 The following command will install the latest version of a module and its

 It's also possible to specify an exact or minimum version directly on the
 command line::
 
-    pip install SomePackage==1.0.4    # specific version
-    pip install 'SomePackage>=1.0.4'  # minimum version
+    python -m pip install SomePackage==1.0.4    # specific version
+    python -m pip install 'SomePackage>=1.0.4'  # minimum version
 
 Normally, if a suitable module is already installed, attempting to install
 it again will have no effect. Upgrading existing modules must be requested
 explicitly::
 
-    pip install --upgrade SomePackage
+    python -m pip install --upgrade SomePackage
