Python点不能安装任何东西

Question

我正在尝试使用pip安装熊猫。

sudo pip install pandas

我收到以下错误：

➜  ~ which python
/usr/bin/python

➜  ~ python --version
Python 2.7.10

➜  ~ sudo pip install pandas
The directory '/Users/bdisha/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

我究竟做错了什么？

Answer 1

这是由于最近对Python.org网站的TLS弃用。

这个答案有细节。

总而言之，请按以下方式升级点子：

curl https://bootstrap.pypa.io/get-pip.py | python

然后运行：

pip install pandas

Answer 2

我会尝试sudo chown -R your_user_name / Users / bdisha / Library / Caches / pip / http和chown -R your_user_name / Users / bdisha / Library / Caches / pip

Answer 3

pip install -U pip
