Pip is recommended installer.You need to make sure you have pip available.You can test this by running:
python3 -m pip --version
Installing from PyPI
The most common usage of pip is to install from the Python Package Index.
To install the latest version of "Some Project" on your computer:
python3 -m pip install "SomeProject"
To install a specific version, install the following :
python3 -m pip install "SomeProject==1.4"
To install more than or equal to one version and less than another :
python3 -m pip install "SomeProject>=1,<2"
To install a version that is compatible with a certain version.In this case, this means to install any version of the “1.4.4” version that’s also “4.2”.
python3 -m pip install "SomeProject~=1.4.2"
Requirements files
Put a list of requirements in a requirements file.
python3 -m pip install -r requirements.txt
Installing from VCS
VCS will install a project from VCS in "editable".
python3 -m pip install -e git+https://git.repo/some_pkg.git#egg=SomeProject # from git
python3 -m pip install -e hg+https://hg.repo/some_pkg#egg=SomeProject # from mercurial
python3 -m pip install -e svn+svn://svn.repo/some_pkg/trunk/#egg=SomeProject # from svn
python3 -m pip install -e git+https://git.repo/some_pkg.git@feature#egg=SomeProject # from a branch
Installing from other Indexes
python3 -m pip install --index-url http://my.package.repo/simple/ SomeProject
In addition to PyPI , search an additional index during installation.
python3 -m pip install --extra-index-url http://my.package.repo/simple SomeProject
Installing from a local src tree
Installing from local src in Development Mode, i.e. in such a way that the project appears to be installed, but yet is still editable from the tree of origin.
python3 -m pip install -e <path>
You can install normally from src.
python3 -m pip install <path>
Installing from local archives
python3 -m pip install ./downloads/SomeProject-1.0.4.tar.gz
python3 -m pip install --no-index --find-links=file:///local/dir/ SomeProject
python3 -m pip install --no-index --find-links=/local/dir/ SomeProject
python3 -m pip install --no-index --find-links=relative/dir/ SomeProject
Installing from other sources
To install from other data sources (for example Amazon S3 storage) you can create a helper application that presents the data in a PEP 503 compliant index format.
./s3helper --port=7777
python -m pip install --extra-index-url http://localhost:7777 SomeProject
Installing “Extras”
Extras are optional “variants” of a package. They may include additional dependencies. They enable additional functionality from the package.If you wish to install an extra for a package which you know publishes one:
python3 -m pip install SomePackage[PDF]
python3 -m pip install SomePackage[PDF]==3.0
python3 -m pip install -e .[PDF] # editable project in current directory
