量角器不启动硒

Question

我在使用量角器开始端到端测试时遇到以下错误。

我可能是因为启动 webdriver 的问题。我尝试运行 selenium，但出现以下错误

manu@MANU:/mnt/c/Users/Manu/Documents/manu/programs/web/angular/dw-ng2-app$ ./node_modules/protractor/bin/webdriver-manager start
[16:27:55] I/start - java -Djava.security.egd=file:///dev/./urandom -Dwebdriver.chrome.driver=/mnt/c/Users/Manu/Documents/manu/programs/web/angular/dw-ng2-app/node_modules/protractor/node_modules/webdriver-manager/selenium/chromedriver_2.32 -Dwebdriver.gecko.driver=/mnt/c/Users/Manu/Documents/manu/programs/web/angular/dw-ng2-app/node_modules/protractor/node_modules/webdriver-manager/selenium/geckodriver-v0.18.0 -jar /mnt/c/Users/Manu/Documents/manu/programs/web/angular/dw-ng2-app/node_modules/protractor/node_modules/webdriver-manager/selenium/selenium-server-standalone-3.5.3.jar -port 4444
[16:27:55] I/start - seleniumProcess.pid: undefined
[16:27:55] W/start - Selenium Standalone server encountered an error: Error: spawn java ENOENT

我尝试使用带有 webdriver-manager 的 clean 和 start 选项清理和重新启动，但这并没有解决问题

更新--- 我通过 Bash for Windows 在 Windows 机器上运行它。启动 Selenium 的问题是 Bash 找不到 Java。我导出了 Path，但是因为 Java 安装在 Program Files 中，我无法在 Bash 中设置路径，因为 Bash 无法处理 Program Files 中的空间。我可以在设置了 JAVA 路径的 CMD 上运行 selenium 服务器。问题仍然没有解决。

看来问题是我第一次没有正确安装。我应该从主目录运行webdriver-manager update。我使用webdriver-manger clean 清理并从项目的主目录project home> .\node_modules\protractor\bin\webdriver-manager start 重新运行webdriver-manger start。如果使用其他目录，安装可能会设置一些路径，这些路径会变得混乱。我还从项目的主目录>node .\node_modules\protractor\bin\protractor .\protractor.conf.js开始了量角器
