Cannot Install pip Packages Globally on macOS: Externally Managed Environment

In this article, we will discuss how to install a package-managed device globally without using Homebrew and when the required dependencies are not available through packages.

Understanding the Issue

Sometimes, you might encounter a situation where you are unable to install a package-managed device globally using the standard methods, such as Homebrew. This could be due to missing dependencies or a preference to avoid installing via Homebrew.

Externally Managed Environment

In such cases, you can opt for an "Externally Managed Environment." This means you will manually download and install the dependencies and the package itself.

Install Dependencies Manually

1. Identify the dependencies required for the package from its documentation or by checking the dependencies mentioned in the package's Gemfile or requirements.txt.

2. Download and install the dependencies using the appropriate package manager for the operating system. For example, if you are using macOS, you can use brew, apt-get, or pip to install the dependencies.

Install the Package Manually

1. Download the package from its official website or a trusted source.

2. Extract the downloaded package if it is in a compressed format (e.g., .zip or .tar.gz).

3. Navigate to the extracted directory and run the installation script or command provided in the package's documentation.

Code Examples

Here's an example of installing a package (let's say my_package) with a specific version (1.2.3) and its dependencies manually on macOS using curl and sh:

# Install dependencies
brew install dep1 dep2 dep3

# Download my_package
curl -LO https://example.com/my_package-1.2.3.tar.gz

# Extract my_package
tar -xzf my_package-1.2.3.tar.gz

# Navigate to my_package directory
cd my_package-1.2.3

# Install my_package
sh install.sh

Summary

In this article, we have discussed how to install a package-managed device globally without using Homebrew when the required dependencies are not available through packages. We have covered the concept of an "Externally Managed Environment" and provided steps to install dependencies and the package manually. We have also included a code example demonstrating the process on macOS.
