我發現我的系統里有3個版本的pip,如下
pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)
root@Wireless:~/flasky# pip3 -V
pip 9.0.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)
root@Wireless:~/flasky# pip2 -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
我嘗試過升級pip,但最后那個pip8.1無法升級到pip9,好像最高版本就是pip8,我
試過用以下命令進行升級:
pip install -U pip
pip install -U pip2
pip install -U pip3
pip2 install -U pip
pip2 install -U pip2
pip2 install -U pip3
pip3 install -U pip
pip3 install -U pip2
pip3 install -U pip3
試試下面這個
virtualenv venv --python=python3.5
首先你得確認該使用哪個版本的
pip
,如有必要可以這樣嘗試安裝
pip3 install virtualenv
,再執行上面的命令。
