无法运行pyinstaller捆绑的基于QT的GUI应用程序，控制台输出显示它是由于导入错误引起的：
ImportError: unable to find Qt5Core.dll on PATH
最初，pyqt5 / pyqt和pyinstaller来自公寓。我试图从pypi重新安装pyqt5和pyinstaller，但不能解决问题。
我检查了pyinstaller dist目录，它包含所有需要的dll。当我在conda env中时（启动conda控制台，然后在控制台中运行捆绑的应用程序），捆绑的应用程序将正常运行。我检查了加载的dll，它们都在dist目录或系统默认目录中。
我在windows 10 x64 [Ver 10.0.18362.175]上，Python版本是miniconda的3.7.3。

假设您并非绝对需要PyQt5版本5.13.0，最简单的修复方法是使用以下命令将PyQt5降级到5.12.2版本：
pip install pyqt5 == 5.12.2
，您的可执行文件将按预期工作。
答案 1 :(得分：2)
升级到Qt5.13后遇到同样的问题。
在pyinstaller github上找到了此解决方案
您需要修改.spec文件并放入以下内容：
from collections import namedtuple
IdxRange = namedtuple('IdxRange', 'min max')
def range_size(idx_range): # ex range_size(IndexRange(0, 10)) = 10
return idx_range.max - idx_range.min
def range_is_contained_in(inner, outer):
return (outer.min <= inner.min <= inner.max <= outer.max)
def trim_pos_dict(pos_dict):
idx_ranges = sorted(map(IdxRange._make, pos_dict), key=range_size, reverse=True)
overlapping_ranges = set()
for target in idx_ranges:
overlapping_ranges.update(x for x in idx_ranges
if x != target and range_is_contained_in(x, target))
trimmed_pos_dict = {k: v for k, v in pos_dict.items() if k not in overlapping_ranges}
return trimmed_pos_dict

如问题中所述，当在conda控制台中启动捆绑的应用程序时，该应用程序可以正常运行，由static导出的所有已加载DLL都位于pyinstaller创建的dist目录中。因此，问题在于包含pyqt DLL的路径不在系统的ProcessExplorer环境中。也许这是pyinstaller的错误。解决方法是手动将程序路径添加到系统PATH env。
这是我正在使用的代码片段：

我注释了文件site-packages\PyQt5\__init__.py的所有内容，然后重新安装。可以。
我将python3.5与PyInstaller=3.5和PyQt5=5.13.0一起使用。打包的exe在我的计算机上可以运行，但不能在其他计算机上运行。错误消息是：
File "anaconda3\lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 627, in exec_module
File "site-packages\PyQt5\__init__.py", line 41, in <module>
File "site-packages\PyQt5\__init__.py", line 33, in find_qt
ImportError: unable to find Qt5Core.dll on PATH
所以我看到site-packages\PyQt5\__init__.py（5.13.0）是：
def find_qt():
import os
path = os.environ['PATH']
dll_dir = os.path.dirname(__file__) + '\\Qt\\bin'
if os.path.isfile(dll_dir + '\\Qt5Core.dll'):
path = dll_dir + ';' + path
os.environ['PATH'] = path
else:
for dll_dir in path.split(';'):
if os.path.isfile(dll_dir + '\\Qt5Core.dll'):
break
else:
raise ImportError("unable to find Qt5Core.dll on PATH")
try:
os.add_dll_directory(dll_dir)
except AttributeError:
pass
find_qt()
del find_qt
我认为PyQt5在另一台计算机上找不到PATH，尽管Qt5Core.dll已经存在于
直接进行项目。所以我注释掉了文件，现在可以了。

我通过site-packages\PyQt5\__init__.py中的全部注释为自己解决了此问题
并从旧版QT __init__.py中添加以下代码：
import os as _os
_path = _os.path.dirname(__file__) + '\\Qt\\bin;' + _os.environ['PATH']
_os.environ['PATH'] = _path
