1.第一步：先输入：   cd /Applications/PyCharm.app/Contents/MacOS

2.第二步：查看无法打开pycharm的原因，需要输入：c./pycharm

3.第三步:下面就是展示的分析日志：其中许多小伙伴都找不到 网上说的这个地址“cd /Users/用户名/Library/Preferences/PyCharm2019.1/”

其实地址不是这个，而是  /Users/liuxiaoming/Library/Application Support/JetBrains/PyCharm2020.1/pycharm.vmoptions

上面地址中的Application Support 是无法直接打开的  需要把这个做下处理变成 Application\ Support/

也就是说需要输入：cd /Users/用户名/Library/Application\ Support/JetBrains/PyCharm2020.1/

即可找到 pycharm.vmoptions

4.第四步：直接删除即可: rm -f pycharm.vmoptions

这样pycharm就可以重新打开了

 

注：该问题我查了好多资料都没解决，直达我重新分析它的这个分析日志：
