brew install python/matplotlib 不工作：没有名为 _tkinter 的模块答案

【问题标题】：brew install python/matplotlib not working: No module named _tkinterbrew install python/matplotlib 不工作：没有名为 _tkinter 的模块

【问题描述】：

我正在努力在 matplotlib 中制作基本图。看起来我没有正确安装 tkinter，据我所知应该从 --with-tcl-tk 标志安装。什么可能导致我的错误？我怎样才能更好地诊断这个问题？下载ActiveState tkinter 对我没有帮助。

我卸载然后重新安装了我认为相关的所有内容。 brew 没有引发错误。

$ brew uninstall python
$ brew uninstall matplotlib numpy --force
$ brew install python --with-tcl-tk
$ brew install numpy matplotlib --with-tcl-tk

但是，当我导入 pyplot 时出现错误：

【解决方案1】：

这比卸载方法快一点（希望更安全）...

1) 确保您已安装 Brew 的 Tcl/Tk（它与 MacOS 分开）

brew install tcl-tk

2) 现在重新编译启用 Tcl/Tk 的 Python

brew reinstall python --with-tcl-tk

【讨论】：

我认为 brew reinstall python --with-tcl-tk 在带有 tcl-tk 8.6.9 的 Homebrew 2.1.10 中失败。有可能吗？

【解决方案2】：

就我而言，我通过使用自制软件卸载并重新安装 Python 解决了这个问题。我希望有更好的解决方案，其他人可以提供...

Pip and setuptools have been installed. To update them
  pip install --upgrade pip setuptools

You can install Python packages with
  pip install <package>

They will install into the site-package directory

Pip 保留了一切，我使用的 venv 也完好无损。
