背景
一直使用IDEA突然到期不能使用了，重裝後也不行。
解決
打開 /Applications/IntelliJ IDEA.app/Contents/MacOS
發現有idea*
然後執行 ./idea
2020-05-24 10:59:10.503 idea[7944:601495] allVms required 1.8*,1.8+

Error: could not find libjava.dylib
Failed to GetJREPath()

這次有了報錯信息就好解決了 如上idea.vmoptions文件有問題，所以證明我一開始還是刪錯了文件。
打開文件刪除我們加的代理的那句話。再次保存重新打開idea發現可以使用了。
希望對大家有幫助
