sourceing setup.sh給出了bash錯誤/tmp/setup.sh.DPE4BtgiZY：無法覆蓋現有文件

我試圖安裝最新的ROS Hydro，所有事情都很順利，因爲一切似乎都已下載並配置到適當的位置。每當我使用ros時，我都會提供一個設置腳本。當我試圖發生的問題：發生sourceing setup.sh給出了bash錯誤/tmp/setup.sh.DPE4BtgiZY：無法覆蓋現有文件

source setup.sh

一個錯誤：

bash: /tmp/setup.sh.DPE4BtgiZY: cannot overwrite existing file 
bash: [: 0: unary operator expected

我試圖運行該腳本以root或使其成爲一個可執行文件，但沒有工作和相同的錯誤仍然存在。下面是

清理/tmp/setup.*並再次運行 – michael501

@邁克爾我已經嘗試已經，沒有一個文件一樣，在'。/ tmp /'中。我試圖清空整個'。/ tmp'目錄，但問題依然存在。 – cyc115

我做了兩個修改爲setup.sh得到它的工作的setup.sh：

在「調用的Python腳本生成的環境變量需要出口」變化

CATKIN_SHELL=$CATKIN_SHELL "$_SETUP_UTIL" [email protected] > $_SETUP_TMP

到

CATKIN_SHELL=$CATKIN_SHELL "$_SETUP_UTIL" [email protected] >> $_SETUP_TMP

在「源中的所有環境掛鉤」從

while [ $_i -lt $_CATKIN_ENVIRONMENT_HOOKS_COUNT ]; do

改變而框的終止條件來

while [[ $_i -lt $_CATKIN_ENVIRONMENT_HOOKS_COUNT ]]; do

的誤差應該消失。
