用PyInstaller实现Python中的exchangelib库失败

Question

我正在编写一个应用程序，该应用程序将连接到Exchange，并按计划向收件人发送电子邮件。此应用程序依赖于成功的导入exchanglib。

当我将程序作为.py文件执行时，我能够导入exchangelib并获得所需的所有组件。我可以从命令行和朱庇特笔记本成功地运行它，但是当我使用PyInstaller将它转换成可执行文件时，它就失败了。

以下是相关代码行：

print("Attempting: import exchangelib")
try:
    import exchangelib
    print("SUCCESS: import exchangelib")
except Exception as expOutput:
    print("FAILED: import exchangelib")
    print(expOutput)

print("Attempting: from exchangelib import DELEGATE, Account, Credentials, Configuration, Message, Mailbox, FileAttachment, HTMLBody")
try:
    from exchangelib import DELEGATE, Account, Credentials, Configuration, Message, Mailbox, FileAttachment, HTMLBody
    print("SUCCESS: import DELEGATE, Account, Credentials, Configuration, Message, Mailbox, FileAttachment, HTMLBody")
except Exception as expNewOutput:
    print(expNewOutput)

当我从.py文件(Test_exchangelib.py)运行这个文件时，我得到了我所期望的：

"SUCCESS: import exchangelib"
"SUCCESS: import DELEGATE, Account, Credentials, Configuration, Message, Mailbox, FileAttachment, HTMLBody"

当我以exe的形式运行它时，我会得到以下输出：

    Attempting: import exchangelib
    FAILED: import exchangelib
    module 'zoneinfo' has no attribute 'ZoneInfoNotFoundError'
    Attempting: from exchangelib import DELEGATE, Account, Credentials, Configuration, Message, Mailbox, FileAttachment, HTMLBody
    module 'zoneinfo' has no attribute 'ZoneInfoNotFoundError'

下面是我的PyInstaller命令，用于将Test_exchangelib.py转换为可执行文件：

C:\>cd C:\Users\aguler\AppData\Roaming\Python\Python37

C:\Users\aguler\AppData\Roaming\Python\Python37>ProjectEnvironment\Scripts\activate.bat

(ProjectEnvironment) C:\Users\aguler\AppData\Roaming\Python\Python37>Scripts\pyinstaller --onefile C:\PyFiles\Email_Troubleshoot\Test_exchangelib.py --paths=C:\Users\aguler\AppData\Roaming\Python\Python37\site-packages\tzdata --paths=C:\Users\aguler\AppData\Roaming\Python\Python37\site-packages\tzdata\zoneinfo --paths=C:\users\aguler\appdata\roaming\python\python37\projectenvironment\lib\site-packages\exchangelib --paths=C:\Users\aguler\AppData\Roaming\Python\Python37\ProjectEnvironment\Lib\site-packages\backports

在通过调用exchangelib实现的account.py文件中，从backport调用zoneinfo类。这意味着可执行文件没有正确地引入后端，因为它忽略了zoneInfo。

我遗漏了什么？如何将整个backports库放入可执行文件中？

Answer 1

错误消息意味着Python可以找到zoneinfo模块，但是zoneinfo.ZoneInfoNotFoundError不存在。因此，要么安装了一个非常旧的backports.zoneinfo版本(类为在0.1.0版中引入)，要么从一些不是backports.zoneinfo包的东西中获取zoneinfo模块--例如，如果您的路径中有一个zoneinfo.py文件。
