conda报错

Posted 2023-05-03

参考技术A 1.Permission denied: '/home/ccy/anaconda3/lib/python3.7/site-packages/astor'

Consider using the `--user` option or check the permissions.

原因：可能是由于conda版本不一致冲突引起，可使用命令：conda update -n base -c defaults conda

进行版本号更新尝试解决。

解决：在使用pip安装时候，增加--user选项，

2.bantu其他软件离线安装

可以先用apt-get install 进行安装，安装成功后会得到安装源文件包，

放在/var/cache/apt/archives目录下，把所有的文件复制出去，然后需要安装的时候，在其存放目录下，运行sudo dpkg -i xxx.deb  即可。

3.pip安装速度太慢

可以更换清华软件源，具体为pip install -i https://pypi.tuna.tsinghua.edu.cn/simple some-package（临时使用）

4.conda环境和pip环境都可以移植，但是前提是已经创建了虚拟环境。所以，如果需要复制本机的环境，注意先创建conda环境。

5.当运行命令：conda install 或者 conda uninstall 时，报错：Solving environment: failed。

解决方法是添加 Anaconda Python 免费仓库：

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

conda config --set show_channel_urls yes

在主机上的服务器里用miniconda安装新环境时，输入
conda create -n name python==x.x.x时安装失败，遇到了An unexpected error has occurred. Conda has prepared the above report.问题。.

解决方法一（用此方法解决）参考链接

一、输入以下代码，查看是否存在.condarc文件。

$ conda config --show-sources

出现以下代码，就代表根目录下自动生成了.condarc文件

==> /home/wangchunxiao/.condarc <==

二、如果生成了此文件，将此文件删除

rm -rf ~/.condarc

预备方法

1、关闭VPN！（在用上面的方法时，我已经提前将VPN关掉了，不知道原理但是可以试试。）参考链接
2、尝试输入以下命令行。（尝试过了，没有奏效也没出别的大事）参考链接

conda clean -i
#这句话的目的是删除缓存和索引。

3、尝试输入以下命令行。（没有尝试，看起来很吓人，不敢动！）参考链接

conda clean --packages && conda clean --all && conda update --all
#清除所有包，清除所有东西，更新所有东西
