centos7下利用pyinstaller打包python程序，生成的执行文件运行报错，如何解决

利用pyinstaller打包，生成的执行文件运行报错，报错结果如下：Traceback (most recent call last): File "<string>", line 22, in <module> File "D:\sourcefile\PyInstaller-2.1\PyInstaller\loader\pyi_importers.py", line 270, in load_module File "/ly_cal/CS_Repo/crawler_cross_etf/src/tmp/main/build/main/out00-PYZ.pyz/client.cal_client", line 21, in <module> File "D:\sourcefile\PyInstaller-2.1\PyInstaller\loader\pyi_importers.py", line 270, in load_module File "/ly_cal/CS_Repo/crawler_cross_etf/src/tmp/main/build/main/out00-PYZ.pyz/proto.base_pb2", line 35, in <module> File "/usr/lib64/python2.7/site-packages/google/protobuf/descriptor.py", line 649, in __new__ _message.Message._CheckCalledFromGeneratedFile()TypeError: Descriptors should not be created directly, but only retrieved from their parent.

首先，那堆apixxx.dll的Warning一般不影响执行，可以不用管。
我曾经遇到过类似的pyi_rth_qt5plugins错误，后来发现PyInstaller似乎是从系统路径查找Qt版本的，把我定义的%QTDIR%下面的dll复制过来了，这个Qt版本又和PyQt的版本不同，所以就冲突了。从系统路径去掉Qt以后再生成一切正常。
总之：如果系统中同时安装了Qt和PyQt，或者有好几个Qt/PyQt版本，一定要小心避免引起混乱。
