【问题描述】：

尝试使用 pip3 安装 python-snappy-0.5.4.tar.gz，我在 setup.py 文件中进行了如下更改后重新打包了它。

-                         libraries=['snappy'],
+                         libraries=['csnappy'],

失败的点数

(venv) [root@sl2o2pocxbar301 vchauhan]# pip3 install python-snappy-0.5.4.tar.gz
Processing ./python-snappy-0.5.4.tar.gz
    Complete output from command python setup.py egg_info:

        buffer = _builtin_open(filename, 'rb')
    FileNotFoundError: [Errno 2] No such file or directory: '/tmp/pip-dvxrqtnr-build/setup.py'

You are using pip version 9.0.3, however version 20.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

作为调试过程的一部分，我提取了这些文件，并且收到了这样的消息，

(venv) [root@sl2o2pocxbar301 vchauhan]# tar -xvf python-snappy-0.5.4.tar.g

.tar.gz 文件解压后的内容。

(venv) [root@sl2o2pocxbar301 vchauhan]# cd python-snappy-0.5.4/

【解决方案1】：

您已成功激活您的环境venv

我不明白你为什么使用pip3 install python-snappy-0.5.4.tar.gz

我知道你也想安装python-snappy

也许这会解决你的问题：pip install python-snappy

tar 文件一般执行为：tar -zxvf python-snappy-0.5.4.tar.gz，然后进入解压后的文件夹，执行安装文件。
