- 在 Mac 上运行 chromedriver 时出错 - 不是有效的标识符 - IPv4 端口不可用

Question

当我尝试运行Chromedriver.exe进行网页抓取时，我在终端上遇到此错误。Java 开发工具包有问题吗？

-bash: export: `/Library/Java/JavaVirtualMachines/jdk-11.jdk/Contents/Home': **not a valid identifier**

Answer 1

很可能

Chromedriver没有正确关闭，除非其他端口使用该端口。

运行usr/libexec/java_home -V以查看甚至使用了哪个 VM。
