版本，笔者原本matplotlib的版本为4.3

pip install matplotlib==3.0.3

pip install matplotlib==3.1.3

笔者同事降低为3.0.3错误依旧；

降低为3.1.3成功

其他解决方案

找到你的python安装的pyinstaller的hooks文件夹中的hook-matplotlib.py文件：

修改文件中文本旧有内容：

datas = [ (mpl_data_dir, "mpl-data"), ]

改为:

datas = [ (mpl_data_dir, "matplotlib/mpl-data"), ]

# 使用UE或者文本编辑器打开hook-matplotlib.py文件

# 内容如下，修改之后保存即可；

from PyInstaller.utils.hooks import exec_statement

mpl_data_dir = exec_statement(
    "import matplotlib; print(matplotlib._get_data_path())")

datas = [
    (mpl_data_dir, "mpl-data"),
]

---

Find and edit the hook-matplotlib.py inside of lib/site-packages/pyinstaller/hooks

edit the data section from: datas = [ (mpl_data_dir, "mpl-data"), ]

to

datas = [ (mpl_data_dir, "matplotlib/mpl-data"), ]
