How to use the azure-pipelines-tool-lib/tool.cleanVersion function in azure-pipelines-tool-lib

async function acquireTfx(version: string): Promise {
    try{
        version = toolLib.cleanVersion(version);

            throw new Error('Expected Agent.TempDirectory to be set');
        }
        extPath = path.join(extPath, 'tfx'); // use as short a path as possible due to nested node_modules folders

        taskLib.mkdirP(path.join(extPath));
        const npmRunner = new tr.ToolRunner("npm");
        npmRunner.arg(["install", "tfx-cli@" + version, "--prefix", extPath]);

        const result = npmRunner.execSync({ failOnStdErr: false, silent: true, ignoreReturnCode: false} as tr.IExecOptions);
        if (result.code === 0)
