问题
I am getting the following errors with webdriver-manager update. My protractor is at version 5.1.1
my_local_windows_directory>webdriver-manager update
events.js:160 throw er; // Unhandled 'error' event ^
Error: write EPROTO 101057795:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:openssl\ssl\s23_clnt.c:794:
at exports._errnoException (util.js:1022:11) at WriteWrap.afterWrite (net.js:801:14)
Any ideas to resolve this issue. I am behind a corporate Lan, but I tried BYOD network as well, but still this did not resolve.
回答1:
1) Restart mac
2) Run this -> webdriver-manager update
3) Run this -> webdriver-manager start
4) Also you can check your ports sudo lsof -iTCP -sTCP:LISTEN -n -P
