我正在尝试在unix上安装3.4 python和pip3。然而，似乎pip3安装在3.2。
当我运行Python3 --version时，它返回
Python 3.4.1
然而，当我运行pip3 --version
时pip 6.0.8 from /usr/local/lib/python3.2/dist-packages/pip-6.0.8-py3.2.egg (python 3.2)
然后我通过编辑这个来尝试在python 3.4上指向pip3：
nano /usr/bin/pip3
然后插入
#!/usr/bin/python3.4
因此，当我在此之后尝试安装请求时，它说它总是安装在3.2上。但是我想在3.4
上运行pip3 install requests
返回
Requirement already satisfied (use --upgrade to upgrade): requests in /usr/local/lib/python3.2/dist-packages
我怎样才能指出3.4而不是3.2？
