我已经开始使用Mac来安装Python软件包，就像在工作Windows PC时一样。但是在Mac上，我在写入日志文件或站点程序包时经常遇到权限被拒绝的错误。

因此，我考虑过pip install <package>在sudosudo 下运行，但是考虑到我只是想将其安装在当前用户帐户下，是否安全/可接受地使用sudo？

日志文件I / O错误的示例回溯：

Command /usr/bin/python -c "import setuptools;__file__='/Users/markwalker/build/pycrypto/setup.py';exec(compile(open(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --single-version-externally-managed --record /var/folders/tq/hy1fz_4j27v6rstzzw4vymnr0000gp/T/pip-k6f2FU-record/install-record.txt failed with error code 1 in /Users/markwalker/build/pycrypto

更新 这可能取决于权限，但是最好的方法是为你的python项目使用虚拟环境。sudo pip除非绝对必要，否则应避免运行。
