我正在尝试流星http://meteor.com/examples/leaderboard

我必须使用Windows上熟悉的CURL。

现在，我尝试在Ubuntu 12.04上安装它。

但是我得到这些错误：

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？

解决了它：

我做了这个命令

sudo sed -i -e 's/us.archive.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list

然后我可以做sudo apt-get update，然后sudo apt-get install curl

成功安装curl。

更新：

很抱歉出现明显的错误。我昨天也尝试过，在那里我键入了正确的命令，这给了我这个错误信息：

kevin@ubuntu:~$ sudo apt-get install curl
[sudo] password for kevin:

更新2：

更新3：sudo apt-get update在我运行 更新之前，它做了吗。

但这无济于事。

回答不同的更新

第一个问题

您需要命令

sudo apt-get install curl

在安装中使用的命令丢失：sudo apt-get curl因为apt-get的没有一个命令将不起作用curl。

第一次更新

您还想先运行update：

sudo apt-get update

您可能要考虑使用以下命令：

sudo apt-get install libcurl3 php5-curl

它也可能与您使用的php版本有关（php5-common？），请参见此处。

第二次更新

或者，要使其变得更简单，只需使用命令wget https://install.meteor.com | sh。Curl用于较早版本的ubuntu。它并不是真正必要的工具，但是某些教程确实使用了它。

如果收到未找到curl软件包的错误消息，则必须在安装它之前添加如下存储库：

sudo add-apt-repository ppa:ondrej/php
sudo apt update
