PyInstaller belongs to a third-party library: use Additional installation is required before
-installing a third-party library requires the pip tool to install
pyinstallererthe third-party library that needs to be run, so it cannot be installed in the IDLE environment. It
needs to be installed on the comand command line under the windows platform,
such as the Linux/Mac OS X platform. Corresponding command line to execute pip instructions
to install third-party libraries through instructions
pip install pyinstaller
If the windows system only has one python installed, then
execute this one (if the network speed is fast enough)
pip install pyinstaller
If the internet speed is not enough, borrow from Qinghuayuan
pip install pyinstaller -i https://pypi.tuna.tsinghua.edu.cn/simple/
When there are several versions of python in the linux system, the
default setting command python is version 2.7 and python3 is version 3.9.
What I execute is
python3 -m pip install pyinstaller -i https://pypi.tuna.tsinghua.edu.cn/simple/
-m
-m Switch to running an appropriate copy of pip
Specify the python version to install a library/package
python -m pip install SomePackage
python3 -m pip install SomePackage
Specify the python version to install a specified version of the library/package
python -m pip install SomePackage==1.0.4 # specific version
python3 -m pip install SomePackage==1.0.4 # specific version
Specify python to install a library/package that is higher than a certain version.
When using comparator operators,
such as >, <or some other special characters interpreted by the shell, the package name and version should be enclosed in double quotes:
python -m pip install "SomePackage>=1.0.4" # minimum version
python3 -m pip install "SomePackage>=1.0.4" # minimum version
An upgrade version of a library / package
to run pip install --upgradethe package to upgrade to the latest version of the
multiple python versions for the input version
python -m pip install --upgrade SomePackage
python3 -m pip install --upgrade SomePackage
When you see this, it still fails to install, or there is an error, then it may be that your python does not have pip installed
. Install the pip installer.
Starting with Python 3.4, it is included in the Python binary installer by default.
When your pip is not installed by default.
The solution is:
python -m ensurepip --default-pip
Display all packages installed in the virtual environment
pip listAll packages installed in the virtual environment will be displayed
pip list
pip show will display information about a specific package (note that this is generally used in a virtual environment and needs to be viewed in the virtual environment)
pip show SomePackage
Uninstall a library/package
pip uninstall
Such as uninstalling you-get
pip uninstall you-get
Pack the installation list into a txt file
pip freezeA similar list of installed packages will be generated
(you need to enter the virtual environment you specify and then package/execute this instruction)
pip freeze > requirements.txt
View the txt file of the packaging result
linux system
cat requirements.txt
In windows system (click to open it)
type requirements.txt
Install the library/package packaged in the txt file
(You need to enter the virtual environment you specify and then package/execute this instruction)
python -m pip install -r requirements.txt
python3 -m pip install -r requirements.txt
