使用 pip install 时生产服务器上的权限被拒绝

Question

我正在尝试在生产服务器上将软件包安装到我的 Django 应用程序中，并且收到权限被拒绝错误。下面是回溯。我已经使用 pip install 安装了其他软件包，它没有给我任何问题，所以我不完全确定我为什么会遇到这个问题。

[humanlink@web526 ~]$ pip install cryptography

我如何找出用户是谁？如果我想将用户设置为我，生产服务器的用户是谁？会是我当前在计算机上登录的用户吗？还是托管我的域的公司 Webfaction 的管理员？

Answer 1

你应该是 root 才能在系统范围内安装，如果你不能，你可以这样做

pip install  --user  cryptography

Answer 2

你在谷歌上搜索过这个问题吗？

试试这个： https://community.webfaction.com/questions/16163/getting-permission-denied-trying-to-install-sqlalchemy

或

使用：sudo pip install cryptography。
可能对你有帮助。
