Question

我的pyhton2.7安装在/ usr / local / lib中。如果我输入which python2.7，我可以/usr/local/bin/python2.7。然后我将〜/ .bashrc中的PYTHONPATH设置为

export PYTHONPATH="/usr/local/bin/python2.7:$PYTHONPATH"

我喜欢安装pip和虚拟环境。然后尝试了

sudo apt-get install python-pip python-dev python-virtualenv

我遇到错误，仍然在/usr/lib中寻找python。错误是

如何正确设置python路径？

编辑：我的回音$ PATH给了

/usr/local/bin:/usr/local/cuda-8.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/bin/python2.7

echo $ PYTHONPATH给了

/home/coie/Softwares/apollocaffe/python:/usr/local/bin/python2.7:

Answer 1

我使用/usr/local删除了>sudo rm -rf /usr/local/lib/python* or libpython*中安装的所有python。 bin和share文件夹中的那些也被清理。然后由于所有程序都在/usr内查找python，安装路径设置为sudo ./configure --prefix = /usr

根据https://askubuntu.com/a/250935/610294：

尝试附加到PYTHONPATH而不是完全覆盖它。

阅读：用以下内容替换你添加到bashrc的行：

export PYTHONPATH=$PYTHONPATH:/usr/local/bin/python2.7
