【中文标题】警告：找不到库：Qt5WebKitd.dll、Qt5Cored.dll pyinstaller

【英文标题】：WARNING: lib not found: Qt5WebKitd.dll, Qt5Cored.dll pyinstaller

【发布时间】：2020-06-20 08:14:04

【问题描述】：

我正在将 python 脚本编译为 .exe。但输出返回某种缺失的库。我尝试使用 --path 将路径更改为 python qt/bin 但同样的错误。我尝试了基于控制台的、窗口化的、onefile 甚至 pyinstaller 中的所有内容。但同样的问题。当我使用 python 运行脚本时，它可以正常工作。

使用 Python 运行 Python 脚本时的屏幕截图

我从编译后的 .exe 运行时的屏幕截图

import sys
from PyQt5.QtWidgets import QMainWindow,QApplication,QLineEdit,QPushButton,QTabWidget,QVBoxLayout,QWidget
from PyQt5.QtWebKitWidgets import *
app=QApplication(sys.argv)
tabs=QTabWidget()
tabs.resize(400,300)
mainWindow=QMainWindow()
widget=QWidget()
mainWindow=QMainWindow()
mainWindow.setWindowTitle("Sprotechs")
web=QWebView()
web.load(QUrl("https://google.com"))

verticalLayout=QVBoxLayout()
verticalLayout.addWidget(web)

widget.setLayout(verticalLayout)
mainWindow.setCentralWidget(widget)
mainWindow.show()

sys.exit(app.exec_())

错误输出

【参考方案1】：

您是否尝试过创建python virtual environment，然后安装所有需要的软件包并使用 pyinstaller？这可能会起作用，甚至输出的可执行文件也非常苗条。

【讨论】：

是的，我已经做了 Python 虚拟环境，但还是一样。

【参考方案2】：

确保将 DLL 的路径添加到环境 PATH 变量中。看起来 pyinstaller 在搜索您拥有的所有依赖项时无法找到此 dll，因此在运行时尝试启动您的应用程序时它无法找到。

在某些情况下，它可能只是 pyinstaller 的错误，因此需要使用 --add-data 选项手动添加 dll：https://pyinstaller.readthedocs.io/en/stable/usage.html（更多详细信息）

测试一切是否正常的一种基本方法是在创建的 _MEIxxxxxx 临时文件夹中手动添加 dll 并重新启动 exe。
