上述方法莫名失败了，这种可以: ``` WARNING: The Python sqlite3 extension was not compiled. Missing the SQLite3 lib? zipimport.ZipImportError: can't decompress data; zlib not available ``` 配置临时变量： ``` export LDFLAGS="-L/usr/local/opt/zlib/lib -L/usr/local/opt/sqlite/lib" export CPPFLAGS="-I/usr/local/opt/zlib/include -I/usr/local/opt/sqlite/include"...

为了兼容 `pyenv` 环境下的代码兼容性问题： 我添加了如下代码 ```python import matplotlib matplotlib.use('TkAgg') ```

解决方案 ：(替换渲染引擎) 1. 安装PyQt5 `pip3 install PyQt5` 2. 设置 `backend`： ` backend: Qt4Agg` ```python echo "backend: Qt4Agg" >> ~/.matplotlib/matplotlibrc ``` 或者 ```python vim ~/.matplotlib/matplotlibrc ``` 添加： ``` backend: Qt4Agg ```

新的渲染图：
