Which directory should I install Node.js in manually?

Node.js is a popular JavaScript runtime environment that can develop web applications, command line tools, etc. on the server side. Before starting development with Node.js, you need to install it. There are many ways to install Node.js, the most common of which is to install through the official installer. But sometimes, due to network environment and other factors, we may need to install Node.js manually. The manual installation process is more complicated and requires some skills. One of the important questions is: Which directory should I put Node.js in when manually installing it?

The answer is: Different operating systems have different recommended installation paths. Let’s take a look at them separately.

Under Linux or Unix systems, the recommended installation path is /usr/local. The programs in this directory are system-level and can be accessed by all users. This directory is usually created by the root user, so different users need to have permission to access this directory to operate and use the programs in it. Most Linux or Unix systems will have the /usr/local/bin directory, which stores soft links to executable files. Therefore, when installing Node.js, it is recommended to copy its binaries (node ​​or nodejs) to the /usr/local/bin directory and copy the settings files (such as npm) to the /usr/local/lib/node_modules directory . This way, Node.js and npm will be accessible to all users (not just the current user).

In Windows systems, the recommended installation path is C:Program Files or C:Program Files (x86). The programs in this directory are user-level and can only be accessed by the current user. Of course, if you have administrator rights, the installed Node.js will also be accessible to other users. When installing Node.js, you can choose to install it in the C:Program Files or C:Program Files (x86)Node.js directory. In this way, the Node.js binaries will be placed in this directory, and the Node.js commands and npm tools can also be accessed by adding this directory to the PATH environment variable.

It must be pointed out that the above recommended installation paths are for reference only. In fact, you can install Node.js into any directory you like. However, it is worth noting that when installing Node.js, you must ensure that the directory where it is located is in the system's PATH environment variable. This is because the Node.js binaries can only be found in the directories listed in the PATH environment variable, and the Node.js and npm commands can be used from the command line.

Finally, I need to remind everyone that before installing Node.js, you must ensure that the system has installed the required dependency libraries. For example, under a Linux system, installing Node.js requires relying on tools such as python, make, and g. If these tools are not installed, various problems will occur during the Node.js compilation process. Therefore, before manually installing Node.js, it is best to check whether the system has the necessary dependent libraries and install them.

In short, manually installing Node.js requires mastering some skills. One of the important issues is the selection of the installation path. Depending on the operating system, we need to choose different installation paths. It is recommended to install Node.js to the /usr/local or C:Program Files directory, and add the directory where Node.js is located to the PATH environment variable. In addition, before installing Node.js, be sure to check whether the system has installed the necessary dependency libraries.
