无法在 Anaconda 中 pip 安装包

问题描述

刚刚在 Mac OSX Mavericks 上下载并安装了 anaconda 3.6.2，我需要安装一个未预装 anaconda 的包 seaborn.

Just downloaded and installed anaconda 3.6.2 on Mac OSX Mavericks and I need to install a package seaborn which is not pre-installed with anaconda.

$ conda install seaborn
Fetching package metadata: ..
Error: No packages found in current osx-64 channels matching: seaborn

You can search for this package on Binstar with

    binstar search -t conda seaborn

You may need to install the Binstar command line client with

    conda install binstar

接下来我尝试使用pip来安装包

Next I tried to use pip to install the package

$ which pip
/Users/username/anaconda/bin/pip

$ pip install seaborn
Could not find an activated virtualenv (required).

尝试再次激活 root Anaconda env，但还是不行

Tried activating root Anaconda env again, but still does not work

$ source activate root
discarding /Users/username/anaconda/bin from PATH
prepending /Users/username/anaconda/bin to PATH

$ pip install seaborn
Could not find an activated virtualenv (required).

接下来我尝试激活一个 virualenv 并且 pip install 工作正常.

Next I tried activating a virualenv and pip install works.

workon testEnv
pip install seaborn

现在我从 Anaconda 的启动器启动了 iPython notebook.但是seaborn包好像没有找到！

Now I launched iPython notebook from Anaconda's launcher. But the seaborn package does not seem to be found!

seaborn 包真的安装了吗?

在 ~/bashprofile 中，我有:

# virutalenvwrapper
export WORKON_HOME=$HOME/.virtualenvs
source /Users/username/.virtualenvs/datasci/bin/virtualenvwrapper.sh

# added by Anaconda 2.0.1 installer
export PATH="/Users/username/anaconda/bin:$PATH"

<小时>

更新

删除了 2 个 virtualenvwrapper 行，重新加载了 .bash_profile，但 pip install 仍然给出错误 Could not find anactivated virtualenv (required). 激活另一个 conda 环境 source activate testenv 没有帮助.

---

Update

Removed the 2 virtualenvwrapper lines, reloaded .bash_profile, but pip install still gives the error Could not find an activated virtualenv (required). Activating another conda environment source activate testenv does not help.

$ source activate ~/.bash_profile
$ pip install seaborn
Could not find an activated virtualenv (required).

$ source activate testenv
discarding /Users/username/anaconda/bin from PATH
prepending /Users/username/anaconda/envs/testenv/bin to PATH
$ pip install seaborn
Could not find an activated virtualenv (required).

推荐答案

需要安装anaconda版本的pip.运行:

You need to install the anaconda version of pip. Just run:

conda install pip

这将在激活的 conda 环境中安装 pip

This will install pip inside of the activated conda environment
