[/quote] [b]二. Torch的版本支持[/b] 最新版的Torch支持Ubuntu，Fedora20，Fedora22，Centos7。但不支持Fedora21，Centos6。   [b]三. ubuntu安装Torch[/b][code]# in a terminal, run the commands git clone https://github.com/torch/distro.git ~/torch --recursive cd ~/torch; bash install-deps; ./install.sh[/code]有时候在执行[b]bash install-deps[/b]安装依赖时并未出错，但执行[b]./install.sh[/b]时会出一些错误，解决办法我。 T做了一个汇总，希望能帮助大家：   [b]五. torch安装问题汇总[/b]

1. 错误类似于：[code]nvcc error : '***' died due to signal[/code]解决方案：[b]sudo ./install.sh[/b]

错误2[code]Error: Build error: Failed building. Updating manifest for /root/torch/install/lib/luarocks/rocks fftw3 scm-1 is now built and installed in /root/torch/install/ (license: BSD)[/code] 错误3[code]Error: Failed installing dependency: https://raw.githubusercontent.com/rocks-moonscript-org/moonrocks-mirror/master/luacrypto-0.3.2-1.src.rock - Could not find header file for OPENSSL No file openssl/evp.h in /usr/local/include No file openssl/evp.h in /usr/include You may have to install OPENSSL in your system and/or pass OPENSSL_DIR or OPENSSL_INCDIR to the luarocks command. Example: luarocks install luacrypto OPENSSL_DIR=/usr/local[/code]参照[b]Problem with Torch #86[/b]，执行[code]sudo apt-get install -y libssl-dev[/code]安装libssl-dev，之后重新安装Torch即可。

错误4:

提示缺少依赖lbase64 ，luacrypto，uuid 等，可直接执行如下代码[code]luarocks install missed-package[/code]
