python - 没有名为 'setuptools' 的模块，即使已安装该模块

Question

我正在尝试使用 Windows 通过 pip 安装 openpyxl 软件包。

PS C:\Scripts> pip install openpyxl
Collecting openpyxl
    Using cached openpyxl-2.5.0.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
     File "<string>", line 1, in <module>
    ModuleNotFoundError: No module named 'setuptools'

当我运行 setuptools 安装时，我得到:

PS C:\Scripts> pip install setuptools
>>
Requirement already satisfied: setuptools in c:\scripts\lib\site-packages

我尝试再次卸载并安装setuptools，但没有成功。我做错了什么？

PS C:\Users\dolinar\Desktop\setuptools-38.4.0> python .\easy_install.py
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

[Errno 2] No such file or directory: 'C:Lib\\site-packages\\test-easy-install-9076.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

C:Lib\site-packages\

This directory does not currently exist.  Please create it and try again, or
choose a different installation directory (using the -d or --install-dir
option).

该目录存在。

它应该在系统范围内安装。如果您使用的是 Ubuntu/Debian:

apt-get install -y python-setuptools

如果您使用的是 Windows，请参阅 this answer安装设置工具。
