推荐答案

按照

As per the documentation, the default chrome location to be auto-detected by cypress is "C:/Program Files (x86)/Google/Chrome/Application/chrome.exe". If the other version of chrome is installed in a different location, I guess the available options are to uninstall both 79 & 70 and clean install 70 first to the above said location and later installing 79 to a different location (OR) uninstall 79 (assuming it installed in default location) and re-install to a different location than the default, and finally set a symbolic link to version 70 on the default location something like (which requires admin previleges on the machine, though). This way cypress scans the default location and gets whichever version pointing to the symbolic link.

mklin "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" "path to ver70 exe"

但是，毕竟，我认为命令参数似乎略有不同，您可以尝试一下(确保路径指向版本70，而不是默认版本)

But before all, I think the command parameters appear to be slightly off, can you try instead (making sure the path is pointing to the verion 70, not the default one)

npx vue-cli-service test:e2e --headless --browser "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"

我怀疑--headless是'cypress run'命令的默认命令，如果您的test:e2e类似于"cypress run"，那么您可以简单地忽略它.

I suspect --headless is default for a 'cypress run' command command, if your test:e2e is something like "cypress run", then you can simply omit it.
