推荐答案

ErrorAction 无处不在的参数可用于使用参数值 SilentlyContinue 和它可用于使用参数值 Stop 将非终止错误转换为终止错误.但是，它无法帮助您忽略终止错误，在这种情况下，Stop-Transcript 会引发终止错误.如果您想忽略，请使用 try/catch 例如:

The ErrorAction ubiquitous parameter can be used to silence non-terminating errors using the parameter value SilentlyContinue and it can be used to convert non-terminating errors to terminating errors using the parameter value Stop. However it can't help you ignore terminating errors and in this case Stop-Transcript is throwing a terminating error. If you want to ignore, use a try/catch e.g.:

try { Stop-Transcript } catch {}
