示例1: changeJuliaEnvironment
async function changeJuliaEnvironment() {

const optionsEnv: vscode.QuickPickOptions = {
placeHolder: 'Select environment'
};
let depotPaths = await packagepath.getPkgDepotPath();
let envFolders = [{ label: '(pick a folder)', description: '' }];
for (let depotPath of depotPaths) {
let envFolderForThisDepot = path.join(depotPath, 'environments');
let folderExists = await fs.exists(envFolderForThisDepot);
if (folderExists) {
