CX_FREEEZE,INNO:找不到matplotlib数据文件

Question

我从python脚本和cx_freeze创建了一个可执行文件.冷冻看起来还不错.但是,当我使用INNO创建设置文件时,我遇到了问题.我可以创建设置并成功部署应用程序.但是当我从"Program Files(x86)"目录启动它时,我遇到了运行时错误:无法找到matplotlib数据文件

C:\Program Files (x86)\GLADDataExtraction>main

    raise RuntimeError('Could not find the matplotlib data files')

我非常广泛地在互联网上寻找解释而没有成功.有很多主题链接到py2exe但没有链接到cx_freeze.我调查了我的cx_freeze setup.py文件,如下所示:

有很多评论,因为我试图尽可能简化setup.py文件,而不会影响构建目录.发射后

python setup.py build

在DOS窗口中,创建目录'build/exe ...'.里面有:

• 带有许多软件包的library.zip文件(matplotlib在里面,但没有mpl-data,因为没有init .py文件,所以看起来不像包.)
• 许多.pyd文件
• 4目录:imageformats,mpl-data,tcl,tk.mpl-data有其内容.

然后,使用"Program Files(x86)"目录中的INNO应用程序创建我的安装文件.我使用此安装文件启动安装.看起来不错.我的程序目录是用很少的目录和文件创建的.来自"C:\ Python27\Lib\site-packages\matplotlib\mpl-data"的文件属于这些文件.但是当我启动.exe文件时,我遇到错误"RuntimeError:找不到matplotlib数据文件".

我的配置是:

• WINDOWS 7 64位
• python 2.7 64位
• cx_freeze 4.3.3
• inno 5.5.5
• PyQt4中

谢谢托马斯，是的，我在安装程序之前首先运行冻结的 exe。还可以。我找到了一个解决方案：在导入目录时，inno将所有文件复制到与exe文件相同的目录（Program Files（x86）目录）中。但是，如果我定义与 freeze exe 相同的目录，则必须在路径 Dest dir 中添加 mpl-data。在 iss INNO 脚本中：
脚本中的行是：

\build\exe.win-amd64-2.7\mpl-data\*"; DestDir: "{app}"; Flags: ignoreversion recursesubdirs createallsubdirs

我在 iss 文件的路径中添加 mpl-data 目录，以便在安装目录和冻结目录中从 exe 到 mpl-data 文件具有相同的相对路径：

\build\exe.win-amd64-2.7\mpl-data\*"; DestDir: "{app}\mpl-data\"; Flags: ignoreversion recursesubdirs createallsubdirs

我编译，安装......它有效
