Ubuntu18.04被我(一个noob)使用,在我了解到虚拟环境的好处之前,他在所有地方都安装了pip包。my.bash rc文件包含:
#setup for python
export PYTHONPATH=/home/stefan/.local/
export PYTHONPATH=/usr/local${PYTHONPATH:+:${PYTHONPATH}}
export PYTHONPATH=/home/stefan/caffe/python:$PYTHONPATH
LD_LIBRARY_PATH=/usr/local/lib${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
不管怎样,因为我一直忘了哪些虚拟环境有哪些包,所以我决定使用pip安装——像这样的用户:
pip install plumbum --user
哪个给了
~/.local/lib/python3.6/site-packages$ ls
plumbum plumbum-1.6.7.dist-info
同时
~/.local/lib/python2.7/site-packages$ ls

不用说,我不能使用从蟒蛇2提示铅。我只使用pip安装,所以我

所以我不知道为什么PIP安装决定把铅放在3.6而不是2.7。有人能启发我吗?(也许给我一个如何清理我的烂摊子的提示)。
我怀疑这与我的Linux总是使用PIP3有关
~/.local/lib/python3.6/site-packages$ pip3 --version
pip 19.0.3 from /usr/local/lib/python3.6/dist-packages/pip (python 3.6)
~/.local/lib/python3.6/site-packages$ pip --version
pip 19.0.3 from /usr/local/lib/python3.6/dist-packages/pip (python 3.6)
~/.local/lib/python2.7/site-packages$ pip --version
pip 19.0.3 from /usr/local/lib/python3.6/dist-packages/pip (python 3.6)
~/.local/lib/python2.7/site-packages$ pip3 --version
pip 19.0.3 from /usr/local/lib/python3.6/dist-packages/pip (python 3.6)
我知道我的/usr/bin中有一个pip2,但是Linux不喜欢它。
/usr/bin$ pip2 --version
Traceback (most recent call last):
File "/usr/bin/pip2", line 9, in <module>
from pip import main
ImportError: cannot import name main
