【问题描述】：

我正在尝试安装 pubnub 库，但当我执行 pip install pubnub 时出现错误

Compiling support for Intel AES instructions

/usr/bin/ld: cannot find -lpython2.7

这些是我遵循的步骤

curl -O https://bootstrap.pypa.io/get-pip.py
sudo python27 get-pip.py
sudo yum install git
git clone https://github.com/pubnub/python && cd python/python
sudo update-alternatives --config python
sudo yum install python-devel
sudo yum install gcc

谢谢

【解决方案1】：

您需要安装 Python 的头文件。具体操作方式取决于您的操作系统。

在 Debian 或 Ubuntu 上，例如，类似

sudo apt-get install python-dev

应该这样做。

在 Fedora / CentOS / Red Hat 上，试试

sudo yum install python-devel

【讨论】：

感谢克里斯的回复。我已经安装了头文件。它仍然给我错误。我正在使用 AWS AMI。
@upagna，你是如何安装标题的？
我做了 sudo yum install python-devel 。更新我到目前为止所做的问题
@upagna，你机器上的默认 Python 是什么？（试试python --version。）它也是通过yum 安装的吗？
机器上的默认是2.6，我更新到了2.7。

【解决方案2】：

解决方案，我必须按照这些步骤操作

ld -lpython2.7 --verbose

attempt to open /usr/x86_64-amazon-linux/lib64/libpython2.7.a failed

attempt to open /usr/lib/libpython2.7.so failed
attempt to open /usr/lib/libpython2.7.a failed

检查 python 的 ldconfig 软链接并找出它指向的内容

ldconfig -p | grep python2.7

libpython2.7.so.1.0 (libc6,x86-64) => /usr/lib64/libpython2.7.so.1.0

这表明它正在寻找错误的软链接，我这样更改了软链接

sudo ln -s /usr/lib64/libpython2.7.so.1.0 /usr/lib64/libpython2.7.so

然后不得不像这样运行 pip

sudo /usr/local/bin/pip install pubnub -- Location of pip installed

效果不错
