python3.7：（Pyttsx3）没有名为“pyttsx3”的模块

我有一个用 Windows 编写的程序（使用模块 pyttsx3），我曾经在 python3.7 上运行它，它曾经运行良好。
但是，当我尝试在 Ubuntu 20.04 上运行它时，它无法运行。
我的 Ubuntu 20.04 PC 上安装了 python3.8.2 和 python3.7.7，使用 python3.8.2 解释器运行该程序会出现以下错误：

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/pyttsx3/__init__.py", line 20, in init
    eng = _activeEngines[driverName]
  File "/usr/lib/python3.8/weakref.py", line 131, in __getitem__
    o = self.data[key]()
KeyError: None

During handling of the above exception, another exception occurred:

    self._handle = _dlopen(self._name, mode)
OSError: libespeak.so.1: cannot open shared object file: No such file or directory

另一方面，使用 python3.7 解释器运行它会出现以下 ModuleNotFoundError：

.
.
.
import pyttsx3
ModuleNotFoundError: No module named 'pyttsx3'

...但是，当我使用命令检查已安装的模块时pip3 list，pyttsx3 出现在列表中，版本为：2.87

现在，我很茫然！...不知道该怎么办。

更新-1 (pipenv)

我尝试pipenv使用以下命令运行它，如@ivan-borshchov 在回答中所建议的那样：

pipenv --three
pipenv install pyttsx3
pipenv run python3 MyPythonFile.py

...但是这会出现以下错误，这些错误与我使用 python3.8.2 解释器时遇到的错误有些类似。

更新-2（pipenv 运行 python3.7...）

好吧，在摆弄的时候pipenv，我发现在 pipenv 中运行 python3.7 再次出现了 ModuleNotFoundError，与我在没有 pipenv 的情况下在 python3.7 中运行程序时遇到的一样（尽管我已经在 pipenv 中安装了 pyttsx3，如 UPDATE-1 部分所述）。

所以，我很好奇是否可以在 pipenv 中的 python3.7 中安装 pyttsx3（而不是在 pipenv 中的 python3 中）。

答案1

尝试在以下位置运行您的项目pipenv：

pipenv --three
pipenv install pyttsx3 
pipenv run python3 yourfile.py

它将为您提供一个清晰的环境，因此可以更轻松地跟踪问题，而不会受到其他解释器的影响

答案2

首先前往地点：

C:\Users\username\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\PyInstaller\hooks

创建一个新文件hook-pyttsx3.py。

在此文件中，复制以下代码。

""" pyttsx3 imports drivers module based on specific platform. Fount at https://github.com/nateshmbhat/pyttsx3/issues/6 """

hiddenimports = [
    'pyttsx3.drivers',
    'pyttsx3.drivers.dummy',
    'pyttsx3.drivers.espeak',
    'pyttsx3.drivers.nsss',
    'pyttsx3.drivers.sapi5', ]

然后，在您的脚本中使用此脚本：

import pyttsx3
from pyttsx3.drivers import sapi5

参考
