Conda仅卸载一个软件包和一个软件包 [英] Conda uninstall one package and one package only

问题描述

当我尝试从conda虚拟环境中卸载pandas时，我看到它也尝试卸载更多软件包:

$ conda uninstall pandas
Using Anaconda Cloud api site https://api.anaconda.org
Fetching package metadata: ....
Solving package specifications: .........

Package plan for package removal in environment /Users/amelio/anaconda/envs/py35:

The following packages will be downloaded:

    package                    |            build
    ---------------------------|-----------------
    dask-0.7.6                 |           py35_0         276 KB

The following packages will be REMOVED:

    blaze:       0.10.1-py35_0
    odo:         0.5.0-py35_1
    pandas:      0.18.1-np111py35_0
    seaborn:     0.7.0-py35_0
    statsmodels: 0.6.1-np111py35_1

The following packages will be DOWNGRADED:

    dask:        0.10.1-py35_0      --> 0.7.6-py35_0

Proceed ([y]/n)?

我只想卸载pandas ，并且不进行其他任何降级.

我知道这些软件包对熊猫pandas甚至对特定版本都有依赖项，但是使用conda甚至可以做到吗? /p>

部分动机

我的理解是，>安装使用conda从GitHub打包.至少它不如使用pip可以使用单线那么简单.

由于我要使用master中的版本，因此我的计划是卸载conda版本，并使用pip从官方仓库GitHub上的主服务器安装pandas.

我该怎么做?

解决方案

您可以使用conda remove --force.

文档说:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

When I try to uninstall pandas from my conda virtual env, I see that it tries to uninstall more packages as well:

$ conda uninstall pandas

    dask:        0.10.1-py35_0      --> 0.7.6-py35_0

Proceed ([y]/n)?

I would like to uninstall pandas only and not have anything else downgraded.

I understand that there these packages have dependencies to pandas and even to specific versions of pandas, but is this even possible at all with conda?

Partial motivation

My understanding is that it isn't that easy to install a package from GitHub using conda. At least it isn't as easy as using a one-liner as one can do with pip.

Since I want to use the version in master, my plan is to uninstall the conda version and use pip to install pandas from master on the official repo GitHub.

How can I do this?

解决方案

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state
