最近在安装 Pytorch 工具的时候需要用到 conda 来进行安装
在安装 conda 工具的工程中执行安装脚本然后报错
Shell
Copy
bash Miniconda3-latest-Linux-x86.sh
Miniconda3-latest-Linux-x86.sh: line 373: /root/miniconda3/pkgs/python-3.7.1-h0371630_7/bin/python3.7: No such file or directory
进入具体的 conda 安装目录发现这个 python 可执行文件是存在的
直接命令行执行这个可执行文件发现也会报相同的错误
查看文件的权限
Shell
Copy

发现也没有问题
然后想到会不会是具体的可执行文件的问题
查看当前系统的版本信息

发现是 64 位的系统
查看当前可执行文件的信息

miniconda3/pkgs/python-3.7.1-h0371630_7/bin/python3.7: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.32, with debug_info, not stripped
可以看到 ELF 32-bit LSB shared object 这是一个 32 位的可执行文件，所以会发生 No such file or directory 的错误
我们可以通过安装一些 兼容库的方法使 64 位的系统可以运行 32 位的程序

再次执行 conda 的安装，发现已经可以成功安装了
