当我使用下载dgl环境的时候，出现
CondaError: Failed to write to /data/xxx/.conda/pkgs/mkl-2021.4.0-h06a4308_640.conda
errno: 28
Errno 28\] No space left on device InvalidArchiveError("Error with archive /data/xxx/.conda/pkgs/libgfortran5-11.2.0-h1234567_1/.cph_tmp42_mjil9/pkg-libgfortran5-11.2.0-h1234567_1.tar.zst. You probably need to delete and re-download or re-create this file. Message from libarchive was:\\n\\nFailed to create dir 'share'") 很明显是没有使用空间了，需要清理一下缓存。于是使用命令 conda clean --all 进行清理。  是的！没看错！我居然吧tempfiles文件和logfile文件都清理了！！！ 但是到这我并没有在意，毕竟再次安装dgl成功了。但运行程序发现又出现了新的错误： INTEL MKL ERROR: /data/xxxx/.conda/envs/regcn/lib/python3.8/site-packages/mkl/../../../libmkl_core.so.1: invalid ELF header. Intel MKL FATAL ERROR: Cannot load libmkl_core.so.1. 于是我卸载mkl，又进行了重装。结果又说找不到dgl了。 ModuleNotFoundError: No module named 'dgl' 我只能再重新安装dgl。但dgl成功安装之后，又出现了上述的mkl错误，，，出于好奇的心里，我再次卸载mkl，这次错误不一样了，出现了一长串conda环境错误： Collecting package metadata (repodata.json): failed # \>\>\>\>\>\>\>\>\>\>\>\>\>\>\>\>\>\>\>\>\>\> ERROR REPORT \<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\< Traceback (most recent call last): File "/home/xxx/anaconda3/lib/python3.9/site-packages/conda/core/xxx.py", line 232, in _load mtime = getmtime(self.cache_path_json) File "/home/xxx/anaconda3/lib/python3.9/site-packages/conda/core/xxxx.py", line 200, in cache_path_json ...

这时候我才发现我的tmp文件没有了！！！
当我conda create -n xxx的时候 同样也会出现上述的错误。。。。
于是我修改了环境变量
nano ~/.bashrc 修改环境
在最后一行加入 export TMPDIR=/你的tmp地址
source ~/.bashrc 重启环境
检查
成功解决conda环境问题
