TypeError:在使用Pyinstaller转换.py时，应为str、bytes或os.PathLike对象，而不是WindowsPath

Question

尝试使用Pyinstaller构建.exe时，引发以下错误：

我在Stackoverflow上找到了一个解决方案，它指出需要在Pyinstaller文件夹中的backend.py中插入一个代码。但这也不起作用

这里出了什么问题

Answer 1

这是目前matplotlib的一个问题

我通过编辑源文件解决了这个问题。如果您不想编辑源文件，据说可以安装较低版本的matplotlib，如3.0.3，以避免此问题

我觉得我的案子不管用。不管怎样，下面是我采取的步骤

第一个开放Python解释器&；复制作为输出得到的路径

>>> import matplotlib
>>> matplotlib.get_data_path() # copy the below path
'C:\\<Python Path>\\lib\\site-packages\\matplotlib\\mpl-data'

接下来，打开文件C:\<Python Path>\lib\site-packages\PyInstaller\hooks\hook-matplotlib.py。为了安全起见，如果需要，请备份此文件

from PyInstaller.utils.hooks import exec_statement

# old line; delete this
mpl_data_dir = exec_statement(
    "import matplotlib; print(matplotlib.get_data_path())")

# Add this line
mpl_data_dir = 'C:\\<Python Path>\\lib\\site-packages\\matplotlib\\mpl-data'

assert mpl_data_dir, "Failed to determine matplotlib's data directory!"

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

别忘了存钱

Answer 2

因此，我发现matplotlib是问题所在。排除Pyinstaller中模块参数中的该选项后，修复了该问题

像这样：

pyinstaller exclude-module matplotlib main.py
