- 运行 chromedriver 在 mac 上时出错- 不是有效标识符 - IPv4 端口不可用

Question

当我尝试运行 Chromedriver.exe 时，终端出现此错误。用于网页抓取。 Java 开发包有问题吗？

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

/Users/mac/Desktop/URBAN/winterbreak2018/web_scraping/chromedriver ; exit;

Answer 1

很可能 Chromedriver 没有正确关闭，除非有其他东西使用该端口。

运行 usr/libexec/java_home -V 查看甚至使用了哪个虚拟机。
