Ⅰ、Scenario Description

Encountering the error message "The operation was rejected by your operating system" usually means that the permission settings of the operating system prevent npm from performing certain operations, such as file or directory writing. This issue may be caused by various reasons, and the following are some common troubleshooting steps:

Ⅱ、Solutions

(Ⅰ) Run Command Line as Administrator

Ensure that you are running the command-line tool with administrator privileges. On Windows, you can right-click the Command Prompt or PowerShell icon and select "Run as administrator".

(Ⅱ) Clear npm Cache

Sometimes, issues in the npm cache can cause installation failures. Try clearing the npm cache:

npm cache clean –force

Then try installing again:

npm install

(Ⅲ) Check Disk Space

Ensure that there is sufficient space on your disk to install new packages and their dependencies.

(Ⅳ) Modify npm Configuration

If unsafe-perm or _authToken is set in your npm configuration, it may affect the installation. Try changing npm's configuration to disable unsafe-perm:

npm config set unsafe-perm false

(Ⅴ) Check Firewall and Antivirus Software

Certain firewalls or antivirus software may block npm's network requests or file writing operations. Check the settings of these security software to ensure they do not prevent npm from functioning normally.

(Ⅵ) Repair npm

Sometimes, issues with npm itself can cause installation failures. Try reinstalling Node.js and npm, or use nvm (Node Version Manager) to manage multiple Node.js versions.

(Ⅶ) Check File or Directory Permissions

If the error message mentions specific files or directories, check the permission settings of these files or directories. You may need to modify the permissions or move the project to another location to obtain sufficient permissions.

(Ⅷ) Update Node.js and npm

Ensure that you are using the latest versions of Node.js and npm. Older versions may contain known bugs or compatibility issues.

(Ⅸ) Check npm Logs

View npm's log files, which can help you find more detailed error information. The location of the log files can be queried using the following command:

npm config get cache

The log files are typically located in the .npm/_logs directory.

(Ⅹ) Configure the .npmrc File in the Folder as Follows
