python matplotlib pip安裝亞馬遜EC2

Question

我正在嘗試在我的ubuntu aws ec2實例上安裝matplotlib：

sudo pip install matplotlib

我確實安裝了這些：

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

我仍然收到此錯誤：

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

Answer 1

你需要：

sudo apt-get install gcc

Answer 2

檢查錯誤的第一行，其中明確指出：

目錄“ /home/ubuntu/.cache/pip/http”或其父目錄不屬於當前用戶，並且緩存已被禁用。 請檢查該目錄的權限和所有者。 如果使用sudo執行pip，則可能需要sudo的-H標志。

因此，請嘗試：

sudo -H pip install matplotlib

還要檢查是否已安裝setuptools。
