conda默认的cache缓存文件重定向

1. 问题

当使用conda安装包时，搭建轮子会默认使用home目录下的存储，但是有时候一次性安装的包比较多，home目录又小得可怜就会遇到如下报错：

Building wheels forcollected packages: icvi.ete3,pybedtools , docopt, pysamWARNING: BuildingWARNING:BuildingBuildingWARNING:WARNING:Buildingwheel for docopt failed: [Errno 122] Disk quota exceeded:wheel for pysam failed: [Errno 122] Disk quota exceeded:WARNING: BuldingFailed to build jcvi ete3 pybedtools docopt pysamWARNING: There was an error checking the latest version of pip

' /home/yanyuting/.cache/pip/wheels!
ERROR: Could not build wheels for jcvi, ete3, pybedtools, docopt, pysam, which is required to install pyproject.toml-based projects

主要是which is required to install pyproject.toml-based projects没内存弄完的问题

2. 解决

一般就是把home目录下的.cache路径删除掉就行了，或者删掉其他一些不同的文件，给足够的空间，这对于安装小的包其实够用了
但是建议可以直接修改conda的缓存路径，可以在config文件里面修改，也可以通过命令修改

mkdir path/.cache # 在非home目录下的任意盘下面创建cache文件夹
pip config set global.cache-dir path/.cache
# rm -rf home/user/.cache # 删除home目录下的cache文件（optic）
