安裝conda后，將包管理鏡像修改為國(guó)內(nèi)源
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes
在下載pydeseq2前，先創(chuàng)建一個(gè)名為pydeseq2的虛擬環(huán)境
conda create -n pydeseq2

解決過(guò)程
出現(xiàn)這個(gè)報(bào)錯(cuò)應(yīng)該是之前設(shè)置的鏡像不能用了
首先顯示所有channel
conda config --show channels
存在兩個(gè)channel，一個(gè)默認(rèn)channel，一個(gè)是之前添加的channel
channels:
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
- defaults
因?yàn)橹霸O(shè)置的這個(gè)清華源channel已經(jīng)不能用了，才導(dǎo)致報(bào)錯(cuò)，所以先刪除這個(gè)channel
conda config --remove channels?https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
再次檢查現(xiàn)存channel, 發(fā)現(xiàn)之前添加清華源channel已經(jīng)刪除
conda config --show channels
## channels:
- defaults
添加可用的清華源channel
conda config --add channels?rsync://mirrors.tuna.tsinghua.edu.cn/anaconda/
conda config --add channels?https://repo.continuum.io/
conda config --set show_channel_urls yes
設(shè)置conda config --set show_channel_urls yes可以在從channel中安裝包時(shí)顯示channel的url，這樣就可以知道包的安裝來(lái)源了。
問(wèn)題沒(méi)有解決，待續(xù)
根據(jù)CSDN中
Conda創(chuàng)建環(huán)境失?。篊ondaHTTPError: HTTP 000 CONNECTION FAILED-CSDN博客
仍然報(bào)錯(cuò)，但是報(bào)錯(cuò)代碼變了
CondaHTTPError: HTTP 404 NOT FOUND for url <https://mirrors.jlu.edu.cn/noarch/repodata.json>
Elapsed: 00:00.181423
The remote server could not find the noarch directory for the
requested channel with url: https://mirrors.jlu.edu.cn
As of conda 4.3, a valid channel must contain a `noarch/repodata.json` and
associated `noarch/repodata.json.bz2` file, even if `noarch/repodata.json` is
empty. please request that the channel administrator create
`noarch/repodata.json` and associated `noarch/repodata.json.bz2` files.
$ mkdir noarch
$ echo '{}' > noarch/repodata.json
$ bzip2 -k noarch/repodata.json
You will need to adjust your conda configuration to proceed.
Use `conda config --show channels` to view your configuration's current state.
Further configuration help can be found at <https://conda.io/docs/config.html>.
