首先我安装了curl
:
company@rb-VirtualBox:~$ apt install curl
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?
company@rb-VirtualBox:~$ sudo apt install curl
[sudo] password for company:
Reading package lists... Done

curl is already the newest version (7.68.0-1ubuntu2.7).
0 upgraded, 0 newly installed, 0 to remove and 552 not upgraded.
然后我尝试使用它:
company@rb-VirtualBox:~$ curl -X GET 'http://localhost:9200'
Command 'curl' not found, did you mean:
command 'curl' from deb curl (7.68.0-1ubuntu2.7)
Try: apt install <deb name>
正如您所看到的,它仍然显示“未找到命令'curl'”。
如果我使用完整路径执行它,如下所示:
company@rb-VirtualBox:~$ /usr/bin/curl -X GET 'http://localhost:9200'
然后就可以了
更多信息:
company@rb-VirtualBox:~$ whereis curl
curl: /usr/bin/curl /usr/share/man/man1/curl.1.gz
company@rb-VirtualBox:~$ echo $PATH
/home/company/.nvm/versions/node/v17.8.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
答案1
我不知道为什么,但在调用它之后
company@rb-VirtualBox:~$ /usr/bin/curl -X GET 'http://localhost:9200'
现在突然这也起作用了:
company@rb-VirtualBox:~$ curl -X GET 'http://localhost:9200'
更新:
正如 @jesse_b 在评论中正确假设的那样,这是因为我从网站复制了命令以及一些可疑字符,例如\r
或\n
,这些字符导致了错误。
