打包matplotlib出现RuntimeError: Could not find the matplotlib data files

在用pyinstaller打包exe时，出现

pyimod03_importers.py:493: MatplotlibDeprecationWarning: Matplotlib installs where the data is not in the mpl-data subdirectory of the package are deprecated since 3.2 and support for them will be removed two minor releases later.
  exec(bytecode, module.__dict__)

RuntimeError: Could not find the matplotlib data files

尝试了网友说的一系列方法，无果。。。
我发现了错误提示里面的介个：

MatplotlibDeprecationWarning: Matplotlib installs where the data is not in the mpl-data subdirectory of the package are deprecated since 3.2 and support for them will be removed two minor releases later.

ok，matplotlib3.2以后就把mpl-data分离出去了，我查看了下自己的matplotlib版本

行，卸载，重装（在anaconda prompt里）

pip uninstall matplotlib
pip install matplotlib==3.1.1

ok,安装好新的版本之后重新打包

pyinstaller -F XXX.py

找到.spec文件
修改 hiddenimports=[‘matplotlib’],

再继续执行

pyinstaller -F XXX.spec

ok,打包完毕
执行时，会出现warning，但是不影响结果~
bingo~ 希望对你有帮助，我弄了几个小时了，大哭！！！
