我正在尝试 Meteorhttp://meteor.com/examples/leaderboard
我必须使用我在 Windows 上熟悉的 CURL。
现在我尝试在 Ubuntu 12.04 上安装它。
但我收到这些错误：
kevin@ubuntu:~$ curl https://install.meteor.com | sh
The program 'curl' is currently not installed. You can install it by typing:
sudo apt-get install curl
kevin@ubuntu:~$ apt-get curl
E: Invalid operation curl
kevin@ubuntu:~$ sudo apt-get curl
[sudo] password for kevin:
E: Invalid operation curl
如何安装 CURL？
解决了：
我执行了这个命令
sudo sed -i -e 's/us.archive.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list
sudo apt-get update然后我可以做sudo apt-get install curl
成功安装了 curl。
更新：
抱歉，我犯了明显的错误。我昨天也试过了，我输入了正确的命令，但却出现了以下错误消息：
kevin@ubuntu:~$ sudo apt-get install curl
[sudo] password for kevin:

更新2：

答案1
不同更新的答案
第一个问题
你需要命令
sudo apt-get install curl
这安装您使用的命令中缺少：sudo apt-get curl无法工作，因为 apt-get 没有命令curl。
首次更新
您还想update先运行：
sudo apt-get update
您可能需要考虑使用此命令：
sudo apt-get install libcurl3 php5-curl
它可能还与您使用的 php 版本有关（php5-common？）请参阅这里。
第二次更新
或者，为了更简单，只需使用命令wget https://install.meteor.com | sh。Curl 在早期版本的 ubuntu 上使用。它并不是一个必不可少的工具，但有些教程确实使用它。
答案2
如果您收到未找到 curl 包的错误消息，则必须在安装之前添加如下存储库：
sudo add-apt-repository ppa:ondrej/php
sudo apt update
