终端用着用着，光标消失了。 iterm2 仓库issues给出提示，要在设置》高级里面，Use system cursor icons when possile 为 yes. 然而上面的设置并没有用。 然后看了superuser上的question, 给出提示, 直接在终端输入 reset , 光标就会出现。解决了问题。 reset 参考 https://gitlab.com/gnachman/iterm2/-/issues/6623 https://superuser.com/questions/177377/os-x-terminal-cursor-problem
学习matplotlib绘图时，代码如下，执行过后，图片弹窗没有弹出。 import matplotlib.pyplot as plt import matplotlib plt.plot([1.6, 2.7]) plt.show() 并且有下面的报错 cannot load backend ‘qt5agg’ which requires the ‘qt5’ interactive framework, as ‘headless’ is currently running 看起来似乎是backend没有设置有关。查了些资料，设置了还是不行。 最后偶然发现，我执行python 都是在tmux里面执行的，如果不再tmux会话里面执行，图片就能正常显示。 问题从设置backend, 切换到tmux的会话。 查到sf上正好有相关的问题，可能是在tmux里面PATH环境变量引起的问题。 问题给的建议是把下面的代码写入.bashrc中， If you’re on a Mac and have been wondering why /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin keeps getting prepended to PATH when you run tmux, it’s because of a utility called path_helper that’s run from your /etc/profile file. You can’t easily persuade tmux (or rather, bash) not to source /etc/profile (for some reason tmux always runs as a login shell, which means /etc/profile will be read), but you can make sure that the effects of path_helper don’t screw with your PATH....
