我想在GoLang程序中执行二进制文件.
这是我的代码:
package main
import (
"fmt"
"os/exec"
)
func main() {
output, _ := exec.Command("/home/user/Golang/bin/hello").Output()
fmt.Println(output)
}
但我得到的输出为:[]

我已经使用高山linux创建了Jupyter docker镜像。一切工作正常，但容器未暴露端口。但是在容器内部，端口仍在工作。但是我无法从主机访问。
我已经写了如下图的图像文件：
FROM vanarajaz/alpine-python
MAINTAINER Vanaraj C "vanaraj@assistanz.com
"RUN python3 -m pip install --upgrade pip && \
python3 -m pip install jupyter
EXPOSE 8888
CMD [ "jupyter", "notebook" ]
创建容器后，出现以下错误：
[I 13:32:34.019 NotebookApp] Writing notebook server cookie secret to /root/.local/share/jupyter/runtime/notebook_cookie_secret[C 13:32:34.592 NotebookApp] Running as root is not recommended. Use --allow-root to bypass.From:Vanaraj

我不知道如何解决此错误。任何帮助是极大的赞赏。提前致谢。
我有一个用selenium webdriver编写的简单自动化脚本.我需要通过Jenkins执行这个脚本.所以我在Jenkins中配置了这个工作,当试图执行时,我无法打开Firefox浏览器.
控制台输出如下:
Running TestSuite
org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:
Error: cannot open display: :99
Failed tests:

这是我的代码:
@Test
public void testEasy() {
// WebDriver driver = new FirefoxDriver();
WebDriver driver = null;
FirefoxBinary binary = new FirefoxBinary(new File("/usr/bin/firefox"));
binary.setEnvironmentProperty("DISPLAY",System.getProperty("lmportal.xvfb.id",":99"));
driver = new FirefoxDriver(binary,null);
driver.get("https://www.google.co.in/?gfe_rd=cr&ei=drM-V8PiHPPI8AevjriQDA&gws_rd=ssl");
// String title = driver.getTitle();
// AssertJUnit.assertTrue(title.contains("Free Selenium Tutorials"));
// System.out.println("TEST");
