The inability to load tsc.ps1 is due to the system's script running restrictions

When I was running the tsc command on PowerShell, I encountered an error message that I hadn't seen before.

Now I'm debating whether to adjust the security settings in PowerShell to fix this issue. I found a suggestion here: PowerShell says "execution of scripts is disabled on this system."

Update

I recently learned about npm's new feature to use ps1 scripts, which might be causing this error. The npm community has discussed this here: https://github.com/npm/cli/issues/470

Answer №1

If you want to execute this code in PowerShell, ensure that you do so with administrative privileges:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

Answer №2

Opt for tsc.cmd over tsc. Here's a quick example:

tsc.cmd -v
tsc.cmd --init

Answer №3

Access Command Prompt by pressing: windows + R

Input: Powershell

Next, enter the following:

set-executionpolicy remotesigned

Choose option: A

Answer №4

I encountered a similar issue, but found a simple solution. Try running the command tsc.cmd [filename.ts] to resolve it.

This should solve the problem effortlessly.

Answer №5

In the case of using Visual Studio Code, you have the option to utilize tsc.cmd in place of tsc. This approach proved successful in my experience.

Answer №6

Resolved

Encountering the error message "tsc.ps1 cannot be loaded because running scripts is disabled on this system" typically indicates that the execution policy restricts running a specific script on Windows.

To address this issue, there are three possible solutions:


  1. Resolve the error by using the command
    Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
    .

To implement this solution, launch PowerShell as an administrator and set the execution policy with the Set-ExecutionPolicy command.

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

If executing the command as an admin proves challenging, attempt running it with the CurrentUser parameter.

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Utilize the Get-ExecutionPolicy command to verify the current session's execution policy (RemoteSigned) following any changes made.

Get-ExecutionPolicy
  1. Add .cmd to the command

Appending .cmd to the command instructs PowerShell to utilize the cmd version instead.

tsc.cmd -v

tsc.cmd --init

tsc.cmd myFile.ts
  1. You might also opt for prefixing the tsc command with npx

The npx prefix serves as an npm package runner capable of executing packages from the npm registry without requiring installation.

npx tsc -v

npx tsc --init

npx tsc myFile.ts

Answer №7

To improve your workflow, try using tsc.cmd instead of just tsc

For example:

Prior to change : tsc script.ts && node script.js

After making the change: tsc.cmd script.ts && node script.js

Answer №8

When working in VS Code, opt for tsc.cmd over tsc. Here's an illustration:

tsc.cmd -v

Answer №9

If you're utilizing Powershell as your default shell, you may encounter an error when running a command: as shown here

To resolve this issue, you have several options to choose from:

  1. You need to enable execution policy by entering the following command in Powershell (PS):

    Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

Once it's enabled, you can run the tsc command directly.

  • As Powershell is the default shell terminal, use the following command for all typescript-related commands:

    tsc.cmd -v

  • If you prefer, you can switch your default shell from Powershell to cmd by using Visual Studio Code. With the cmd shell, you can use typescript normally with tsc -v instead of tsc.cmd -v

Steps to set cmd.exe as the default shell for VS Code:

Answer №10

  1. To begin, open your PowerShell as an administrator and check the current execution policy by using the command "get-ExecutionPolicy". It should show as restricted.

  2. Next, enter the command "Set-ExecutionPolicy Unrestricted"

  3. Confirm with a 'yes' for all by typing [A]

Alternatively

  1. Try using "Set-ExecutionPolicy -ExecutionPolicy RemoteSigned"

  2. Verify by running tsc --int

  3. Refer to the steps below for further assistance

After encountering a similar problem, I managed to find a solution by investigating my anti-virus software settings and disabling the auto-container feature. Running the command: tsc.cmd <file.ts>

successfully resolved the issue for me!

Answer №14

To execute TypeScript compiler commands on Windows, use tsc.cmd in place of tsc. For instance:

tsc.cmd -v
tsc.cmd --init

Answer №15

Issue resolved: To address this problem, open PowerShell as an administrator and enter the following command:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

Answer №16

"Troubleshooting: File Cannot Be Loaded Due to Disabled Script Execution in Windows PowerShell." A recent update in Windows permissions has caused this issue, but it can easily be fixed by following these steps:

If you encounter an error stating that your script "cannot be loaded because running scripts is disabled on this system" when trying to run a script in Powershell on Windows 10, you need to adjust the execution policies.

Follow these commands in PowerShell:

1) Get-ExecutionPolicy -List

2) Set-ExecutionPolicy Unrestricted

3) Set-ExecutionPolicy Unrestricted -Force

Note: After entering the 2nd command, you will be prompted to confirm with 'Y' and press Enter.

If you receive the error message that says "File cannot be loaded because running scripts is disabled on this system," it means you must enable script running on your Windows 10 PC. This issue arises when your user account lacks the necessary permissions to execute the script. You do not necessarily need Administrator-level permissions; rather, you need to have unrestricted permissions to run such PowerShell scripts or cmdlets.

Answer №17

When using Visual Studio Code, go to the terminal and open a new terminal window. Look for an arrow pointing downwards next to the plus sign in the right corner of the terminal and select "cmd". You can then run the command tsc filename.ts without needing to type tsc.cmd filename.ts. Finally, use the command node filename to see your output magically appear before your eyes!

Answer №18

To resolve the issue in Visual Studio Code, you can fix it by adding the following code to the setting.json file:

"terminal.integrated.profiles.windows": {
  "PowerShell": {
    "source": "PowerShell",
    "icon": "terminal-powershell",
    "args": ["-ExecutionPolicy", "Bypass"]
  }
},
"terminal.integrated.defaultProfile.windows": "PowerShell",

You can find more information and details about this solution in the following reference link.

Answer №19

Just performing this action alone

Type in Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

You may encounter the following error message

Set-ExecutionPolicy : Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. To modify the execution policy for
the default (LocalMachine) scope, launch Windows PowerShell using the "Run as administrator" option. To alter the execution policy for the current user, execute "Set-ExecutionPolicy
-Scope CurrentUser". At line:1 char:1

  • Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
  •   + FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.SetExecutionPolicyCommand
    
    

Therefore, you need to run windows powershell as an administrator and enter the following command:

Type in Set-ExecutionPolicy -Scope CurrentUser

Then set,

ExecutionPolicy: remotesigned

Proceed by typing A to confirm all changes. Everything will then be resolved. Best of luck!

For those using Windows, I highly suggest installing the latest open-source PowerShell by visiting https://github.com/PowerShell/PowerShell/releases.

This new version resolved all of our issues, such as the problem of disabled script running. We also encountered difficulties with paths when using 'git bash' due to the differences in how backslashes and forward slashes are handled.

In my opinion, this is the simplest and most reliable solution. I hope you find it helpful as well.

Answer №21

Here's a helpful command that has worked for me. Make sure to run it in the Shell Terminal as an Administrator:

Answer №22

If you find yourself stuck with the problem mentioned earlier, a handy solution is to utilize either VScode or Visual Studio Code.

  1. To access the vscode terminal, simply press Ctrl + ` or navigate to the terminal tab and open it manually.
  2. Upon opening, you will notice several tabs and icons available for use.
  3. In the top right corner, look for a symbol 'v' next to the + sign; click on it and select cmd to proceed.
  4. For example: type tsc file.ts (replace 'file' with the actual name of the file you wish to compile)
  5. Once you execute the command above, a javascript file will be generated, in this case, named file.js...

Your issue should now be resolved...happy coding!

Answer №23

Visit the location

C:\Users\user_name\AppData\Roaming\npm
and delete the file named tsc.ps1.
