問題描述
python v.3.7.4 上最新版本的 virtualenv (16.7.2) 為activate.ps1"增加了 4 行.腳本，在 Windows10 powerhsell 上運行時會出現錯誤:You must 'source' this script: PS>..ENVScriptsactivate我該如何解決?(請注意，我已經閱讀并完成了其他論壇問題以及與 windows 和 powershell 相關的 virtualenv 手冊中提到的所有內容.)
Newest version of virtualenv (16.7.2) on python v.3.7.4 has 4 additional lines for the "activate.ps1" script, which when run on Windows10 powerhsell gives the error: You must 'source' this script: PS> . .ENVScriptsactivate
How do I fix this? (please note that I have read and done all that was mentioned on the other forum questions as well as the manual for virtualenv related to windows and powershell.)
我已將執行策略設置為 RemoteSigned(按照其他論壇的建議):
I have set the execution policy to RemoteSigned (as recommended in other forums):
Get-ExecutionPolicy -List
Scope ExecutionPolicy
----- ---------------
MachinePolicy Undefined
UserPolicy Undefined
Process Undefined
CurrentUser Undefined
LocalMachine RemoteSigned
當我想激活 virtualenv 時，我運行 .ENVScriptsactivate
When I want to activate virtualenv, I run .ENVScriptsactivate
問題在于創建新虛擬環境時由 virtualenv 自動生成的 activate.ps1 腳本的第 3 到 6 行:
The problem is with lines 3 to 6 of the activate.ps1 script that is auto generated by virtualenv when you make a new virtual environment:
if (@($null,"Internal") -notcontains $myinvocation.commandorigin) {
Write-Host -Foreground red "You must 'source' this script: PS> . $($myinvocation.invocationname)"
exit 33
}
似乎 $myinvocation.commandorigin 設置為 Runspace 而不是 Internal
It seems that $myinvocation.commandorigin is set to Runspace instead of Internal
我該如何解決這個問題?有任何想法嗎?謝謝 :)))請注意，我不想手動調整每個自動生成 activate.ps1 文件.
How do I fix this? Any ideas? Thanks :)))
Note that I don't want to manually adjust every auto-gen activate.ps1 file.
推薦答案
我們來看看那個錯誤信息:
Let's have a look at that error message:
您必須獲取"此腳本:PS>..ENVScriptsactivate
Hmmmm... - PS> 可能只是提示，給我們留下了這樣的提示:
Hmmmm... - PS> is probably just the prompt, which leaves us with this:
. .ENVScriptsactivate

# Check out this guy
那個，路徑前面那個孤獨的.，也就是powershell中的dot-source operator.
That, the lonely . in front of the path, that is the dot-source operator in powershell.
根據 文檔，它:
在當前范圍內運行腳本，以便將腳本創建的任何函數、別名和變量添加到當前范圍內.
Runs a script in the current scope so that any functions, aliases, and variables that the script creates are added to the current scope.
我沒有看過 virtualenv，但我認為它需要定義一些變量并確保這些變量在腳本運行后仍然存在，它需要運行在當前范圍內.
I haven't had a look at virtualenv, but I assume it'll want to define a number of variables and to ensure that these persist after the script has run, it needs to be run in the current scope.
所以這是你必須運行的 literal 命令來修復它:
So this is the literal command you have to run to fix it:
. .ENVScriptsactivate
