没有名为pip的模块

操作系统:Mac OS X 10.7.5 Python版本:2.7.5

我已经从https://pypi.python.org/pypi/setuptools用ez_setup.py安装了setuptools 1.0 然后我从https://pypi.python.org/pypi/pip/1.4.1下载pip.1.4.1 pkg。

在iTerm中运行(sudo) python setup.py install即可显示

然后我输入pip install，错误信息是这样的

Traceback (most recent call last):   File

谁以前遇到过同样的问题，能给我一些解决方法吗?

当前回答

我只需要用pip3替换pip，所以我最终运行如下命令

其他回答

对于python2.7，请从https://bootstrap.pypa.io/pip/2.7/get-pip.py下载

然后运行

python get-pip.py

我在MacOS Big Sur上使用Python 3.8.6时遇到了同样的错误。

无论我使用pip还是pip3，我都会得到这个错误:

 File "/Users/marcelloromani/dev/<repository>/venv/bin/pip", line 5, in <module>
    from pip._internal.cli.main import main
ModuleNotFoundError: No module named 'pip'

原来我的virtualenv已经过时了。这解决了我的问题:

删除旧的virtualenv

$ deactivate
$ rm -rf venv

初始化一个新的virtualenv

$ virtualenv venv
$ . venv/bin/activate

安装新的要求，然后工作:

$ pip install -r src/requirements.txt

试着重新安装pip 使用curl命令下载get-pip.py文件:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

如果curl不起作用，那么打开这个链接: get-pip.py

在您的目录中创建get-pip.py文件从该链接复制代码，并将其放入get-pip.py文件中，并将该文件保存在同一目录中。然后运行命令

python get-pip.py

在Mac上使用brew是一个更好的选择，因为apt-get不可用。命令:

brew install python

如果你的机器上同时安装了python2和python3

python2.7 -m ensurepip --default-pip

应该简单地解决这个问题。

如果相反，你从python3中缺少pip，那么只需在上面的命令中将python2.7更改为python3。
