linux运行spyder出错：段错误 (核心已转储)和错误ERROR conda.core.link:_execute(502)

记录改错的点滴。

linux安装anaconda后运行spyder，在anaconda2/bin下输入

./spyder

报错：段错误 (核心已转储)

查到一位大佬已解决：

具体是输入如下代码

conda install pyopengl

没想到又报错了：
Preparing transaction: done
Verifying transaction: done
Executing transaction: failed

ERROR conda.core.link:_execute(502): An error occurred while uninstalling package ‘defaults::conda-4.5.4-py27_0’.
OSError(13, ‘Permission denied’)
Attempting to roll back.

Rolling back transaction: done

OSError(13, ‘Permission denied’)

然后又查到另一位大佬的回答：https://stackoverflow.com/questions/49181799/conda-update-conda-permission-error
输入如下代码：

sudo chown -R username:username /home/username/anaconda2

把username改掉，例如我自己运行就是

sudo chown -R jxc:jxc /home/jxc/anaconda2

运行完这一条代码然后再运行

conda install pyopengl

./spyder

应该就可以解决了。
