一. conda踩坑记录1.An unexpected error has occurred. Conda has prepared the above report

想更新deeptools，但是发现无论如何都下载不了，并且有以下报错

future releases of conda.
Would you like conda to send this report to the core maintainers?

[y/N]: y
Upload successful.

Thank you for helping to improve conda.
Opt-in to always sending reports (and not see this message again)
by running

    $ conda config --set report_errors true

按照二. conda install安装不了任何包，报一大段错误
方法，还是不行，并且出现了新的报错

继续找解决办法
Python&aconda系列：conda创建虚拟环境、切换环境 报错中的`三. conda create, conda install, conda update报错

(atac) vip9t07@tpm9-desktop:~$ conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge
(atac) vip9t07@tpm9-desktop:~$ conda config --set show_channel_urls yes

光删除了conda-forge的镜像源依然不能解决问题

继续

四. CondaHTTPError: HTTP 000 CONNECTION FAILED for url ＜https://mirrors.tuna.tsinghua.edu.cn/anaconda

将中科大的镜像源加入并删除其他清华镜像源及default

(atac) vip9t07@tpm9-desktop:~$ vim ~/.condarc
(atac) vip9t07@tpm9-desktop:~$ cat ~/.condarc
channels:
  - https://mirrors.ustc.edu.cn/anaconda/pkgs/free/
  - https://mirrors.ustc.edu.cn/anaconda/cloud/bioconda/
show_channel_urls: true

可以了！
(当然这只是我以为的可以了，实际上后续还经历了一系列醉生梦死的艰辛求知路……）

解决办法：

1、有人说是防火墙的问题，输入conda config --set ssl_verify false

还是不行

2、有人说conda损坏，重装，，，，想想还是算了，太麻烦

3、终极解决办法：输入 conda clean -i

完美解决！！

三. Conda无法安装或更新的问题

用conda安装任何东西都报错. 开始怀疑是公司的鬼网络问题.

将.condarc重命名, 重新尝试, 一切又很正常, 以为是清华源TUNA的问题, 还想去https://github.com/tuna/ 报错.

后来一次将https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r channel一行在.condarc中删掉后, 一切又正常了. 莫名其妙啊…

最开始时怀疑是 raise UnavailableInvalidChannel(self.url_w_repodata_fn, 404)的问题, 以为是清华源那边缺失channeldata.json导致找不到subdir, 但关键的文件是repodata.json还是存在且一样的. 可能不是TUNA的问题.

• 官方pkgs/r源 https://repo.anaconda.com/pkgs/r

• 清华pkgs/r源 https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r/

于是重新仔细追查错误, 发现这个错误有三处:

• raise UnavailableInvalidChannel(self.url_w_repodata_fn, 404)

• raise Response304ContentUnchanged()

• json.decoder.JSONDecodeError: Unterminated string starting at: line 184947 column 5 (char 5586731)

第一个网络是可以下载对应repodata.json的, 第二个304重定向应该不是, 第三个是json解码的问题. 搜了一下, 找到以下帖子:

JSONDecodeError with on-disk corrupted repodata #7190

噢, 原来还是公司网络的锅. 肯定是之前update repo信息时网络有问题, 于是就出现了污染.

解决办法

conda clean -i

然后重新随便install 个东西, 会重新下载repo信息. 问题解决. NND的公司网络…

附错误内容:

$ conda install numpy
Collecting package metadata (current_repodata.json): failed

原因：连不上清华的镜像。

按照网上的方法删除 -default 也没有用。

修改方法：

使用下面两个命令，将中科大的镜像加到目录中去

$conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/free/
$conda config --set show_channel_urls yes

然后打开./删除其他所有镜像，以及default

$vim ~/.condarc

修改前：

修改后：

然后就可以了！

看网上有人说，把https 改为http也行，没试，不知道可行否
