python matplotlib pip安装亚马逊EC2

Question

我正在尝试在我的ubuntu aws ec2实例上安装matplotlib：

sudo pip install matplotlib

我确实安装了这些：

sudo apt-get install libpq-dev python-dev libxml2-dev libxslt1-dev libldap2-dev libsasl2-dev libffi-dev

我仍然收到此错误：

ubuntu@ip-102-21-11-112:~$ sudo pip install matplotlib

Answer 1

你需要：

sudo apt-get install gcc

Answer 2

检查错误的第一行，其中明确指出：

目录“ /home/ubuntu/.cache/pip/http”或其父目录不属于当前用户，并且缓存已被禁用。 请检查该目录的权限和所有者。 如果使用sudo执行pip，则可能需要sudo的-H标志。

因此，请尝试：

sudo -H pip install matplotlib

还要检查是否已安装setuptools。
