错误的解释器：权限被拒绝

Question

我无法安装psycopg2。我尝试将数据库从sqlite更改为postgesql，但始终得到相同的错误。我也尝试通过项目解释器而不是终端安装它，但是得到了：

python setup.py build_ext --pg-config /path/to/pg_config build ...

or with the pg_config option in 'setup.cfg'.

If you prefer to avoid building psycopg2 from source, please install the PyPI
'psycopg2-binary' package instead.

(venv) localhost:mysite Sergio$ pip install psycopg2
bash: /Users/Sergio/PycharmProjects/#WE_GRAPPLE/venv/bin/pip: /Users/Sergio/PycharmProjects/#WE_GRAPPLE/venv/bin/python: bad interpreter: Permission denied
(venv) localhost:mysite Sergio$

Answer 1

请确保您具有pip权限，您可以更改为root

su root 

输入您的root密码，然后

pip install psycopg2
