在Anaconda環境中使用pip安裝模塊

Question

我最近已轉換到RHEL6上的Anaconda環境，但是我不需要conda存儲庫中的模塊。 所以我用pip安裝它：

(gt_keys)[user@server gtkey]$ which pip
/srv/home/shared/anaconda/envs/gt_keys/bin/pip

(gt_keys)[user@server gtkey]$ pip install owslib
Downloading/unpacking owslib
Downloading OWSLib-0.8.3.tar.gz (97kB): 97kB downloaded
Running setup.py egg_info for package owslib

Requirement already satisfied (use --upgrade to upgrade): python-dateutil>=1.5 in /srv/home/shared/anaconda/lib/python2.7/site-packages (from owslib)
Requirement already satisfied (use --upgrade to upgrade): pytz in /srv/home/shared/anaconda/lib/python2.7/site-packages (from owslib)
Requirement already satisfied (use --upgrade to upgrade): pytest in /srv/home/shared/anaconda/lib/python2.7/site-packages (from owslib)
Requirement already satisfied (use --upgrade to upgrade): pytest-cov in /srv/home/shared/anaconda/lib/python2.7/site-packages (from owslib)
Requirement already satisfied (use --upgrade to upgrade): PIL in /srv/home/shared/anaconda/lib/python2.7/site-packages/PIL (from owslib)
Requirement already satisfied (use --upgrade to upgrade): cov-core>=1.6 in /srv/home/shared/anaconda/lib/python2.7/site-packages (from pytest-cov->owslib)
Requirement already satisfied (use --upgrade to upgrade): coverage>=3.4 in /srv/home/shared/anaconda/lib/python2.7/site-packages (from cov-core>=1.6->pytest-cov->owslib)
Installing collected packages: owslib
  Running setup.py install for owslib

Successfully installed owslib
Cleaning up...

但這在我的環境中不起作用：

(gt_keys)[user@server gtkey]$ which python
/srv/home/shared/anaconda/envs/gt_keys/bin/python

(gt_keys)[user@server gtkey]$ python -c 'import owslib'
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
    ImportError: No module named owslib

owslib僅適用於基本的Ananaconda安裝：

sh-4.1$ which python
/srv/home/shared/anaconda/bin/python
sh-4.1$ python -c 'import owslib'

我究竟做錯了什么？

Answer 1

我不知道為什么，但是這次成功了：

pip install owslib --allow-external PIL --allow-unverified PIL

我仍然會對我的過程中的任何評論感興趣。 昨晚失敗后，今天早上我重新連接到服務器時，發生了一些奇怪的事情，該問題已解決。 一定是有路徑的。
