python - pip 轮和覆盖范围 : command not found error

Question

我想在我的 Linux 服务器上使用轮子，因为它看起来更快，但是当我这样做时:

pip install wheel    
pip wheel -r requirements_dev.txt

其中包含以下软件包

nose
django_coverage
coverage

我得到覆盖:找不到命令，就像没有安装一样。

如果找不到用于 pip install 的轮子或者我没有正确理解/设置它，是否有后备？

Answer 1

你能试试这个吗？

virtualenv venv
source venv/bin/activate
pip -r install requirement.txt

也可以使用轮子来实现:-

pip wheel -r check.txt
Collecting nose (from -r check.txt (line 1))
  Using cached nose-1.3.7-py2-none-any.whl
  Saved ./nose-1.3.7-py2-none-any.whl
Collecting django_coverage (from -r check.txt (line 2))
  Saved ./django_coverage-1.2.4-cp27-none-any.whl
Collecting coverage (from -r check.txt (line 3))
  Using cached coverage-4.2-cp27-cp27m-macosx_10_10_x86_64.whl
  Saved ./coverage-4.2-cp27-cp27m-macosx_10_10_x86_64.whl
Skipping nose, due to already being wheel.
Skipping django-coverage, due to already being wheel.
