安裝python模塊時報錯如何解決

前言：

這幾天把python版本升級後，發現pip安裝模塊好多都報錯（暫不確定是不是因為升級導致的），我定睛一看，發現是權限的問題，那麼怎麼解決呢？

1 權限問題

C:\Users\ljfpip install xlwt

Exception:

Traceback (most recent call last):

File “c:\program files\python35\lib\site-packages\pip\basecommand.py”, line 21

1, in main

status = self.run(options, args)

File “c:\program files\python35\lib\site-packages\pip\commands\install.py”, li

ne 311, in run

e 803, in install

File “c:\program files\python35\lib\site-packages\pip\req\req_install.py”, lin

e 998, in move_wheel_files

isolated=self.isolated,

File “c:\program files\python35\lib\site-packages\pip\wheel.py”, line 339, inmove_wheel_files

clobber(source, lib_dir, True)

File “c:\program files\python35\lib\site-packages\pip\wheel.py”, line 310, inclobber

ensure_dir(destdir)

File “c:\program files\python35\lib\site-packages\pip\utils\__init__.py”, line 71, in ensure_dir

os.makedirs(path)

File “c:\program files\python35\lib\os.py”, line 241, in makedirs

mkdir(name, mode)PermissionError: [WinError 5] 拒絕訪問。: ‘c:\\program files\\python35\\Lib\\sit

e-packages\\xlwt’

注意看我標紅的那部分，提示說權限錯誤，拒絕訪問，我們這樣解決：

1 首先切換到c:\\program files\\目錄下，

2 我們鼠標右擊python35這個目錄，點擊 屬性 ，

3 首先切換到  安全 這個大標題下面，選中當前登陸的用戶，然後再點擊編輯，編輯完以後不要忘記點擊應用，

4 點擊添加的權限，我這裡為了方便全部一塊選了，反正根據自己的實際情況而定，最後點擊應用，再點擊確定就大功告成。

5 我們此時再看看自己pip，是不是能夠安裝模塊了。

python安裝失敗是什麼意思，怎麼解決，電腦是win7系統，64位？

【python安裝】錯誤——“User installations are disabled via policy on the machine”

解決方法一：

1、在運行里輸入gpedit.msc;

2、計算機配置管理管理模板windows組件windows Installer禁止用戶安裝;

3、打開它禁用此項就可以了。

若方法一不行，請使用方法二：、

1、進入註冊表目錄：HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer

2、將 DisableUserInstalls 的值改為 0再安裝即可

python庫安裝錯誤 in _error_catcher解決之鏡像安裝（轉）非常好用

pip install grpcio-tools

1、出現如下錯誤：

解決方案：pip install grpcio-tools -i

後面的-i 即是鏡像

如何解決python安裝啟動報錯

解決python安裝啟動報錯的方法：

打開系統的環境變量path，將python的安裝路徑添加進去，然後確定，重新啟動python就可以了

示例如下：

安裝python出錯2503怎麼解決

第一種解決方法：

原因就是C：WindowsTemp文件夾NTFS權限錯誤，將它的user權限改為完全控制就OK了。

第二種解決方法：管理員命令行安裝

複製安裝包到c盤

1.運行CMD（以管理員權限運行）

2.進入c盤根目錄

3.輸入以下命令：msiexec /package “c:python-2.7.13.amd64.msi”
