我试图在堆栈上搜索相同的问题,但没有一个是有用和准确的。我试着安装python-dateutil。我是单向做的,然后是另一个做法:
1)我从https://pypi.python.org/pypi/python-dateutil/下载了 python-dateutil-2.4.2.tar.gz 并尝试手动安装。我没有解决这个问题,所以我将其解压缩:C \ Python27 \并在PowerShell中执行以下操作:
PS C:\ Python27 \ python-dateutil-2.4.2> python python-dateutil.py
它没有成功,我得到了这个:
PS C:\Python27\python-dateutil-2.4.2> python setup.py
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help
error: no commands supplied
2)我也从https://pypi.python.org/pypi/python-dateutil/下载了 python_dateutil-2.4.2-py2.py3-none-any.whl 。这次当然是轮文件。我把它放在:C \ Python27 \和PowerShell中我做了:
PS C:\ Python27 \ python-dateutil-2.4.2> pip install python_dateutil-2.4.2-py2.py3-none-any.whl
同样,它没有成功,我得到了这个:
The term 'pip' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spellin
g of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:4
+ pip <<<< install python_dateutil-2.4.2-py2.py3-none-any (1).whl

我该怎么办?
答案 0 :(得分:1)
python setup.py install
pip
不在路径中。将C:\Python27\Scripts\
添加到%Path%环境变量中。见How do I install pip on Windows? 答案 1 :(得分:1)
这样做:
1 - 将pip安装目录添加到环境变量PATH
2 - 打开新的命令提示符
3 - 输入pip install python-dateutil
完成!!
