我创建了一个虚拟环境,安装了熊猫,并尝试将其导入:
$ pip install pandas ...
...
Installing collected packages: numpy, pandas...
$ find $VIRTUAL_ENV -name pandas
/home/sds/.virtualenvs/myenv/lib64/python3.6/dist-packages/pandas
$ python -c 'import pandas'
Traceback (most recent call last):
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'pandas'
$ python --version
Python 3.6.5
$ pip --version
pip 10.0.1 from /home/sds/.virtualenvs/myenv/local/lib/python3.6/dist-packages/pip (python 3.6)
$ wh python
python is /home/sds/.virtualenvs/myenv/bin/python
$ wh pip
pip is /home/sds/.virtualenvs/myenv/bin/pip
我注意到的一个怪异现象是:
$ ls /home/sds/.virtualenvs/myenv/lib*/python3.6/site-packages/
/home/sds/.virtualenvs/myenv/lib/python3.6/site-packages/:
total 0
/home/sds/.virtualenvs/myenv/lib64/python3.6/site-packages/:
total 0
我在做什么错了?
“解决方法”是:
cd $VIRTUAL_ENV/myenv
for d in lib lib64; do
cd $d/python3.6
rmdir -v site-packages && mv -v dist-packages site-packages
cd ../..
done
很明显,出了点问题...
PS。 virtualenv设置:
pip3 install --user virtualenv virtualenvwrapper
pip3 install --user --upgrade virtualenv virtualenvwrapper
mkvirtualenv -p python3 myenv
答案 0 :(得分:0)
我只能猜测您正在使用哪个系统。我发现在Mac上,我必须对要与python 3.6。*一起使用的软件包使用pip3 install ...
