Question

顺便说一句，我很高兴在火炬上运行AlexNet;现在我想安装 distlearn 来扩展模型。我已按照说明设置我的代理变量，使用直接wget命令测试它们。似乎luarocks执行序列中的某些内容没有正确导出代理shell变量：使用简单的命令

sudo luarocks install autograd

我收到错误

Missing dependencies for autograd:
totem 

Using https://raw.githubusercontent.com/torch/rocks/master/totem-0-0.rockspec... switching to 'build' mode
Cloning into 'torch-totem'...
fatal: unable to connect to github.com:

Error: Failed installing dependency: https://raw.githubusercontent.com/torch/rocks/master/totem-0-0.rockspec - Failed cloning git repository.

我尝试使用git clone下载repos（autograd，thrift，dataset，ipc），现在我得到了：

$ luarocks install distlearn

......和......

我是否潜入错误的兔子洞？我需要修理什么？我需要获得更多诊断信息吗？

Answer 1

rockspec代码有一个内置的默认使用git协议的要求。从防火墙后面，必须使用HTTPS。 luarocks没有代理环境变量来从命令行配置它，因此安装失败。

幸运的是，是一种重新配置 git 的方式：

sudo git config --global url."https://".insteadOf git://

这会强制所有git协议引用使用HTTPS。安装成功，我的模型代码运行到第一次编码失败的程度。

无法通过防火墙安装distlearn
