python3.6上的tkinter在arch上有多个版本

Question

我正在尝试测试 tensorflow 对象检测。因为tensorflow需要python3.6，而我的系统默认安装了python3.7.1，所以我从源代码构建了python3.6.7。然后我用 python3.6.7 创建了一个 venv 并安装了我所有的依赖项，但我最终在尝试导入 matplotlib 时出现错误并得到以下错误：  File "detection.py", line 9, in <module>    from matplotlib import pyplot as plt  File "/home/johnmadden/repos/tfobj/lib/python3.6/site-packages/matplotlib/pyplot.py", line 2374, in <module>    switch_backend(rcParams["backend"])  File "/home/johnmadden/repos/tfobj/lib/python3.6/site-packages/matplotlib/pyplot.py", line 207, in switch_backend    backend_mod = importlib.import_module(backend_name)  File "/home/johnmadden/repos/tfobj/lib/python3.6/importlib/__init__.py", line 126, in import_module    return _bootstrap._gcd_import(name[level:], package, level)  File "/home/johnmadden/repos/tfobj/lib/python3.6/site-packages/matplotlib/backends/backend_tkagg.py", line 1, in <module>    from . import _backend_tk  File "/home/johnmadden/repos/tfobj/lib/python3.6/site-packages/matplotlib/backends/_backend_tk.py", line 5, in <module>    import tkinter as Tk  File "/usr/local/lib/python3.6/tkinter/__init__.py", line 36, in <module>    import _tkinter # If this fails your Python may not be configured for TkModuleNotFoundError: No module named '_tkinter'我在网上查看，发现我需要安装 tkpacman -S tk而且我仍然遇到相同的错误，但是当我转到 python3.7.1 时，它成功导入。我认为它正在尝试为 python3.7.1 而不是 python3.6.7 安装它。我知道在 ubuntu 上人们可以做到sudo apt-get install python3-tk这将如何在 arch 上完成？

发现我的问题，我在安装 tk 之前创建了 venv，所以它仍然缺少它。我刚刚重新创建了虚拟环境。
