使用 pyinstaller 后执行编译文件“No module named 'scipy._lib.messagestream'”时出错

Question

在从 python 2.7 升级到 3.6 并同时迁移到 scipy 1.0.0 之后，我正在尝试使用 pyinstaller 编译我们的代码 https://bitbucket.org/OES_muni/massiveoes。我正在使用 64 位 win7 机器。程序本身运行良好，pyinstaller 运行没有错误，但是当我尝试运行构建 exe 文件时，它给了我这个错误：

Answer 1

好的，以下解决了我的直接问题：编辑 pyinstaller .spec 文件以使用 Scipy 添加以下隐藏导入：

 hiddenimports=['scipy._lib.messagestream']
