如何設置python安裝路徑？

我的pyhton2.7安裝在/ usr/local/lib中。如果我輸入which python2.7，我可以有/usr/local/bin/python2.7。後來我設定在〜/ .bashrc PYTHONPATH作爲如何設置python安裝路徑？

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

我喜歡安裝PIP和虛擬環境。然後嘗試作爲

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

我有錯誤，還在/usr/lib尋找蟒蛇。錯誤是

如何正確設置python路徑？

編輯：我回聲$ PATH給

/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

回聲$ PYTHONPATH給

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

只是驗證，你的意思是'〜/ .bashrc'而不是'〜/ bashrc'，對吧？ –

對不起〜/ .bashrc – batuman

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

嘗試，而不是附加到PYTHONPATH完全覆蓋它。

閱讀：更換你行你加入這.bashrc中：

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

是的，我把路徑放在 – batuman

在我鏈接的評論中，那個線程還提到了腳本文件夾。你嘗試過嗎？（'export PYTHONPATH = $ PYTHONPATH：/ usr/local/bin/python2.7/Scripts'） –

鍵入setenv PATH 「$ PATH：在/ usr/local/bin目錄/蟒蛇」，然後按Enter。或鍵入export ATH =「$ PATH：/ usr/local/bin/python」，然後按Enter鍵。

我試過並把它放在編輯中。 – batuman

我使用>sudo rm -rf /usr/local/lib/python* or libpython*刪除了安裝在/usr/local中的所有python。那些在bin和共享文件夾中的文件也被清除。然後，因爲所有的程序在/usr裏尋找python，所以安裝路徑設置爲sudo ./configure --prefix = /usr
