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

在用pyinstaller打包exe時，出現

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

嘗試了網友說的一系列方法，無果。。。
我發現了錯誤提示裏面的介個：

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之後就把mpl-data分離出去了，我查看了下本身的matplotlib版本

行，卸載，重裝（在anaconda prompt裏）

pip uninstall matplotlib
pip install matplotlib==3.1.1

ok,安裝好新的版本以後從新打包

pyinstaller -F XXX.py

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

再繼續執行

pyinstaller -F XXX.spec

ok,打包完畢
執行時，會出現warning，可是不影響結果~
bingo~ 但願對你有幫助，我弄了幾個小時了，大哭！！！
