安装

MacOS

1. 先安装brewhome, 官网: brewhome(已安装的跳过)
2. 打开终端, 输入命令brew install pypy3(没翻墙的可能比较慢)
3. 安装pypy的pip, 在终端输入curl -O https://bootstrap.pypa.io/get-pip.py && pypy3 get-pip.py

CentOS

待测试...

基本使用

基本命令

• pypy3: 运行脚本, 相当于python3

  • pypy3 xxx.py # 运行脚本xxx.py
  • pypy3 -m pip install xxx # 安装依赖xxx

  • pypy3 -m venv xxx # 创建一个虚拟环境到xxx目录

    • 切换到该虚拟环境: source xxx/bin/activate, 退出虚拟环境: deactivate

• pip_pypy3: 安装依赖库, 相当于 pip3

  • pip_pypy3 install xxx # 安装依赖xxx
  • pip_pypy3 install -r requirement.txt # 递归安装requirement.txt里面的依赖

• easy_install_pypy3: 安装依赖库, 相当于easy_install3

  • easy_install_pypy3 xxx # 安装依赖xxx

测试性能

# test.py
from time import time

times = 10
start_time = time()

for t in range(times):
    sum = 0
    st = time()
    for i in range(10 ** 6):
        sum += i
    print('{}: speed time: {}'.format(t, time()-st))

total_time = time()-start_time
print('speed time avrage: {}, total: {}'.format(total_time / times, total_time))

简单的测试来看, pypy比cpython快了好几倍
