无法为 Ubuntu 安装 LightTable

Question

我得到了 Ubuntu 14.04，真的很想试试 LightTable。但甚至不能安装它。我遇到的所有麻烦都是关于 leiningen 的。

我像manual said一样复制了这个步骤，没有任何错误：

First install or update leiningen.

Download the lein script. For Windows, download lein.bat.
Place it on your $PATH where your shell can find it (eg. ~/bin).
Set it to be an executable (chmod a+x ~/bin/lein).
Run the Lein script (eg. "./lein" or "sh lein") without quotes.

在那之后，我尝试了接下来的步骤：

git clone https://github.com/LightTable/LightTable.git
cd LightTable
bash linux_deps.sh

但我得到的只是：

Please install leiningen before running this script.

如果我跑：

lein version 

我收到：

bash: /usr/bin/lein: No such file or directory

./lein 的结果是：

我做错了什么？我还需要做什么才能成为 LightTable 用户？

Answer 1

您安装了 Java 吗？ Leiningen 需要它，但在其main page 的安装说明中未提及。他们只在GitHub 的安装说明中提到它。您还需要安装 cURL，但这是针对 LightTable 本身的，而不是 Leiningen。

在安装 OpenJDK（Java 7 版本）、Leiningen、Git 和 cURL 之后，我只能在 Ubuntu 14.04 上安装和运行 LightBox，所以希望你只是缺少类似的东西。

Answer 2

这部分：

bash: /usr/bin/lein: No such file or directory

是因为找不到命令，是不是在那个目录下？您在个人资料的 $PATH 中添加了什么？我在猜测，但我认为您需要将其正确添加到您的 $PATH 环境中。如果你运行

env

显示什么？

Answer 3

要从 ubuntu 32bit 或 64bit.do 中删除 lighttable，

sudo rm -r /opt/LightTable /usr/bin/lighttable
