Python可以找到一个模块……然后它可以'；T

我终于开始全力以赴地学习Python了，但由于某种原因，我遇到了一个问题，Python可以在交互式CLI中找到一个模块，而在我编写脚本时却找不到。该模块特别是位于/Library/Python/2.7/site-packages中的mysql.connector。从interactive CLI会话中可以看到，它可以很好地导入mysql.connector。回显sys.path显示“Library/Python/2.7/site包”

这是一个新的CLI窗口（我使用的是Mac 10.10）。注意：最初当我登录时，我会弹出我的home目录，这当然是正常的

所以我只是换了一个目录

cd /Users/wilkie/Projects/dataparse

就这样。。。它找不到mysql.connector

我被官方难住了，不知道为什么会发生这种情况。有人遇到过这种情况吗？

您的主目录或新目录中都有一个

mysql

之类的东西。它可能是

.py

文件，也可能是实际的包（位于错误的位置；）。解决了这个问题，您的问题就会消失。

在回溯中，我看到您将文件命名为

mysql.py

。因此，当您尝试从

mysql.py

导入某些内容时，解释器会在您自己的脚本中查找它，而不是在“实际”模块中。它没有撒下更大的网，而是立即放弃。要解决此问题，请将脚本重命名为不掩盖任何模块名称的名称。
