我在导入 PyDictionary 库时遇到问题
I am having a trouble importing the PyDictionary library
基本上,我使用 pip install PyDictionary
下载了这个库,我通过再次编写相同的东西来确保它存在并且出现了:
Requirement already satisfied: PyDictionary in c:\users\ziad\appdata\local\programs\python\python39\lib\site-packages (2.0.1)
Requirement already satisfied: bs4 in c:\users\ziad\appdata\local\programs\python\python39\lib\site-packages (from PyDictionary) (0.0.1)

然而,当我尝试在 atom 中 运行 这个简单的程序时,它说找不到模块。
这是程序:
from PyDictionary import PyDictionary
dictionary = PyDictionary()
print (dictionary.meaning("indentation"))
这是错误:
Traceback (most recent call last):
File "C:\Users\Ziad\Desktop\programs\Dictionary.py", line 1, in <module>
from PyDictionary import PyDictionary
ModuleNotFoundError: No module named 'PyDictionary'
我发现正确执行程序的唯一方法是将文件移动到库所在的文件夹,以便 atom 可以找到库。奇怪的是图书馆 numpy 工作得很好。
我真的很想知道这个问题的答案。
您遇到的问题是您的 pip
命令未连接到您安装的 python3
。
如果您正在使用 Windows,那么您应该有一个“python 启动器”,您可以使用它来仔细检查您安装的 Python 版本,如下所示:
PS C:\> py -0
Installed Pythons found by C:\windows\py.exe Launcher for Windows
-3.9-64 *
-3.7-32
在这里你可以看到我的设备上安装了两个版本的Python。那么,让我们使用它们自己的 pip
.
版本检查这两个安装都安装了什么
让我们从我的 3.7
安装开始:
PS C:\> py -3.7 -m pip list
Package Version
------------------ ---------
beautifulsoup4 4.8.1
Jinja2 2.11.2
keyring 21.2.0
这里可以看到我安装了三个包
现在让我们检查一下我的 3.9
安装:
PS C:\> py -3.9 -m pip list
Package Version
-------------------------------- ---------
matplotlib 3.4.1
numpy 1.19.4
pandas 1.1.5
pip 21.0.1
我在上面所做的基本上是调用不同的 python
安装,并使用以下标志打开它:
-m mod : run library module as a script (terminates option list)
pip
命令基本上只是 <python-installation> -m pip
的别名,所以当我发出上述命令时,我启动了 pip
和特定的 python-安装.
如果您没有上述示例中的“python-launcher”,但您的 python-interpreter 有不同的别名,那么您可以发出相同的命令以同样的方式,只需使用您的别名。
这里有几个例子:
# will show you the installed packages for the alias "python2"
python2 -m pip list
# will show you the installed packages for the alias "python3"
python3 -m pip list
你显然可以使用相同的逻辑向 pip
发出其他命令,所以如果你想安装特定版本的包,你可以这样做:
# will try to install the given package for the alias "python3"
python3 -m pip install <nameOfPackage>
输入这个
python -m pip install --upgrade pip setuptools wheel
确保包含空格。
那么:
C:/Python36/Scripts/pip install Pydictionary
备注:
您正在为特定 python 版本安装 PyDictionary 以查看您在终端上安装的 python 版本,键入 py 并按回车
然后在 Python36 上输入你的版本...确保你在名称 Python 上使用大写字母,脚本...我遇到了同样的问题,我安装了 python27 版本.
