Python使用pip安装pySerial串口通讯模块
pySerial封装了对串口的访问,供大家参考,具体内容如下 特性 在支持的平台上有统一的接口。 有关Python的环境配置请参考: 《Python入门》Windows 7下Python Web开发环境搭建笔记 而 pip 是随 Python 一同安装的,如下图: pip 帮助信息,在命令行中输入 pip 就能看到以下的帮助信息 G:&;pip Usage: pip <command> [options] Commands: install Install packages. uninstall Uninstall packages. freeze Output installed packages in requirements format. list List installed packages. show Show information about installed packages. search Search PyPI for packages. wheel Build wheels from your requirements. help Show help for commands. General Options: -h,--help Show help. --isolated Run pip in an isolated mode,ignoring environment variables and user configuration. -v,--verbose Give more output. Option is additive,and can be used up to 3 times. -V,--version Show version and exit. -q,--quiet Give less output. --log <path> Path to a verbose appending log. --proxy <proxy> Specify a proxy in the form [user:passwd@]proxy.server:port. --retries <retries> Maximum number of retries each connection should attempt (default 5 times). --timeout <sec> Set the socket timeout (default 15 seconds). --exists-action <action> Default action when a path already exists: (s)witch,(i)gnore,(w)ipe,(b)ackup. --trusted-host <hostname> Mark this host as trusted,even though it does not have valid or any HTTPS. --cert <path> Path to alternate CA bundle. --client-cert <path> Path to SSL client certificate,a single file containing the private key and the certificate in PEM format. --cache-dir <dir> Store the cache data in <dir>. --no-cache-dir Disable the cache. --disable-pip-version-check Don't periodically check PyPI to determine whether a new version of pip is available for download. Implied with --no-index. 安装 pySerial 串口通讯模块 使用 pip 来安装非常简单,只需使用以下命令:pip install pyserial。 安装时可能会出现以下提示: 可以按照提示执行升级 pip:pip install --upgrade pip 也可以不升级 pip,我上面的图是已经安装过了。没有安装的话会如下图显示: 有时候会出现类似下图的网络错误: 重新执行一遍就可以了 卸载可使用命令:pip uninstall pyserial 以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持编程小技巧。 您可能感兴趣的文章:
