安装

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh

sh Miniconda3-latest-Linux-x86_64.sh

一路yes即可安装完成，完成后source ~/.zshrc或者source ~/.bashrc生效。

# shell自动加载
conda config --set auto_activate_base false
# 回滚
conda init --reverse $SHELL

初始化环境

创建环境

conda create --name myenv python=3.11

创建后不是默认生效的，需要执行conda activate myenv生效，如果需要默认生效则需要加入到~/.zshrc中：

echo "conda activate myenv" >>~/.zshrc

删除环境

conda remove --name myenv --all

安装包

conda install package_name

更新包

conda update package_name

查看已安装的package

conda list

更新conda

conda update conda

import time

使用logging模块打印日志的时候遇到错误：

Traceback (most recent call last):
  File "saas_utils.py", line 106, in <module>
    sangfor_login("192.168.10.1", login_user, login_pwd)
  File "saas_utils.py", line 72, in sangfor_login
    logging.INFO("%s: %s" % (type(cookie_str), cookie_str))
TypeError: 'int' object is not callable

网上查了一下，出现这个问题的原因是函数或者变量命名错误了，但是检查了一下没有发现有重复的函数和变量名。

后面仔细推敲了一下才发现函数名字写错了，logging.info被我写成了loggin.INFO，loggin.INFO是日志的调试级别，当成函数使用当然报错了。

一、setuptools安装错误：RuntimeError: Compression requires the (missing) zlib module

1. 描述

搞了个腾讯云的服务器，闲在手上没事准备当个测试机用用，写写代码什么的。然后按照之前写的文章安装了python2.7 ，安装的中途出现了一个错误：
