总而言之,我仅安装pip创建并激活一个conda环境。然后,我列出了环境中的pip软件包,并安装了所有全局软件包。我检查了pip指向的位置,并正确指向了新创建的环境。那么为什么要列出我的全局软件包?此外,我确认可以加载软件包。任何帮助深表感谢!您可以在zsh提示符下看到我在这里运行的所有代码:
res = q[0];
for(j=1; j*du < h; j++) { res += q[j]; }
res *= pow(du, K);
如您所见,➜ ~ git:(master) ✗ conda create -n pip_test_env pip

(pip_test_env) ➜ ~ git:(master) ✗ pip --version
pip 18.0 from /Users/ethankeller/.local/lib/python3.6/site-packages/pip (python 3.6)
和which pip
显示两个不同的位置。为什么?如何使用正确的(环境)pip包?
答案 0 :(得分:1)
您已经回答了自己的问题。
仔细查看:
(pip_test_env) ➜ ~ git:(master) ✗ which pip
/Users/ethankeller/miniconda3/envs/pip_test_env/bin/pip
(pip_test_env) ➜ ~ git:(master) ✗ pip --version
pip 18.0 from /Users/ethankeller/.local/lib/python3.6/site-packages/pip (python 3.6)
它正在从conda环境中拾取pip可执行文件,但是pip本身是从~/.local/lib/python3.6/site-packages/pip
拾取其内部信息
对此问题有很多引用:
直到有正式的解决方案,您可以执行以下任一操作:
echo "include-system-site-packages=false" >> $CONDA_PREFIX/pyvenv.cfg
OR:
export PYTHONNOUSERSITE=1
