我正在尝试导出使用conda + pip构建的conda env(通过conda安装),但是缺少一些通过pip安装的软件包。下面是我遵循的详细流程。
我正在运行的操作系统是:
bdauser@testsuselinux:~> cat /etc/os-release
NAME="SLES"
VERSION="12-SP3"
VERSION_ID="12.3"
PRETTY_NAME="SUSE Linux Enterprise Server 12 SP3"
ID="sles"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:suse:sles:12:sp3"
这是我的anaconda版本:
bdauser@testsuselinux:~> conda list anaconda
# packages in environment at /home/bdauser/anaconda3:
#
anaconda 5.0.1 py36hd30a520_1
anaconda-client 1.6.5 py36h19c0dcd_0
anaconda-navigator 1.6.9 py36h11ddaaa_0
anaconda-project 0.8.0 py36h29abdf5_0
我通过以下方式创建并激活了anaconda env:
bdauser@testsuselinux:~> conda create --name libmad python=3.5
bdauser@testsuselinux:~> source activate libmad
然后我通过以下方式为conda安装了pip:
(libmad) bdauser@testsuselinux:~> conda install pip
然后我使用pip for conda成功安装了一个软件包:
(libmad) bdauser@testsuselinux:~> /home/bdauser/anaconda3/envs/libmad/bin/pip install nltk==3.4
我已检查软件包是否通过以下方式实际安装:
(libmad) bdauser@testsuselinux:~/anaconda3/envs/libmad/bin> /home/bdauser/anaconda3/envs/libmad/bin/pip install nltk==3.4
Requirement already satisfied: nltk==3.4 in /home/bdauser/anaconda3/envs/libmad/lib/python3.5/site-packages (3.4)
Requirement already satisfied: six in /home/bdauser/anaconda3/envs/libmad/lib/python3.5/site-packages (from nltk==3.4) (1.12.0)
Requirement already satisfied: singledispatch in /home/bdauser/anaconda3/envs/libmad/lib/python3.5/site-packages (from nltk==3.4) (3.4.0.3)
这时我已经尝试导出conda env:
(libmad) bdauser@testsuselinux:~/anaconda3/envs/libmad/bin> conda env export
name: libmad
channels:
- defaults
dependencies:
- ca-certificates=2019.1.23=0
- certifi=2018.8.24=py35_1
- libedit=3.1.20181209=hc058e9b_0

- ncurses=6.1=he6710b0_1
- openssl=1.0.2r=h7b6447c_0
- pip=10.0.1=py35_0
- python=3.5.6=hc3d631a_0
- readline=7.0=h7b6447c_5
- setuptools=40.2.0=py35_0
- sqlite=3.28.0=h7b6447c_0
- tk=8.6.8=hbc83047_0
- wheel=0.31.1=py35_0
- xz=5.2.4=h14c3975_4
- zlib=1.2.11=h7b6447c_3
prefix: /home/bdauser/anaconda3/envs/libmad
但是nltk并没有显示。
我尝试运行一个简单的conda list
,并且可以看到nltk软件包:
(libmad) bdauser@testsuselinux:~/anaconda3/envs/libmad/bin> conda list
# packages in environment at /home/bdauser/anaconda3/envs/libmad:
#
ca-certificates 2019.1.23 0

libffi 3.2.1 hd88cf55_4
libgcc-ng 8.2.0 hdf63c60_1
libstdcxx-ng 8.2.0 hdf63c60_1
ncurses 6.1 he6710b0_1
nltk 3.4 <pip>
openssl 1.0.2r h7b6447c_0
pip 10.0.1 py35_0
pip 19.1.1 <pip>
python 3.5.6 hc3d631a_0
readline 7.0 h7b6447c_5
setuptools 41.0.1 <pip>
setuptools 40.2.0 py35_0
singledispatch 3.4.0.3 <pip>

wheel 0.31.1 py35_0
xz 5.2.4 h14c3975_4
zlib 1.2.11 h7b6447c_3
如果我对带有export标志的命令运行相同的命令,则不会再看到nltk:
(libmad) bdauser@testsuselinux:~/anaconda3/envs/libmad/bin> conda list --export
# This file may be used to create an environment using:
# $ conda create --name <env> --file <this file>
# platform: linux-64
ca-certificates=2019.1.23=0
certifi=2018.8.24=py35_1
libedit=3.1.20181209=hc058e9b_0
libffi=3.2.1=hd88cf55_4
libgcc-ng=8.2.0=hdf63c60_1
libstdcxx-ng=8.2.0=hdf63c60_1
ncurses=6.1=he6710b0_1
openssl=1.0.2r=h7b6447c_0
pip=10.0.1=py35_0
python=3.5.6=hc3d631a_0
readline=7.0=h7b6447c_5
setuptools=40.2.0=py35_0
sqlite=3.28.0=h7b6447c_0
tk=8.6.8=hbc83047_0
wheel=0.31.1=py35_0
xz=5.2.4=h14c3975_4
zlib=1.2.11=h7b6447c_3
有人可以解释这种行为吗?我在这里做错了什么?目标是将conda env导出到另一台计算机,其中所有软件包都通过pip安装。
预先感谢, 阿莱西奥
答案 0 :(得分:2)
我怀疑问题是您通过PyPI更新了pip
,然后用它来安装您的软件包。我认为Conda在识别未通过Conda安装的pip安装的软件包时遇到问题。相反,请尝试仅使用通过Conda安装的pip
:
conda create -n libmad python=3.5 pip
conda activate libmad
pip install nltk==3.4
提示:如果您处于激活的环境中,则不必提供指向pip
的完整路径。
从技术上讲,我们不必在创建步骤中包含pip
,因为只要安装了pip
,Conda就会始终安装python
。我们会把它留在这里以备不时之需。另请注意,您可以通过Conda Forge渠道获得pip
的较新版本(Python 3.5最高为18.0)。
然后,conda env export
给出:

- defaults
