“Win +R”打開cmd終端，如果直接在里面使用pip命令的時候，要么出現“syntax invalid”，要么出現：

'pip' is not recognized as an internal or external command, operable program or batch file.

此時需要將C:\Python27\Scripts添加到系統環境變量，我順便將C:\Python27\python.exe也添加進了系統環境變量，要保證echo %PATH%能看到對應的目錄。

再使用pip install pyserial就可以安裝serial模塊了，不過我的右如下提示，說我的版本過舊：

C:\Users\h144197>pip install pyserial Requirement already satisfied (use --upgrade to upgrade): pyserial in c:\python27\lib\site-packages You are using pip version 8.1.1, however version 9.0.1 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command.

照著提示做就好了，類似于linux下的shell。

C:\Users\h144197>python -m pip install --upgrade pip Collecting pipDownloading pip-9.0.1-py2.py3-none-any.whl (1.3MB)100% |¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€¨€| 1.3MB 80kB/s Installing collected packages: pipFound existing installation: pip 8.1.1Uninstalling pip-8.1.1:Successfully uninstalled pip-8.1.1 Successfully installed pip-9.0.1

現在就可以使用pip安裝模塊了。

爽吧。。。
