python – Virtualenv venv失败,出现以下错误

我是Python开发的新手,我正在尝试在我的项目目录中安装virtualenv.

但是我有以下错误:

我安装了点子

easy_install pip

然后我安装了virtualenv

pip install virtualenv

没有任何错误.但是我还是得到了这个.我不想用sudo试试.我是不是该?

更新:我用sudo安装它们,我摆脱了这个错误.然而另一个尝试使用pip安装时:

air:dashboard alexandrurada$pip install flask

-bash:/usr/local / bin / pip:“path_here”:错误的解释器:没有这样的文件或目录

更新2:之前的错误是由于目录名称中的空格.看起来路径不适用于此类名称.

无论如何,我现在得到的错误是

File "/usr/local/bin/pip", line 7, in <module>
    from pip import main
ImportError: No module named pip

我检查了我的/usr/local / bin / pip,文件存在.

你需要sudo pip install virtualenv来全局安装virtualenv.在设置virtualenvs时,请确保不要使用sudo,并在尝试安装之前激活virtualenv.

[Errno 13]权限被拒绝:表示您没有写入权限.
