python - 无法在 Conda 环境中安装 Gensim - 找不到 noarch 目录

Question

我正在 Conda 环境中的远程服务器上工作。所以我之前安装了 Gensim 并一直在使用它，但前几天我遇到了这个错误:

没什么大不了的，我只需再次!conda install即可:

import sys

!conda install --yes --prefix {sys.prefix} gensim
Solving environment: ...working... failed

CondaHTTPError: HTTP 404 NOT FOUND for url <https://conda.anaconda.org/noarch/noarch/repodata.json>
Elapsed: 00:00.438028
CF-RAY: 4b676bdb1fa378c8-LAX

The remote server could not find the noarch directory for the
requested channel with url: https://conda.anaconda.org/noarch

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>.

好的，让我们按照指示操​​作:

mkdir noarch
A subdirectory or file noarch already exists.

echo '{}' > noarch/repodata.json

bzip2 -k noarch/repodata.json
  File "<ipython-input-5-cad6ef02410f>", line 1
    bzip2 -k noarch/repodata.json
                  ^
SyntaxError: invalid syntax

请教谷歌博士:显示 channel

!conda config --show channels
channels:
  - noarch
  - conda-forge
  - K183152
  - k183152
  - win-64
  - default
  - pysoundfile
  - loopbio
  - defaults

!conda config --add channels
usage: conda config [-h] [--json] [--debug] [--verbose]
                    [--system | --env | --file FILE]
                    (--show [SHOW [SHOW ...]] | --show-sources | --validate | --describe [DESCRIBE [DESCRIBE ...]] | --write-default | --get [KEY [KEY ...]] | --append KEY VALUE | --prepend KEY VALUE | --set KEY VALUE | --remove KEY VALUE | --remove-key KEY | --stdin)
conda config: error: argument --prepend/--add: expected 2 arguments

!conda config --get
--set auto_update_conda False
--add channels 'defaults'   # lowest priority
--add channels 'loopbio'
--add channels 'pysoundfile'
--add channels 'default'
--add channels 'win-64'
--add channels 'k183152'
--add channels 'K183152'
--add channels 'conda-forge'
--add channels 'noarch'   # highest priority
--set ssl_verify True

好吧，至少我可以在自己的机器上编写代码——哇，它在我的 Jupyter Notebook 中降级了 Python:

嗯，也许 Gensim 不会安装，因为 NumPy 或 SciPy 没有安装？ - 此时真的是在黑暗中拍摄:不，他们很好

我仍然遇到同样顽固的 noarch 目录请求 channel 错误 - 我不知道如何解决请帮忙 :(

Answer 1

我想我明白了 - 那些添加的 channel 必须离开。导航到 .condarc 我在我的用户目录中找到它并在记事本中编辑它。删除那些 channel 并保存。
