我正在尝试通过 Pip 安装 zipline 模块，但出现异常 [重复]

Question

我正在尝试使用 "pip install zipline" 安装 zipline 模块，但出现此异常：

IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/editor.pyc'`  - any help would be greatly appreciated

Answer 1

因为你不是root。您可以使用 sudo 获取超级用户权限：

sudo pip install zipline

否则

对于 GNU/Linux：

在 Debian 派生的 Linux 发行版上，您可以通过运行以下命令从 apt 获取所有必要的二进制依赖项：

$ sudo apt-get install libatlas-base-dev python-dev gfortran pkg-config libfreetype6-dev

在最近从 RHEL 派生的 Linux 发行版（例如 Fedora）上，以下内容应该足以获得必要的附加依赖项：

$ sudo dnf install atlas-devel gcc-c++ gcc-gfortran libgfortran python-devel redhat-rep-config

在 Arch Linux 上，您可以通过 pacman 获取额外的依赖项：

$ pacman -S lapack gcc gcc-fortran pkg-config

还有用于安装 Python 3.4 的 AUR 包（Arch 的默认 python 现在是 3.5，但 Zipline 目前仅支持 3.4）和 ta-lib，一个可选的 Zipline 依赖项。 Python 2 也可以通过以下方式安装：

$ pacman -S python2

Answer 2

避免使用sudo 来安装带有pip 的软件包。请改用--user 选项，或者使用虚拟环境更好。

见this SO answer。我认为这个问题与那个问题重复。
