Mujoco 入门步骤：缺少 Simulate.cpp 的共享库答案

【问题标题】：Getting started steps with Mujoco: Missing shared libraries with Simulate.cppMujoco 入门步骤：缺少 Simulate.cpp 的共享库
【发布时间】：2017-08-14 07:06:20
【问题描述】：

我正在尝试从 ubuntu 17.04（最新版本）安装 Mujoco（没有成功）。

指令网址：Getting started

版本：mjpro150 linux 和/或 mjpro140 linux

我已经有许可证了。

按照步骤：

将带有激活密钥的 mjkey.txt 放在 bin = ok 上

运行模拟.cpp = 错误

情况：

wil@Ophelia:~/Documents/mjpro150/bin$ ls
basic       libglewegl.so     libglfw.so.3         mjkey.txt  test
compile     libglewosmesa.so  libmujoco150nogl.so  record
derivative  libglew.so        libmujoco150.so      simulate

路径

wil@Ophelia:~/Documents/mjpro150/bin$ pwd
/home/wil/Documents/mjpro150/bin
wil@Ophelia:~/Documents/mjpro150/bin$ LD_LIBRARY_PATH=/home/wil/Documents/mjpro150/bin
wil@Ophelia:~/Documents/mjpro150/bin$ echo $LD_LIBRARY_PATH
/home/wil/Documents/mjpro150/bin

Mujoco的命令步骤和ERROR

wil@Ophelia:~/Documents/mjpro150/bin$ ./simulate
./simulate: error while loading shared libraries: libmujoco150.so: cannot open shared object file: No such file or directory
wil@Ophelia:~/Documents/mjpro150/bin$ ./simulate.cpp
bash: ./simulate.cpp: No such file or directory
wil@Ophelia:~/Documents/mjpro150/bin$ ./simulate ../model/humanoid.xml
./simulate: error while loading shared libraries: libmujoco150.so: cannot open shared object file: No such file or directory

试图编译？！（开始）

/usr/bin/ld: error in simulate(.eh_frame); no .eh_frame_hdr table will be created.

问题：有人知道我如何进行吗？

【问题讨论】：

标签： c++ bash shared-libraries bin openai-gym

【解决方案1】：

试运行

LD_LIBRARY_PATH=. ./simulate ../model/humanoid.xml

作为一个整体（即在 shell 中按回车键之前将所有这些字符粘贴到同一行中）在bin 下作为密码，或至少

export LD_LIBRARY_PATH=/home/wil/Documents/mjpro150/bin

在致电./simulate 之前。您必须导出一个环境变量以使其对从（相同）shell 启动的另一个程序可见。
